Nearly everyone, nowadays, either has a laptop computer or is clamoring for one. Even those who already have a unit, desire to purchase newer models, which are more advanced and have tons of features. The question is, how can all these people afford the rather expensive gadget? The best models are worth hundreds of dollars or even more, and, for some reason, a lot of people have them. One of the reasons is, they may have gotten their units for free.

Avenues for Free Laptops

Silly as it may sound, you could actually secure a free laptop from quite a number of sources. Both schools and industries recognize the importance of laptop computers, promoting efficiency as well as raising profits, which is why they hand out free units, at times even some of the best models on the market. You can take advantage of these deals, as you get to take home one of the hottest electronic gadgets right now.

Free Laptop Promotions

Dangling a free computer in exchange for purchasing a few items or participating in a promotional gimmick is enough for customers to bite deals. Let’s face it, everyone wants to have a portable computer and getting one without paying or without paying much sounds pretty attractive. A lot of companies use this ploy to gain ground on the market. If you search online, you’ll find a multitude of websites offering such a promo.

Free Laptops for Students

School is where students learn concepts and how they are applied. But that’s only one half of the learning process. The other half is spent outside the classroom, where skills are honed, theories remembered, and concepts applied. With a laptop computer in hand, all of these are made possible, which is why many schools provide units to students, especially those who are enrolled in computer courses. Due to this, some students enroll at those institutions that provide laptops, earning the schools more profits.

Gee, a Laptop Freebie

For many, participating in an endeavor which will get them a free laptop is just too good to pass up. Imagine tinkering with your social networking account at your favorite coffee shop, cheerfully sipping espresso as you prepare a barrage of eye-opening status messages. It’s bliss. Better secure a free laptop soon.

Greg J Thompson knows a great deal about free laptops and can find you some great specials on laptops deals if you visit his site now.

The internet has given rise to several possibilities that a few years ago were unthinkable. Storage of data has evolved from floppy disks to CD. Disk drives those are portable to pen drives and the most convenient among all being storing data online.

With online data storage it is now possible to have all of your vital information, business presentations, slideshows etc stored on any of the online storage software that is available. This data can then be retrieved from any destination using a simple internet connection. Online data storage is advantageous in many ways, Infact apart from the internet giving up on you and the software not working at times is the only downfall that one will face when in times of information retrieval.

Online file storage is acceptable in all formats and are not narrowed down to just word documents or PowerPoint presentations. With a remotely located server it is possible to store all types of files and presentations, thereby making it much convenient for a person who is constantly on the ‘Go”. The possibility of the remotely located server crashing or not working is very rare, and erases the reasons for carrying any other technical gizmos that help in data storage.

With online data storage it is possible to store data remotely for all types of small and medium sized business as well as enterprises and personal users. Secured servers are constantly updating their firewalls and virus software’s; this makes it a much reliable storage source that keeps your data safe from all types of natural disasters, human and technical error.

There are several data storage providers who now have tweaked their storage software’s so that every individual finds it easy to store their important data online. Most of the storage providers allow upto 5GB or more storage space that is usually free to use. Some of these can be named offhand, like Google, MSN etc. Along with excellent customer support that is available both offline and online, it is now easy for a user to open an account with any of the providers and start downloading their information on these online storage servers. The online storage space is available without any hassle, contract or commitment and one can easily cancel the account at anytime at will.

With this kind of ease it is now possible to store data, music, business files and presentations online and can be accessed from any part of the world. Another great feature that these online storage software’s provide is the sharing of files, documents and pictures among friends, family and associates.

Using the online storage is extremely simple, most of these software’s offer the traditional method of uploading the files, whereby 5-10 files are selected and then uploaded. Another method is by downloading the storage software onto the system that helps in both uploading and downloading of all your important files, folders and documents. After you upload the files or folders you will have the option of sharing the files for e.g. Pictures among friends and family. You can also access your files whenever and wherever you want to.

Small and medium sized business can now have their disk storage backup along with recovery of these files done with ease which is also 100% unswerving and does away with any forms of recording tapes. Since the remote server backup activity is regularly carried out on a scheduled basis, you can be rest assured that your data that is stored online is safe. If one requires restoring any backed up data, all they need to do is login to the website with their unique ID and Password, select what is required and then restore it. Another advantage is that, there are server specialists always working to ensure that your data is safe and secure at all times.

Online File Storage is now possible with Storage Software that make Online Data Storage accessible anywhere and anytime.

A Trojan virus is a faulty computer program that can infect remote computers by changing the desktop or deleting important files. Generally called a Trojan Horse, it appears as a legitimate file or software from a trusted source, therefore tricking users into opening it or downloading it. A Trojan refers to a program that appears as something you may think is safe, but hidden inside is usually something harmful, probably a worm or a virus.

Take action and protect your irreplaceable computer files, credit card number, bank account number, social security number, address, drivers license number, pictures and important work documents by learning how to remove Trojan viruses ..

The lure of viruses is that you may download a game or a picture, thinking it’s harmless, but once you execute this file (run it), the worm or virus gets to work. Sometimes they will only do things to annoy you, but usually a worm or virus will cause damage to your system.

If you are currently infected I strongly advise you to learn how to remove a trojan virus yourself. If you don’t you will run the risk of being hacked and have all your personal information taken.

Learning how to remove trojan viruses can be a very technical task. I would not suggest you follow any instructions that teach you how to remove trojan virus unless you are very competent with computers. If you aren’t comfortable with computers I suggest you use a program, it will remove them so you don’t have to know what to do.

What could happen if your precious information fell into the wrong hands? You could suddenly get a credit card statement that has outrageous charges. It’s not the money thing that will hurt, its the time you will have to take to get all those charges resolved. Just because one trojan virus stole your information. Somebody could have a hay day with your social security number.

Instructions

Disclaimer: Do not attempt to remove them by yourself unless you know for sure what you are trying to accomplish.If you want to learn how to remove trojan virus, you will need some computer savvy.

Step 1:The first thing you must do is stop the process(program files) from running. This can be accomplished by getting into your task manager and stoping the process you suspect are the trojan virus.

Step 2: Un-register the trojan virus files. In the Run command box, type “cmd”, and then click on “OK”. Type “regsvr32 /u filename.dll” where “filename” is the name of the file that you like to Unregister.

Step 3:Remove and Modify Registry Entries if they exist. Click Start > Run.
Type regedit. Then click OK.

Step 4: Search your computer all files and hidden files and delete these Related Files if they exist.

You will need specific file names and specific registry entries in order to completely remove a trojan virus. If you cant find these file names and registry entrys you can always use a program that will delete the trojan virus for you.

Don’t let these trojan viruses steal your important information, make sure you clean them up now.

If you’re familiar with ZigBee, you’ve no doubt seen a picture of the stack with IEEE 802.15.4 at the bottom, ZigBee in the middle, and applications and profiles sitting on top. This article looks at the top bit of the stack, and at how ZigBee profiles make it easier for you to create your own interoperable applications.

ZigBee is an open standard, which is ideal for applications that require long battery life, low cost, small footprint, and mesh networking to support communication between large numbers of devices in an interoperable and multi-application environment.

One of the ways interoperability is achieved is through application profiles. These profiles are defined by the ZigBee Alliance, and provide a description of the devices supported for a specific application together with the messaging scheme used by those devices for communication–in effect, defining the type, shape and features of the network.

Adherence to these profiles guarantees the interoperability of different vendors for the same application space.

Each application profile addresses the needs of a specific application market. Profiles are currently available or in development for the following types of applications:

  • Smart Energy
  • Home Automation
  • Telecom Applications
  • Commercial Building Automation
  • Personal Home and Hospital Care

Endpoints and clusters

Devices are defined by profiles and implemented as application objects. Each application object is connected to the rest of the ZigBee stack by an endpoint, which is an addressable component within a device.

For example, a remote control might allocate endpoint 6 for the control of lights in the master bedroom, endpoint 8 to manage the heating and air-conditioning system, and endpoint 12 for controlling the security system. This allows the remote control to independently communicate with these devices and identify which packets are intended for each application and device.

Communication is made from endpoint to endpoint through data structures called clusters. Clusters contain a set of attributes that represent device state together with commands that enable communication between application objects. Each cluster is identified with a unique ID.

Clusters used in a specific application are defined within its profile. For example, the Home Automation profile contains a cluster dedicated to the control of lighting subsystems.

Each cluster has two ends:

  • The client/output requests and manipulates the data.
  • The server/input has the source data.

The ZigBee Cluster Library (ZCL)

All ZigBee application profiles are defined using clusters from the ZigBee Cluster Library.

This library allows common clusters to be reused across a number of different functional domains, for example, the same lighting clusters can be used for any application that requires lighting control, such as home automation and commercial building automation.

Clusters within the ZCL are organized into a number of different functional domains, including Lighting, HVAC (Heating, Ventilation, Air Conditioning), Measurement and Sensing, Security and Safety, and General.

Each cluster specification within the ZigBee Cluster Library defines

  • mandatory and optional attributes
  • cluster-specific commands
  • functional description

Each device specification within an application profile defines

  • mandatory and optional cluster usage
  • values of free parameters in the ZCL
  • any additional functional description

Bindings

At a high level, binding is the process of establishing a relationship between two devices that can communicate in a meaningful way, for example, which switch controls which lights. Each binding supports a specific application profile, and each message type is represented by a cluster within that profile.

Bindings can be created between either individual or groups of endpoints, such as lights and switches, that have matching input and output clusters (with the same cluster ID). ZigBee devices can have up to 240 endpoints, so each physical device can support multiple bindings.

Conclusion

By providing the ZigBee Cluster Library and application profiles, the ZigBee Alliance has already done a lot of the hard work for you.

If you need your device to perform a specific function or behave a specific way, there is no need to create things from scratch. You can simply implement the ZigBee cluster that already exists for that purpose.

Adherence to the application profiles and the ZCL also helps to achieve ZigBee certification to ensure interoperability with other ZigBee devices.

How Electric Pressure Cookers Work

The quick rise in popularity of wireless networks determined a quick decrease in equipment process that coincides with an accentuated enhancement of their technical performances. A wireless network can be completed today with expenses that are mush lower that the ones associated to a regular wired network. This is why we can foresee the rapid and cheap internet access of all members of a local community, with all benefits that come from this.

The access to global information constitutes a rich source of wealth at a global scale, by raising work productivity that is based on the access to all information available around the world regarding the respective company activity. At the same time, the wireless network becomes more valuable as various different people connect to it. Communities that are internet connected have access to a worldwide market where more and more transactions are made at network speed.

At the same time, the internet access allows people to discuss their problems, their politics and any other topic they might be interested of in ways which the telephone or television can not provide. Even without internet access, communities that are linked through wireless networks can enjoy various advantages: they can collaborate on different projects with geographical coverage using vocal communications, e-mails and data transitions with very low costs. Ultimately, people understand that these networks are made so that they can reach each other easier.

The importance of a wireless network in an office or even at home has become crucial. Because everyone can gain access to such technology, there is no point in turning back to wired networks. And since many people are using laptops to provide their computer needs, it would be quite strange to wire them to a network since they are made to be portable. Since a laptop can be used in an alley or park, people feel the increased need of accessing the internet in various locations, so a wireless network is also necessary.

The only problem that is worrying about wireless networks is that they are not as secure as the wired ones. Even if all firewalls and windows updates, if one does not secure the network properly, various people can gain access and then enter the confidential files on that computer. It’s just like leave a door open in a house, without warning intruders that there is a private property. Common sense would make a civilized person not enter, but not all people are like that and many will take advantage of the nativity of others.

The globalization of wireless network has become obvious with the massive success of the cell phones, which also function on wireless principles. Since then, wireless network are very often used and growing faster by the day.

PCB stencil online quote

Though the internet in some form or the other existed for a long time, the popularity of the worldwide web in the 1990′s changed the face of the information technology forever and in a positive way. Literally a whole universe of information opened up for not only the net savvy but also anyone who had some basic knowledge of computers and who ventured into this expansive universe of the net. Internet is indeed referred to as the information highway. The current day internet has not only reached a mammoth size, but also is ever evolving and expanding. It is such a fascinating tool which has no boundaries and no limits. The saying that the sky is the upper limit can’t be more applicable to this field.

The internet or the’ world wide web’ not only is a perfect medium for communication between people across the globe but also is fast becoming a preferred medium of business transactions. E-Commerce is thus the tool to which big business giants of the globe are resorting to conduct their business. This does not mean that the smaller businesses are at a disadvantage. They too make full utility of it. It is not difficult to imagine the potential of the web to identify the vast market potential available. With the real time deals and the secure means to make the related financial transactions the internet is luring more and more people to it. It is quite natural that with such a vast potential and monetary involvement, the internet and especially the e-commerce faces challenges from the hackers and like who keep on attacking it. Thus emerge real security issues which need constant vigil to make the e-commerce safe.

The spectrum of e-commerce is as diversified as the net itself. People can buy anything ranging from a needle to a jumbo airliner through the internet. Finding and then possessing a much loved and desired book is as simple as a click on the net. Making hotel reservations for flights and Hotels worldwide is now a reality. Even participating in an auction is not something out of the scope of e-commerce. An ever increasing population makes use of these facilities from the comfort of their homes. Like any field which is changing its face rapidly, it is also ever evolving. The enormity of the web and the innumerable web sites available make it difficult to attract customers to specific sites. The businesses therefore have to constantly search methods to attract the potential clients towards their web sites, long before they make a real purchase. It is not only the buying activity of the customers on the worldwide web which contributes to the e-commerce but also the net is a source of lively hood to the ones involved with it.

Thus the internet is not only a medium of communication between people of the globe but also is a potent engine of business activity through e-commerce. By observing the current trends, it can safely be assumed that the coming days are surely going to witness an ever increasing adherence to e-commerce by an ever growing population worldwide.

For the last 10 years, I have been writing about what to do to keep you and your computer safe and secure. Now, for a change, I will talk about what NOT to do to keep your PC nice and healthy for many years, while YOU avoid a lot of frustration, lost time and a lightened wallet.

1. Do not turn off your computer using the switch on the power bar. Use the proper procedure, i.e. click Start, Turn Off Computer, Turn Off. If your computer freezes or you get the dreaded Blue Screen of Death (especially if you still have Windows Me), try the good ol’ CTRL + Alt + Del before hitting the Reset button, or doing anything else.

2. Never turn off your PC while you are in a program, or have multiple windows open. Close all the windows and applications first.

3. If you turn your computer off for any reason, wait a minute or so before turning it back on again. This allows the machine to clear memory and get ready for bootup.

4. Never connect new hardware while the computer is on. Turn everything off, connect your hardware, then boot up again.

5. Never push the release button on that CD or floppy drive until the drive light goes out. Never force a disk into the drive. If it will not go in easily, check for pilot error (you may have it backwards or upside down!)

6. Here is an old one, but still necessary: Keep magnets away from those floppies, and far from your computer as well.

7. Never bring food or especially liquids near your PC. If you do spill something on the keyboard, clean it up immediately. If the keys stick or you have other problems, as a last resort you can run the keyboard through the dishwasher, top rack, face down, with no soap. Let it dry for a couple of days, then try it.

8. Do not fall for phishing scams on the Internet. Follow this one simple rule: If you want to go to the Web site of your bank, broker, eBay, etc. click your Desktop icon or Favorites link, or TYPE the address into the browser address bar. Never click links to such sites in an email or on a Web site. Never copy and paste your username or password. The contents of your Clipboard can be seen.

9. Do not download anything unless it is from a trusted and reliable source, and you really need it and will use it. Screensavers are a favorite hiding place for malware. If you want a new background or screensaver, check your Windows first. Right-click a blank area on your Desktop, and click Properties, Desktop (or Screen Saver).

10. Do not accept offers you may see online to scan your computer or Registry for viruses or spyware. Some of these programs will report an infection where none exists (false positive) to scare you into buying their software. Even worse, other programs may actually infect your machine with malware. Besides, you do have a full set of security programs already, right? If not, get them!

You may want to print out this list and keep it handy. Or better yet, why not send it to your friends? Happy (and safe!) surfing.

Great news! I have prepared a special offer for you, dear reader. I am sorry I cannot tell you exactly what it is right here because it changes all the time, as I scour the Internet looking for great deals for you.

I can only tell you, I think you will love it. Believe me, it is worth a click to take a peek here. Hop on over here http://www-antispyware.com/ to see what Today’s Special is!

The cost of using ‘paid for’ business software has become prohibitive. Both businesses and home users are focusing on new and affordable avenues.

The options include free software:

o StarOffice: The code base can be accessed at OpenOffice.org. This is the group coordinating the development of the product. OpenOffice .org runs on Windows, Linux, Solaris as well as Mac.

o Version 5.2: enhances browser compatibility and has the latest security and performance related enhancements.

o 602ProPC suite: Free after registration it is MS office compatible.

o EasyOffice Freeware: For personal use, it has ten applications; a text speech program and Adobe PDF file creation.

o GNOME Office: A part of the free GNOME Desktop for UNIX, many of the applications are stable to use but in development.

o K Office: Runs on UNIX, Linux, and FreeBSD, the office suite has eight important applications.

o OpenOffice.org 1.0: Based on StarOffice 5.2, this is a complete system offering word processor, spreadsheet, drawing program, presentation program, and equation writing. Compatible with Windows, Linux, and Solaris.

o RagTime Solo: Designed for desktop publishing, built in functions include: word processing, spreadsheet, and graphics. This is free for personal use.

o SOT Office 2002: Runs on Windows and Linux and has, a word processor, spreadsheet, a drawing program and a presentation program.

These are just a few examples from the many options available. Most of the above are high quality and glitch free. There are no initial costs or upgrading pressures. Most work efficiently on older computers which means, one can exit the cycle of constant forced upgrades.

Free software offers a freedom for the user to run, copy, understand, as well as modify the software. There are no restrictions, the program can be adapted to suit specific needs, and, it can be distributed along with the adaptations/improvements. The term free denotes access to the source code and not just to costs.

The advantages are:

o Cuts down capital outlay.

o Is constantly evolving as users provide valuable inputs and feedback.

o One can make modifications. Go beyond the interface and understand the workings. Plenty of user group support is available.

o Access to the source code increases user options. Permits unrestricted use of software, permits free sharing, as well as individual modifications.

o No obligations to the company. Freedom from dependencies on multinational companies who create a monopoly.

o Little or no maintenance and upgrade problems. Extends the lifespan of older hardware.

o Many are fast, hardy, as well as reliable. This can be credited to the open system of development, implementation, and testing.

However, one must find out if there are any disadvantages to the free software selected for use.

Consider:

o Is the software established?

o Are updates, patches, and new features freely available?

o What about support?

o How widely is the software in use?

o Is documentation understandable and complete?

o Are there any maintenance costs?

o Is there a forum that helps in case of problems?

Make a detailed study of your needs, then study all the options in operation, if a related business is using a particular system find out their experience and why they chose the system. Knowledge is power and a reliable guide.

Impact of Radio Frequency Identification Technology

The Environment consist of the all elements that are outside the system under consideration, and which it must take as given .The environment also include all the external impositions and constraints other than those imposed by the ownership.

The External environment cannot be ignored otherwise they will cause messy in the information System, in soft engineering mode of enquiry it emphasize a process of enquiry without forgetting external environment factors

The success of an organisation introducing RFID technology into its business depends strongly on a proper analysis of the environment it is operating in, a careful analysis of the environment should be carried out.

Economic impacts

In the retail Industry and manufacturing sector it is difficult to imagine a time when items flowing through a warehouse or distribution center were not automatically sorted using bar code labels. It is possible, however, to imagine how that process could be improved with RFID tags. In this application, RFID tags make a good process better (with the economic impact depending on how “good” the performance of the current bar code system is):

Beyond pure cost reduction, RFID-enabled sorting supports supply chain processes that are currently difficult or impossible with bar code technology. Higher data capacity in RFID tags allows more detailed and flexible sorting. Sophisticated customers sometimes specify detailed palletizing criteria for each order to facilitate cross-docking at their distribution centers. An order encompassing one pallet of facial tissue, another of bathroom tissue, and one of paper towels might require reconfiguration so that the customer receives three pallets, each with a mix of products and each destined for a different store. Data on an RFID tag could include not only to which outbound dock a pallet of towels should be transported, but also how it should be stacked before delivery. It is even conceivable to embed in a pallet tag the destination, contents, and stacking configuration of the pallet for use by the customer. If store conditions change between the time an order is shipped and when it is received, the customer could write different destination information into the pallet tag, or use the stacking information to automatically break and repack the pallet.

Hewlett Packard (HP) was an early adopter of RFID technology and has used the technology to gain supply chain efficiencies. He said that HP began RFID testing in 2002 and has been tagging pallets and cases in response to the Wal-Mart mandate. RFID benefits that have since accrued to HP include the elimination of manual processes for inventory control, decreasing inventory control time, and realization of downstream benefits in areas such as product returns and retirement.

There are also negative impacts, example the issue of Job cuts. If chain stores started to invest in this technology to process purchases, sidelining human check-out operators, then those employees may find themselves out of jobs, and this will have a negative impact towards economy as many people will be unemployed.

Global impact

Now that global standards are emerging in the design and implementation of RFID, businesses that implement RFID will find their products more acceptable globally and supply chain of their products will expand

Social Impacts

Any new technology has social consequences. These are usually seen as side-effects to the actual goals of the technology, and may not be visible for many years after the deployment of the technology. When the social impact of the technology is recognized late in the life-cycle of the technology, it is difficult and costly to make the changes that will mitigate these negative effects. It is therefore preferable to anticipate the social impacts and build safeguards into products early in the development thus saving money and development time.

A primary social concern regarding the use of RFID technology is that of privacy. As RFID tags are added to consumer goods or to items that will be associated with individuals such as identify cards or records, RFID has the potential to allow the tracking of the location and activity of individuals, and the creation of records of this tracking in databases, all without the individual’s knowledge.

The scary part of the use of RFID tag is that products bought with an RFID tag on it could all be traced specifically to the buyer just with the help of the tiny chip inside. Many people are already thinking this could potentially become a “Big Brother” problem.

RFID is not only the harbinger of heavy personal surveillance. It may bring an end to civilisation. The end of supermarket check-outs and their staff may seem ideal for some, but for me it sounds like hell on earth. One of the joys of being a human being with an active mind is the ability to engage others in conversation. An environment which encourages customers to shop quickly and avoid interaction with others further atomises society. We already spend a great deal of our time `entertained’ by television or video games, avoiding contact with the real world. An end to supermarket staff would only increase our hermit-like status, acclimatising us to a world where real people are not important.

Political Impacts

Politics is a factor that should be considered when an organisation is deploying RFID technology. Issue like privacy will definitely lead various governments to formulate policies and legislation could get in the way of a positive use of RFID technology. It will also led to laws like consumer private protection act being amended to cover more privacy issues of consumers

Technical Impact

Technology is essential for competitive advantage, and is a major driver of globalization. RFID technology has many advantages over the traditional ways of tracking and identifying products in a retail environment.
RFID will have a massive impact on the technical side, as the company will need to change the whole infrastructure and capability of their information system will need to be expanded to accommodate RFID transmission data

Impact of RFID on IS Strategy/planning (IT Strategy)

The issues surrounding the hardware implementation of RFID concern the types of tags you are going to use, the environment they are going to be used in and how readers need to be configured. The hardware side concerns number and location of readers, a not inconsiderable investment in some instances. If a store deploys smart shelving, then it will require that short-range readers be deployed to all shelves to be covered. Then they need the infrastructure to transmit data capture to the relevant back-end systems. Such infrastructure could be wired Ethernet or wireless 802.11 to reduce the cabling costs.

To realize the benefits of RFID, IT will need to upgrade its infrastructure in a number of areas, and the interfaces with the business will have to be closer than ever before. There are three areas that will be needed to be addressed: data management, network and end-user device management, and a new category for many IT organizations, sensor management. In addition, tying all these together and integrating them with legacy systems will require a new level of systems integration capabilities.

Data Management

The amount of new data generated from RFID will be enormous. Today’s systems and supporting data infrastructure often focus on the latest status or end state of a product, asset or person. To support RFID, this data model must be expanded to capture additional information around and about events: the state before, during and after each step; the people and assets involved; the conditions at the time; and key measurements and metrics.
IT will need to decide whether to integrate this additional information into the existing corporate data infrastructure or develop a separate management structure. Business-rule definition and data analysis capabilities must be upgraded, as data and events need to be analyzed as close to real time as possible to provide the intelligence and monitoring necessary to make processes more efficient and avoid or quickly correct mistakes and problems.

Depending on the industry and the business operations affected, the IT organization may find itself pushed toward a more decentralized computing and data management infrastructure than it would otherwise have planned. Finally, data security, privacy and storage will pose new challenges due to the volumes and real-time sensitivities involved, particularly with human track-and-trace applications.

Network and End-User Device Management

A great variety of data extracts and information views will need to be made available throughout RFID-impacted operations. As often as not, the end users of this information won’t be at desktop computers, but mobile, requiring deployment of wireless LANs and other remote connections in areas not being addressed today.

In addition, information views will be need to be constructed assuming that a handheld computer, device or even a cell phone will be the recipient’s platform of choice for receiving information and providing updates. These compact platforms will require new thinking in how to process a great deal of data in ways that provide essential information to the user yet doesn’t filter it excessively, in a readily useable format. For location data, geographical information systems can play an important role in graphically depicting large volumes of information in a concise manner.

Sensor Management

IT organizations will need a new set of capabilities and skill sets to manage the proliferation of RFID readers and tags and to understand the processes within which they operate. To effectively provide sensor management, IT needs to ensure that standards are set for tags, readers and how they are deployed.

Different applications may require different standards on dimensions such as system frequency, read range, passive vs. active tag power, accuracy, reliability, placement, polling frequency and environmental conditions.
Maintaining and repairing readers will also be a new capability, and the speed of repair will become an important metric. Also, certain applications will require multiple readers near one another, sometimes resulting in conflicts and troubleshooting delays.

In repair situations, it will be important to have a backup or contingency process in place to ensure uninterrupted operations. IT is the logical entity to take the lead in designing and implementing such processes. IT professionals will need to become much more proficient in business operations then they have been historically. RFID will push IT into many corners of the business where before it may have only been involved peripherally.

Systems Integration

The challenge of tying all the piece parts of RFID together in a smooth and reliable manner will perhaps be the greatest challenge for IT organizations. In many ways, deploying RFID is like deploying a whole new IT infrastructure, with new data sources, processing mechanisms, recipients, network capabilities implemented where none were previously needed and a new category of devices to communicate with and manage.
That doesn’t mean legacy systems won’t be involved. On the contrary, many RFID applications will need sophisticated interfaces and other operations support systems. For example, hospitals will need to interface their RFID systems with legacy hospital information systems, picture-archiving and communications systems, electronic medical record systems and computerized physician order-entry systems.

Perhaps most important, a new level of business-process understanding will be required, and deep operational ties will be needed between IT and the business. IT professionals must fully understand the technology and the business operations to which it will be applied; they no longer have the luxury of being at the periphery of how the business operates.

Potential problems involving RFID (Risk assessment)

Risk is the situation where there are several possible outcomes and the probability of their occurrence is unknown. In deciding on the course of action in strategic management there is an attempt to assess the risk involved, that is the outcome of the alternatives.

All courses of actions carry risks; even doing nothing is a risk.
According to Tim Hannagan in his book of Mastering Strategic Management 2002, he explains the risk analysis checklist which can be used when assessing the risk. The risk analysis checklist will involve the following:

Life cycle- Questions of growth and decline in terms of products and service sectors

Substitutes-To the product and service offerings.

Environment factors-such as changing legal, social and economic pressure

Operational issues-in terms of capital resources, staff competencies and management skills

Critical Success factors-identifying exactly what is required for the success of the organization

Evaluation of the worst -case situations, contingency plans and consequences of strategic decisions

Ethical and pollution issues-and their effect on the organization

Therefore, the following are possible risk to be taken into consideration before deploying the RFID Technology

Risks for privacy-the debate over RFID technology touches upon many controversial policy issues. At its most fundamental, widespread use of RFID tags could enable corporations to track every move consumers make. Corporations which compile the data transmitted by the tags could determine which products a consumer purchases, how often products are used, and even where the product – and by extension the consumer – travels. By aggregating data to form consumer profiles, corporations could make inferential assumptions about a consumer’s income, health, lifestyle, buying habits, and travels. This information could be sold to governments to create dossiers of individual citizens, or simply sold to other corporations for marketing purposes. While the ability of RFID readers to collect data from tags once a consumer has left a store or moved beyond the readers’ range is currently limited, many consumer groups and privacy advocates note that RFID technology is quickly advancing, while measures to protect individual privacy by limiting the amount and type of information corporations can collect about consumers is lacking.

Skills shortage -a lack of qualified RFID integrators has hindered adoption of the technology for many companies. Organisations are already challenged, because many of the skills required for successful RFID implementations are not typically associated with IT staffing. A survey carried out earlier this year by global IT trade association CompTIA of its members found that 80% of companies do not believe there are sufficient numbers of professionals skilled in RFID available for hire. In addition, 53% of companies said this will have a negative impact on the adoption of RFID technology in the next few years.

Network breakdown and software failure- this can be the result of overload (not enough bandwidth), component failure, virus attack, power surge etc. It has the effect of bring down the operation of updating databases with information read from tags. If this happens the company may lose data regarding stock of the products.

Malicious users – There as been many talks about RFID privacy but little is time is devoted to issues like criminal gangs developing devices that could read the contents of RFID tags by just walking past you. Thousands of credit cards information could be obtained in this manner.

To reconcile negative impact of consequences (Conclusion)

There are two general areas where work needs to be done to assure that RFID can be employed without having a negative impact on individual privacy. The first is in the development of the technology itself. With privacy protection as a stated goal, engineering decisions can fulfill that goal. Techniques like encryption, system security, and the ability to easily turn off or “kill” an RFID tag can be made part of the RFID standard. All of these are possible today, but some are considered to be extra features rather than basic capabilities.

The second area is in business practices. Engineering alone cannot solve social problems; ethical practices and education of employees and consumers are effective tools when dealing with the impact of technology on society. Prior to the implementation of any RFID system that may be associated with individuals; a business must study all areas where such an implementation could have an effect on privacy. Relevant laws and statues must be considered, as well as industry or company policies. A statement of principles relating to privacy, the use of RFID, and the use of any databases of consumer information associated with the ID system can both guide industry and provide an opening dialogue with consumers. This work has begun in some areas: the American Association of Publishers has adopted a privacy statement on RFID in coordination with the American Library Association; the Federal Drug Administration’s Compliance Guide for RFID use in pharmaceuticals contains requirements relating to privacy. These early efforts will inform others. The essential message is that now is the time to address the privacy issues related to RFID, before the technology matures, before systems and applications are developed, and before business practices are in place. With early planning and the development of industry-wide best practices, RFID can create efficiencies in the supply chain and gain consumer confidence.

The company should also make sure that they have enough skilled labor in the process of implementing the RFID Project, also software and hardware requirements should be taken into consideration as well as the cost analysis before implementation of RFID.

Cool mobile gadgets

This printer is rather large, mostly in height, and weighs just over 30 kg (with all toner cartridges and other fillings). Cartridges are installed vertically along the front wall ensuring a sufficiently rapid single-pass color printing. Below is the main cassette tray for 500 sheets.

To open the multipurpose tray, you need to disassemble almost the whole front cover. The tray takes a lot of space, but it is not designed for frequent use, except for occasional printing of a page or two. On the right from the multipurpose tray, there’s a USB port for flash drives.

The Aculaser C3800 has a function of secure printing implemented with the USB port. It’s simple — no need to enter passwords on your computer first, and then on the printer control panel, simply use a flash drive.

On that same right-side wall, there are the power button and interface connectors. USB and Ethernet slots are hidden in a fairly deep niche you can access by lifting a small lid.

The output tray is deep enough to accommodate a 250-page document. For insurance, you can set the plastic catcher, although during tests paper never fell off. At a high speed of printing, the printer does not spit out ready documents, but gently lays them into the output tray.

Control Panel is rather standard, with a small but quite contrast LCD display. Navipad of four buttons is useful; the cancel button is located in a noticeable place, which is good.

To get to the cartridges, you need to open the entire front panel of the printer, together with the control panel. Cartridges are arranged vertically; removing and installing them is very easily, just pull the little handlers of the same color, which is located on the toner cartridge.

Driver of the Epson Aculaser C3800 is very much similar to that of inkjet printers, and from them it adapted the “Photo” tab in the simplified menu.

On the first tab, you may set the printing quality, paper size and paper source. On the same page, when you click the “Advanced” button, a tab with color management and resolution setting opens. There you can switch between color and monochrome printing modes, different color management presets; you can also manually adjust brightness, contrast, saturation and color.

Single-pass design makes it possible to print monochrome and color documents with virtually the same speed. This is exactly the case with Epson C3800: printing of color and monochrome text document took the same amount of time (20 pages per minute), although the specifications for black and white printing are 25 ppm. Printing a complex document (text and graphics) at 1200 dpi took almost 10 times longer than at 300 dpi. Don’t waste your time on that — you’ll unlikely to get a better quality, except if the document has a lot of photos.

Printing quality at the resolution of 300 dpi is good in general, although the contours of letters are not very clear, the text reads well in 4 pt font. At 1200 dpi the contours of characters are much clearer, once again 4 pt fonts are well-read.

In terms of color, you can hardly find fault in the C3800. The colors are juicy, rich, without gaps and fills. Photos are printed almost perfectly: no spurious tones, only monochrome images manifested slight blue tint. Good details without clearly visible raster; tonal and color transitions are smooth.

Epson Aculaser C3800 operates silently, has capacious toner cartridges, and menus and driver have a user-friendly interface. The rate of printing is not the fastest, but enough for most needs. Outstanding color reproduction with Epson toners is recommended for printing of presentations and brochures.

Every personal computer connected to the internet is open to attack from a pathogen, spyware, hoax emails and phishing. Now attacks may also damage or delete your vital info, or install malicious software which may also steal your passwords, credit card details or use your PC to attack other strategies over the web. According to Symantec, an unprotected, unpatched PC system is attacked within 20 seconds of connecting to the web. The after 10 guidelines below may help in safeguarding a Windows XP computer from such attacks, help to protect your important information, and save you the expense of a PC repair.

How the way does one choose the best antivirus software? Really, you actually must first find out the simple way frequently is pathogen definitions updated. Pathogen definitions also are defined (pardon the pun) as the basis of the antivirus solution during determining whether ones pc has been infected or not. So the far more updated is the antivirus tool, the higher the likelihood of preventing your computer from being infected. So think about this the the majority important aspect during selecting an antivirus program that could be updated regularly and quickly.

When I first started using my personal computer I really bought the Norton program at a local electronics store. At the time it was the best software that I had renowned preparing to assist protect my PC. It was relatively inexpensive and though I did not really grasp the scope of personal computer security, it was explained really thoroughly when I found out how to contact Norton antivirus.

You are to open emails that come from your family, friends or acquaintances. A good portion of viruses is ready to be downloaded from now emails from unknown sources coming different sorts of attachments. You also are not to open such emails. Rather go for an email filtration system that is going to put anonymous and spam loaded emails into the junk.

Of course I probably did not see the fine print getting ready having to pay to keep the antivirus program running, even but I found out the way to contact Norton antivirus and talked with the rep. Nonetheless it seemed that nobody made this transparent to me, even when I purchased the software from the store.

To build your personal computer faster, you actually may buy rid of a few those temporary files that you do not use anymore. Now files are also created each time you download something from the internet or install plans. This may down the method and you actually can also realize that it at the moment takes several seconds for it to begin. The installed programs is able to argument the method to slow down because there are some parts that continue to run across and this can burden the processor. To find the plans that run constantly, you have to press ctrl, alt and delete simultaneously on your keyboard. This will allow you to view the task manager where you will be ready to check for those programs and remove them to create your personal computer faster.

If you have a nice Audio and Video system setup in your home, you are fully aware that keeping good care of it and cleaning it correctly and consistently is vital to its longevity and performance. Keeping it free of fingerprints, dust, pet hairs and other harmful substances can be a real hassle; if done incorrectly it can even damage your system. Furthermore, not cleaning your system can lead to excessive dust and dirt build up that will harm the Audio and Video performance. It can even cause enough damage that you will have to replace certain parts. So below are some guidelines to walk you through keeping your audio and video system clean and performance ready.

Television

Televisions are usually the largest items in anyone’s home entertainment system. They also seem to attract the most dust. Of course build up of dust on ones TV screen is not ideal. Therefore, cleaning your Television seems to get top priority. Unfortunately, a great deal of damage can be done if the cleaning is not executed properly.

Most everyone is aware you must be extremely careful when trying to clean the screen of a LCD TV. Using regular cleaners will harm the screen, resulting in streaks and even discoloring on the screen. To clean your HDTV, whether it be a LCD or plasma, you can follow these guidelines:

- Power off your TV and unplug it from the power source.
- Wipe the screen very gentle with a soft dry cloth. Try to avoid too much contact with the TV screen. This is because a LCD screens have a specific kind of outer layering that can be damaged with too much contact. Never use a wet cloth or products like alcohol or thinner to clean the TV screen.
- There are commercially available cleaning sprays for LCD screens which are Alcohol & Ammonia free – you should spray these on a cloth or microfibre cloth first and then clean the screen with the dampen cloth.

- If it is not a LDC TV, but a rear-projection TV. You can clean the screen the same way as above, but it is fine to use a damp cloth.
- Other parts of the TV can also be cleaned using a soft dry cloth.

Blu-ray Players-DVD Players-Receivers

These items, even if they are tuck away or enclosed, can still build up significant amounts of dust that can cause damage, especially if the dust makes its way internally. Some people will only dust around or on top of these items, leaving the front buttons alone not to mention its collection of cables that build up large dust pockets.

The problem that arises is from the venting fans these items have because these fans circulate the air and cool down the Blu-ray and DVD Players. But the fans also inadvertently circulate the dust as well. If this dust gets into your system it will lead to many problems. In most cases prevention is your best weapon. Cleaning your items often and thoroughly will give them a greater lifespan, especially in optical laser items such as Blu-rays and DVD Players.

- Removing dust from the outer layers can be done with a soft cloth. You may want to use a touch of glass cleaner on the cloth since this will make collecting the dust easier. When dusting, try to start from the top down. When dusting around vent openings, push the dust away from the opening. This will avoid you pushing the dust into the component.

- Front panel buttons need to be given extra effort to clean. Try using a dry paintbrush to clean the buttons and knobs. This way you should avoid changing any settings.

- If you can not reach or find it hard reaching certain areas, try using a can of compressed air. Again be careful where you use it. You do not want to blow the dust into the interior of the component.

No matter how diligent you are in cleaning, there is always the possibility of dust or pet hair getting inside of your Blu-ray or DVD players. Because simply opening and closing of the loading tray dust can get into the component and cause problems, a good practice to adopt would be to always check a disc before inserting for dust, hairs or other substances.

Using an optical lens cleaner disc will help you clean the inside by getting rid of any dust or foreign substances. This disc will have tiny brushes or holes in the disc to create air currents to keep the lens clean.

It you believe dust has gotten into the interior of the component, beyond the optical lens, then your best course of action would be to take the item to a repair facility.

Cleaning cables can also be a little difficult. You do not want to disconnect anything or damage any connectors. Some ideas you may want to try are:

- If possible use the extension on a vacuum cleaner to get rid of the excess dust build up around your cables.
- Try using the dry paintbrush again around the connecting ports.
- Do not use excess force when dusting because you do not want to bend or crack any connector pins in your cables.
- Another good practice to adopt, is to disconnect your cable every year to see if the connection is clean and to look for erosion. If buildup is found, you will need to use a good contact cleaner to securely get the connection clean.

Speakers

Speakers usually have three different areas you need to keep clean: the cabinet, grille and the drivers.

Cabinets can come in different forms, whether it be a real wood veneer, a wood-like veneer, laminate material, plastic or metal – each one will need cleaning. Do not be tempted to use any type of household furniture sprays because they can damage the finish. It is best to use a soft dry or slightly dampened cloth.

Grilles are designed to keep dust away from the drivers. Therefore, an excessive amount of dust build up on the grille should be normal. It means they are doing their job. If the grille is fabric you may try using a vacuum to remove the dust. If the grille is removable, you can rinse them carefully in lukewarm water and dry them. If the grille is plastic or metal clean them with a dry or slightly dampened cloth. When using a dampened cloth be careful not to get the drivers wet. A can of compressed air can also be used.

Drivers should be touched as sparingly as possible. Your best option is to use a can of compressed air to remove dust from your drivers.

Always remember to power off and unplug electrical equipment you are cleaning. And refer to your instruction guide for details to clean a specific item. Manufacturers know their products and will give you good cleaning advice. Use the advice you are given because cleaning every item in your Home Entertainment System will definitely increase its lifespan and keep the high quality of performance you are accustomed to receiving from your system for years to come.

Duty on LCD/Plasma TV

The answer is yes. According to Bill Watterson, author of Calvin and Hobbes, “The problem with the future is that it keeps turning into the present.” Businesses are well aware of mobile phones’ potential for wireless marketing, advertising, sales, and payments although many thought this potential would be realized somewhere down the road. But it seems like that future is now here.

Critical Mass

Almost a third of North Americans now say they could not live without their cell phone and these devices are rapidly evolving into more than a mere portable tool for voice communications. According to a recent study [AP 2006] Americans have become addicted to their cell phones, with four out of 10 adults aged 18 to 29 considering dropping their landline service. In fact, almost a third (29%) say they could not live without their cell phone. The mobile has reached critical mass.

Thirty-five percent of those surveyed say they send SMS text messages, including 65% of those ages 18-29 and 37% of those aged 30-49. At the same time, 18% say they have used or would like to use a mobile instant messaging service on their cell phone. Meanwhile, 38% say they would like to have desktop IMs from select contacts automatically forwarded to their mobile device, including 50% of those ages 18-29.

In terms of “must-have” features when buying a new handset, the top-runners are: mobile maps (51%), text messaging (48%), and a built-in camera (47%) top the list, followed by games (34%), mobile email (32%), and mobile search (31%).

New Applications

The new .MOBI top level domain is expected to eliminate some basic problems associated with mobile browsing of ordinary Web sites, including large graphics and multimedia content. The new standards will ensure content works for Web browsing, mobile messaging, and device compliance on mobile devices. [Sullivan 2006]

Internet access via mobile phones is actually outpacing wireless access from a notebook PC in many countries with 56% of global mobile phone users browsing the Internet or downloading email in 2005. In Japan 92% of users went online via their mobiles. Rates are high in France and UK as well but flattening in North America. [eMarketer 2006]

About 20% of mobile phone users are already receptive to relevant advertising, if done correctly. Apparently understanding the trade-off of ads for services, over a third of users said they would also be willing to provide advertisers some personal information. [Burns 2005]

Podcasting and cell phones already offer a powerful synergy. Recently Mobilcast announced that it will help NPR deliver 45 of its podcasts to mobile phone users. NPR has had nearly 18 million downloads of its podcasts since its launch at the end of August 2005. [NPR 2006]

Mobile Video

According to an eMarketer report, This is the year that carriers, content providers and marketers are sitting up, taking notice and starting to experiment and invest in mobile television initiatives.
JupiterResearch also finds that the mobile video market is expected to grow by roughly eight times its 2005 revenue size by the end of the decade. In 2005 revenues from mobile video content reached $62 million. By 2010, the number is expected to reach $501 million. [Burns 2006]

From a technical point-of-view, the two key developments for mobile TV are growth in smartphones and growth of advanced 3G networks. Although adoption has been slow to date, these will move mobile TV past the pilot stage toward critical mass and finally to mass-market penetration.

A new study from London-based research company Red Bee Media and British digital media research agency iBurbia indicates that consumers will pay for video they value and are also willing to accept some advertising. [Video Content 2006]

But already “consumer interest bodes well for the mobile industry as vendors use different business models to try and tap into this consumer demand,” said Julie Ask, Research Director at JupiterResearch. “The challenge is not interest but rather finding the correct mix of premium content and price points.” In the longer term, adoption is expected to depend more on business models and content offerings than on the technology or devices, [JupiterResearch 2006]

Keitai Culture

We may be only a hop-skip-and-jump away from something the Japanese know all about already–keitai culture. There’s more to it than just owning a fancy cell phone.

Mobile communications have become part of popular culture and everyday behavior for many Japanese. With over 72% penetration, most everyone between the ages of 12 and 50 (89 million) has a mobile phone. This may provide a proactive glimpse of our own future. “By understanding how a once-alien technology became such a natural extension of everyday life in Japan, we may yet understand what is in store for the rest of the world.” [Jardin 2005]

As personal network keys, keitai open doors to other media such as audio and video. They also function as remote controls, letting owners change television channels or operate DVD players. Five million Japanese now subscribe to TV guides on their phones and Sony is offering a hard disk recorder that can be programmed remotely by cell phone.

Cell phones open doors in other ways too: “The embedded circuitry in newer mobiles, once programmed, also authorizes entry through corporate security doors and functions as an electronic key for some homes. Once a child returns from school and flashes the phone over a reader, the phone opens the door and automatically sends an email to the parent reporting his or her arrival.” [Johnson 2006]

Future Present

Keitai culture is the present in Japan but all signs suggest that it’s our rapidly developing future–and entrepreneurs need to think ahead.

Considering the growing critical mass, new standards, and expanding applications for cell phones, small businesses can no longer afford to ignore their potential for marketing, advertising, sales, and payments. This is especially true in the case of Web-based businesses–since mobiles increasingly appear less a device just to make phone calls with and more a general information, content, and Internet appliance.

Environmental Threats and Their Costs

The most common environmental threats to server rooms are temperature, humidity, water leaks, human error, intrusion, vibration, and power outage. Many of these threats, such as temperature and humidity, are related, which complicates environment monitoring and heightens the need for an automated, sophisticated system.

Temperature

Temperature is the main environmental threat to computer hardware. The generally accepted, ideal temperature is between 68 and 74 degrees Fahrenheit (20 to 24 degrees Celsius).

Excessive heat degrades network performance and causes downtime. As the temperature increases, a heat sinks fan works harder to cool the central processing unit (CPU). Continuous overworking causes the fan to fail, leading to a machine overheating. A machine shuts down when it reaches an unsafe temperature in order to prevent permanent damage. An administrator must then be located, day or night, go to the machine, and reboot it after it has cooled. Consequently, services hosted by a down machine are unavailable until it is restarted, which can take minutes or hours. If the server hosts critical services (e.g., e-commerce, user validation, email) that are not distributed to backup servers, revenues can be lost, users cannot login, and communications are interrupted. If the shut down is not done properly, data can be lost.

Excessive heat and rapid temperature changes also damage equipment. Rapid temperature increases can increase humidity, while rapid drops can cause water in humid air to condense on equipment. Together, heat and moisture accelerate the break down of materials used in microchips, motherboards, and hard drives, which is called premature aging. In worst cases, a machine won’t shut down when the temperature exceeds safe levels, and circuits are damaged. Ultimately, heat-damaged equipment must be replaced, increasing the cost of network maintenance.

Controlling temperature is becoming more important and more difficult because of changes in equipment design and greater use of network services. New equipment runs hotter because it runs faster and does more work. Also, more circuits are placed closer and closer together, trapping heat in a smaller space. Smaller equipment also means that more equipment can be placed in the same space, usually packed tighter together. The increase in density of equipment causes a rise in the amount of heat dissipating in a rack cabinet. Increased network usage also increases heat, so as usage levels change during the day, so does the temperature and the need for cooling. For networks that operate near capacity 24 hours a day, every day of the year, there is little, if any, time for machines to cool down.

Humidity

When the temperature is between 68 and 74 degrees Fahrenheit (20 to 24 degrees Celsius), the relative humidity (i.e., the amount of water in the air) should be between 40% and 50%.

A high humidity level can produce the following problems in the server room:

  • Condensation — Condensation occurs when humidity levels are too high or when there is a rapid temperature drop. Water that condensates inside equipment causes rust, short circuits, or deposits of dirt and minerals that corrode equipment. Moisture absorbing circuit boards expand and contract with changes in relative humidity levels. Expansion and contraction of these boards can break microelectronic circuits and edge connectors. Finally, condensation increases heat levels. Deposits of dirt and minerals act like insulation that traps heat in equipment and prevents it from diffusing into the air.
  • Fungus — Persistent humidity levels above 60% and elevated temperatures promote the growth of fungi. These contaminate the air with dirt and spores, which clog a machine’s airflow and promote heat retention and condensation. They also retain moisture and promote corrosion, which damage circuits and motherboards. Some fungi “eat” textile plastics (e.g., polyester) and PVCs, a phenomenon in which fungi breakdown the material used in these items. Most electronic equipment has some PVC materials, such as the PVC insulation used in cabling.

A persistent low humidity level can produce the following problems:

  • ESD — Electrostatic discharge (ESD) occurs in dry environments because there is not enough water to neutralize the charge buildup. ESD intermittently interferes with hardware and can cause system damage or temporary malfunctions.
  • Plastic Breakdown — Some plastics breakdown in low humidity environments, which is another form of premature aging.

Water Leaks

Proper planning moves equipment away from water pipes that might burst, basements that might flood, or roofs that might leak. However, there are other water leaks that are more difficult to recognize and detect. Blocked ventilation systems can cause condensation if warm, moist air is not removed quickly. If vents are located above or behind machines, condensation can form small puddles that no one sees. Standalone air conditioners are especially vulnerable to water leaks if condensation is not properly removed. Even small amounts of water near air intakes raise humidity levels and fill servers with moisture.

In addition, water from small pipe leaks can travel for long distances behind walls and continue for a long time before anyone notices it. Server rooms with raised floors are particularly vulnerable. All of the cables and wires for an entire network are concealed beneath floor panels. While this approach keeps cords safe from being accidentally unplugged, it makes monitoring their physical status difficult. Cables may be soaking in water for a long period before anyone notices. This situation breaks down insulation, and the loss of insulation causes signal leakage and performance degradation.

Human Error

Administrators/personnel can unknowingly create environment problems in server rooms by:

  • Adjusting the heat or air conditioning while working in the server room and forgetting to reset it when they leave
  • Placing boxes in front of vents “temporarily” and forgetting to move them, which blocks airflow
  • Moving equipment, which changes the room’s airflow and causes hotspots
  • Bumping equipment, which changes the direction of vent baffles and causes the exhaust of one machine to blow at the intake of another machine
  • Installing new equipment, unaware that it creates more heat than the old equipment
  • Failing to put blank panels behind empty rack shelves, which inhibits air from flowing up.

Similarly, cleaning crews sometimes close doors that should be left open for ventilation, thus increasing the temperature and reducing airflow.

Intrusion

Intruders, such as disgruntled employees and industrial spies, often strike at the most critical yet vulnerable points: the physical devices that store and control access to data. The small and delicate nature of modern computing equipment makes it easy to damage or steal; hard drives are compact enough to carry out in a briefcase, backpack, coat pocket, or purse.

Less sinister, but just as potentially harmful, are animal intrusions. Rodents, insects, birds and even larger animals have found their way into highly sensitive areas to wreak havoc upon equipment. Tiny contaminants, such as fur, dust, and dander, can cause component failure. Mice and rats chew through cable.

Vibration

Too much movement loosens connections within the server housing unseating boards and chips.

Vibration can also damage the hard drive disk, which rotates at extremely high speeds. Being bumped or moved can cause the platter, where the information is stored, and the head, which reads the information, to physically connect, causing scratches that permanently harm the disk drive.

Generally, vibration comes from mundane sources: being too close to halls or walkways, or being moved or bumped. Good space planning can keep shocks to a minimum, but IT staff should still monitor the situation. Some vibrations, such as those generated by a failing air conditioner, actually serve as warnings. Most machines vibrate more as performance worsens, so tracking fluctuations in equipment vibration becomes an important means to predicting failures.

Power Outage

Power outages, “brown outs,” and voltage dips and spikes represent big problems for computing equipment. A simple hiccup in power levels, let alone a lightning strike, can cause servers to fail. In best-case scenarios, this costs precious time before rebooting. In worst-case scenarios, circuitry is irreparably damaged and must be replaced.

Weaknesses of Current Monitoring Practices

In a typical business, three groups monitor the environment: network administrators, security personnel, and facility maintenance employees. Network administrators often rely on a single thermometer and subjective notions about “comfort” to control the temperature of server rooms and data centers. In addition, security personnel and facility maintenance departments monitor areas outside of the server rooms. These three groups usually attempt to coordinate their efforts, but they maintain separate systems and practices. Ultimately, network administrators are primarily responsible for protecting hardware.

This approach has the following weaknesses:

  • Not recognizing all threats – Damage caused by the environment can be subtle, unseen, or attributed to other causes. Accelerated equipment aging due to heat or condensation occurs over years and is often written off as a natural process (i.e., “equipment just wears out”). Condensation, rust, and heat damage is usually hidden inside machines, out of administrators’ sight.
  • Inconsistency – Administrators check room thermometers only when the environment feels hot or cold to them. Unfortunately, the sense of a “comfortable” temperature and humidity level varies from person to person, so problems are not always recognized.
  • Gaps in monitoring – Environment threats occur 24 hours a day, seven days a week. But administrators are not always in the equipment room, especially on nights and weekends. Depending on staffing levels and schedules, server room environments can be unmonitored up to seventy percent of the time during an average week.
  • Responsibility gaps – Another gap occurs because of shared responsibility. Water leaks and intrusion are monitored by maintenance personnel, security officers, and network administration. Frequently, one group will not monitor an area because it thinks another group already controls that area. Or one group will detect an incident but fail to inform all of the other groups. Consequently, vulnerabilities develop and potential problems are never investigated until it is too late.
  • Inability to track environmental changes – Temperature and humidity levels constantly increase and decrease. Without a log of conditions, administrators cannot identify problems caused by these changes. Often, these problems continue for days or months, while time and money is wasted investigating false causes and solutions.
  • Focus on catastrophes, not daily problems – Current practices avoid catastrophes, such as broken water pipes or power outages that shut down air conditioning systems. But they do little to protect from threats that slowly damage hardware or promote preventative maintenance, such as detecting gradual temperature increases that indicate a need to clean fans or air filters.

An effective server environment monitoring system addresses the weaknesses in the current practice of having personnel monitor the environment.

ENVIROMUX Server Environment Monitoring Solutions

NTI offers two server environment monitoring solutions, the ENVIROMUX-SEMS-16 and ENVIROMUX-MINI. Both units monitor critical environmental conditions (such as temperature, humidity, and water leakage) that could destroy network components in a server room. When a sensor exceeds a configurable threshold, the system will notify the selected administrators/staff via email, SNMP traps, Web-page alerts and a visual indicator (LED). The systems connect to your IP network, so they can be configured and monitored from any workstation with a Web browser.

Both systems provide the following benefits:

  • Control costs – In a stable environment, equipment lasts longer, and less equipment is damaged and needs replaced. Typically, the savings from not having to replace equipment can pay for the cost of the monitoring system.
  • Increase lead-time to fix a problem – The earlier the warning alarm sounds, the sooner personnel can solve the problem before it becomes a disaster. For example, a leak, if caught early, will not turn into a flood.
  • Reduce downtime – Hardware housed at the recommended environmental conditions operates more efficiently, while also shutting down less frequently. Consequently, employees stay productive, and e-commerce sites continue to generate revenue.
  • Log environmental data for greater insight – In order to maintain stable conditions in the server room, administrators must have accurate records of what has happened. Logging is also critical for investigating problems.
