Taking the Quantum Leap
While it may seem that the evolution of computers is about at its end, that is not the case. The next generation of computers is quantum computers. The reason behind continuing computer evolution is the continuing thirst we have for speed and capacity of our computers. Way back in 1947 an engineer and computing expert, Howard Aiken, predicted that all the United States need to satisfy its need for computers were six digital electronic computers. Other scientists and engineers that followed Aiken added to the volume they predicted as being adequately massive, but were also far too conservative.
What none were able to predict that scientific research would produce voluminous quantities of knowledge that needed to be computed and stored, nor did they predict the popularity of personal computers, and the existence of the Internet. In fact, it’s hard to predict if humankind will ever be satisfied with its computer power and volume.
A basic computer premise, called Moore’s Law, says that the number of a microprocessor’s transistors doubles every 18 months and will continue to do so. What this means is that by no later than 2030 the number of microprocessor circuits found in computers will be astronomically high. This will lead to the creation of quantum computers, whose design will use the power of molecules and atoms for processing and memory tasks.
Quantum computers should be able to perform specific calculations billions of times more quickly than can the current computers that are based on silicon. Quantum computers do exist today, though few and they’re all in the hands of scientists and scientific organizations. They are not for practical and common use – that is still many years away. The theory of quantum computers was developed in 1981 by Paul Benioff, a physicist with the Argonne National Laboratory.
Benioff theorized going beyond the Turing Theory to a Turing machine with quantum capabilities. Alan Turing created the Turing machine around 1935. This machine was made up of a tape whose length was unlimited and which he divided into small squares. Each square either held the symbol one or the symbol zero, or no symbol at all. He then created a reading-writing device that could read these zero and one symbols, which in turn gave these machines – the early computers – the instructions that initiated specific programs. Benioff took this to the quantum level, saying that the reading-writing head and the tape would both exist in a quantum state
What this would mean is that those tape symbols one or zero could exist in a superposition that could be one and zero at the same time, or somewhere in between. Because of this the quantum Turing machine, in contrast to the standard Turing machine, could perform several calculations at once. The standard Turing machine concept is what runs today’s silicon-based computers. In contrast, quantum computers encode computer information as quantum bits, called qubits. These qubits actually represent atoms that work together to act as a processor and as the computer’s memory.
This ability to run multiple computations at one, and to contain several states at the same time, is what gives quantum computers the potential to be millions of times as powerful as today’s best supercomputers. Quantum computers that have 30 qubits would, for example, have processing power equal to today’s computers that run at a speed of 10 teraflops (trillions of operations per second.) To put this in perspective, the typical computer of today runs at gigaflop speeds (billions of operations per second. As our cry for more speed and more power from our computers continues, quantum computers are predicted to be a readily available product sometime in the not so distant future.

Windows XP Tips for Computer Security
Here are a couple of tips to speed up your Windows XP computer and help keep you protected and secure online. First you need to control which programs load on startup: Many of the programs you install on your computer automatically configure themselves to launch at startup, usually invisibly. The truly essential ones, such as anti-virus and firewall products, generally run as services and run fine in the background. Other less important software like media players don't need to be running continually. These extra programs slow the boot process and then severely suck up resources like memory and CPU cycles. It is pretty easy to control which applications launch on startup. The System Configuration Utility lists all these applications in one place:
1) To get there: Click the ‘Start' button then choose the ‘Run' command.
2) In the text box type "msconfig". - Across the top of the dialog box select the ‘Startup' tab.
3) The Startup Tab lists all the programs that launch at start-up. To disable any of these simply un-check the box on the left. Only non-essential programs are listed here it should be safe to un-check pretty much anything. If it turns out you needed it just go back and re-check it.
4) Once you are done re-boot the machine.
5) When the Desktop returns you will be presented with a window that says you have chosen Selective Startup. Just Check "Do not show this window again" and click OK. To keep your computer secure, turn on automatic updates. Seems like every virus writer has nothing better to do then attack Windows operating systems. Keeping the system patches and security fixes is critical.
During the setup of XP Service Pack 2 with a new computer or an up-grade you are asked whether or not to turn on automatic updates, if you made the mistake of checking no you can find this option in the Windows Security Center (Start / Control Panel) and change it back. Even with all its faults, XP is a powerful operating system that has many good security features. Here are some more tips to help you get the most out of your operating system. Remove Windows components not found in ADD / REMOVE. Many Windows components, things like Network Services or Solitaire are easy to remove through the Add or Remove programs configuration window (Start / ControlPanel / Add and Remove Programs / Windows Components). Simply un-check them, but … some things are deliberately hidden.
A good example would be MSN Messenger. To remove this from startup follow these steps:
1) In Windows Explorer (right click Start / Explore), navigate to C:WindowsInf and make a copy of Sysoc.inf.
2)click on Sysoc.inf and it will open in Notepad.
3) Press Ctrl H (opens Find and Replace) and replace the string ,hide, with ,, then save and replace the file. Now all the hidden components will appear.
4) Then follow the steps above for removing programs from the startup menu. To restore a corrupted system file: If a necessary system file should become missing or corrupted by a virus you can replace it from your Windows CD.
1) Go to Start / Search and type in the file name replacing the last letter with an underscore (ex. Filename.ex_).
2) If the file is found, open a command prompt (Start / Run, type CMD in the textbox).
3) At the prompt type expand followed by the full pathname of the file and destination (expand D:Windowsfilename.ex_ C:Windowsfilename.exe) where D: is the letter of your disc drive. If either pathname contains spaces surround the entire pathname with double quotes.
If the file isn't found search again using the un-modified file name, it is probably in a CAB file, Windows treats these as folders, simply drag the new folder to the destination while holding down the right mouse button then select Copy Here.
1) To get there: Click the ‘Start' button then choose the ‘Run' command.

Ways To Hide Files On Your Computer
At some point in time, perhaps on your family computer, or your own computer, you will develop, collect, and store some important personal files on your hard drive that are strictly for your needs and purposes. These digital files may be so important to you, that under no circumstances, should anyone ever be able to access and see them. Some of these personal and business files may include documents, spreadsheets, emails, pdfs, text files, invoices, pictures, videos, and mp3s. These files may be so sensitive in nature, that you realize a need to prevent your spouse, kids, friends, or anyone for that matter, from viewing and accessing them. Perhaps, you may even need to hide porn or other explicit files.
Just imagine if your spouse, or little ones at home, did a file search for all picture files and movies that were on your computer. Hopefully the results wouldn't expose them to anything that you wouldn't want them to see. Just imagine what could happen, if your children at home decided to fool around with your work and files that was listed in the recent documents menu. Ok, you get the point. And thus, this question is raised: How do I hide files and folders so that they won't be discovered? There are several ways in which you can hide files:
You can put your files within a folder and apply the hidden attribute to the folder. You can bury your files deeply in subdirectories within subdirectories and hope that no one browses using Windows Explorer. You can change the file name and file extension of your file to something unique and strange, so that no one recognizes it, or you can purchase a file hiding software security application such as a folder lock or folder hider with password protection. All of the above methods may be your solution to hide your important files. It simply depends on the significant importance of your files and level of security you need.
You can apply the hidden attribute to a folder or file by choosing to do so within its properties. This is a simple way of hiding a folder in Windows XP. However, the files will still show up if a user sets the option "show hidden files and folders" within the folders options. Another way to hide a file is simply by concealing it by dumping it into a folder you think no one will ever access. However, you run the risk of it appearing within the results of a Windows Search and having it displayed in the documents list. Another way to hide a file is by renaming it along with its file extension so that no one recognizes it or is able to open it using its standard program. Although this method could possibly work for you, you would have to waste time renaming it and changing it back to the correct extension. And thus, the following question is raised: What is a quick and sure proof way to hide files in windows so that they won't appear within Windows Explorer and won't be displayed in the results of a Windows search? Your solution: A simple and easy to use folder security software utility that will allow you to hide files and folders and make them reappear all with a simple hotkey.
Supreme Folder Hider is such a solution that will save you time and will provide you with an extra added sense of security. Supreme Folder Hider prevents all file access from Windows Explorer, the command prompt, shortcuts, and most recently used document lists.

The Essentials of Software Testing - What Everyone Must Know about Computer Software Testing
Since we are living in a highly-technological age, the term computer software is not really new to us. They are basically found in a majority of electronic gadgets that we commonly see or utilize: from the computers that we use for the internet to the system applications that make basic machineries operate. Indeed, their emergence to our society has revolutionized the way we live our lives and it is because of this that future prospects are being cast regarding the growing demand of computer software in the future. So what then is software testing? Just like any other products that we see that are being circulated around the market, each of these products need to pass a certain qualification or standard before being made available for public use. Similarly, that’s what software testing does. It ensures that a software program passes a certain standard or quality as determined by professional computer testing experts before it is used by programmers to operate applications, gadgets and other computer systems.
For us to understand the whole process better, software testing can be summarized into three processes: verification, error detection and validation. Let’s take a look at each process step. Verification, from the root word verify, refers to the step of validating or verifying the capabilities and qualities of the software that is developed to see if it passes or reaches the desired standards or requirements before considering it for general use. But what if the software and its parts suddenly go wrong?
Now that’s where the process of error detection comes in. This step will subject the specific software program to a series of tests where it is expected to fail under normal circumstances. Of course, if it withstands those series of tests without failing the required standards, then it is approved. The final test that it needs to hurdle is the validation step, which requires the software program to perform the tasks or services it was made for.
And if the software program successfully hurdles all these three steps, it will then be subjected to a final series of test application to determine its suitability for higher-end technological services. So in other words, the software program will stage a successful run among all of these tests, then it will now be used for general distribution and usage. What are the implications of software testing to our society?
Well, people might find this technological process complicated but actually, it can potentially help and save our environment from future damages that abused technologies can bring. Software testing enables testing experts to determine at the initial stage the probable factors that can cause technological system damage to particular software programs and its possible adverse affects if misused in the long run. Overall, it will help experts generate data or facts that will help them improve on their researches on the field of computer technology in order to produce more innovative and technologically-beneficial products in the future.

How Safe Is Your Computer ?
Your computer can be open to attack from different types of spyware. Spyware constitutes those programs that are deliberately lodged in your computer without your approval or knowledge. The only way to escape spyware or at least minimize its effects is to install antispyware software on your pc. If you surf the web, you can be sure that you face the ongoing risk of spyware or adware. It is time you updated your antispyware programs to keep your PC healthy.
But first let us briefly examine the most common types of spyware. Gone are the days when viruses were expected only via our email. Now we don't even have to click a link to be infected. All we have to do is browse the Internet, and it's an open invitation to spyware. Spyware constitutes those programs that are deliberately lodged in your computer without your approval or knowledge. You can never live without spyware and adware protection.
Types Of Spyware
Adware is the worst form of spyware. These programs lay in wait for you to connect to the Internet and then they send you popups that give you all kinds of offers. And while you are thinking how considerate those websites are, these fake popups are actually recording your viewing habits and smuggling them off to marketing companies who sell you junk. Another irritating form of spyware is the browser hijacker. After installing themselves on your PC, they just change your default homepage and search engine. When you start your web browser, you'll find that you are flooded with ads, porn and other stuff you don't want.
The scary part of this is that they mine data - which means they report your surfing habits to someone who uses the information unethically. Keyboard loggers are thieves who steal your PIN number when you bank online. They get your passwords. This means, without spyware protection, your personal information and assets can be stolen. Then there are Diallers that enter your PC through a virus infection, adult websites, warez, or even MP3s. A dialler is software that dials numbers at premium rates when you are not around and you end up with bills for thousands of dollars.
If you use file-sharing programs, while installing it, spyware also gets installed, unless you read your end user agreements carefully or have antispyware software installed to keep these Trojans away. Imagine having every keystroke recorded, and your private instant messages, emails and other conversations being logged and reported elsewhere without you knowing about it! No - not the best situation to be in! So, never be without spyware protection.
Is There Freedom From Spyware?
The only way to escape spyware or at least minimize its effects is to install antispyware software on your pc. Some programs just remove the spyware but cannot prevent new spyware from coming into your pc. Get firewall software, if you use broadband or high-speed connections. Avoid clicking on links that promise you free movies, prizes, free software etc. Update your antispyware program and scan your PC regularly.

Effects Of Spyware On The Computer
Spyware has a lot of side effects of the registry. One of the greatest drawbacks is the slowing down of the system. This process will continue until the registry is cleaned with a registry cleaner. If you have browsed the Internet for a substantial number of hours it is guaranteed that you have downloaded some sort of Spyware to your system, albeit inadvertently. That is the reason it is called Spyware. If it made itself known it would not be spying. Spyware is not illegal software. It is downloaded with the 'permission' of the user. Once the Spyware downloads and installs itself it begins, first of all, to consolidate itself on the machine. It does this by entering its information in multiple parts of the registry. These entries can only be removed with Spyware removal utilities and there are many free anti Spyware and Adware removal tools available to do a satisfactory job for you.
Effects On The Registry
A lot of add-on Internet Explorer tool bars are also Spyware. They constantly monitor the users browsing habits and the type of software that is installed and run on the computer. At times this may be helpful to the user as the relevant advertisements are directed to the browser. However, in the long run this Spyware will definitely slow down the system to a crawl. This malicious software must be removed from the system as soon as possible with free Adware and Spyware removal tools. Spyware is constantly making entries to the registry. This makes the registry grow out of proportion. Since the system has to refer to the registry multiple times in a session, the registry has to be scanned from the beginning every time. Considering that the registry has tens of thousands of records it may take a very long time to scan and locate the information being sought.
Spyware keeps adding junk to the registry and this slows the system down. Removal Technique Spyware can be removed from the Computer with the use of anti-Spyware utilities. However, these utilities will only uninstall the Spyware from the operating system. The anti-Spyware utilities are not designed to go in to the registry hives and make changes. Going into the registry and removing the entries is very specialized operations and cannot be clubbed with some other software or program. Removing the Spyware entries from the registry is very important. Because once the Spyware determines that the exe file has been removed it will kick in from the registry and reinstall the exe from the Internet site it came from initially.
Therefore removing the entries with a registry cleaner is very important. Free Microsoft Spyware removal tools and PC registry Cleaner are good software that can remove all redundant and bad entries from the system registry. Qualities Of A Good Registry Cleaner A good free Spyware removal utility will have three facilities such as a registry backup function a restore function and a scan and repair function. It is important that the spyware cleaner make a good backup of the registry just in case the system fails to function properly after the computer clean up.
How To Correct A Continually Rebooting Computer
When you sit down at your computer desk and press the power switch on your desktop, the last thing you want to experience is a continually rebooting computer. There are a variety of causes that contribute to this problem, from something as simple as a stuck power button to a much more serious problem as your power supply slowly failing. Other causes for this problem may be overheating PC components, or viruses affecting your system.
Now, if you’re like the rest of us, having a computer that reboots constantly is not our idea of a productive day. So how do you diagnose this problem and where do you start to to make corrections. Here are some common but often overlooked causes and solutions that will get your system running again. First take a look at the power button and see if its stuck in the socket. If so, you may be able to simple tap the front of the case to release the button. In some cases, you may have to remove the system unit cover to get the button to return to the out position. If you cannot stop the computer from rebooting by pressing the power button and releasing it, turn off the power switch in the back of the computer next to the power supply.
If your power supply do not have a power switch, you will have to unplug the system from the wall outlet. This must be done as soon as possible so that the constant rebooting will not damage components such as the hard drive. Constant rebooting also have the danger of power surges that can further damage larger components such as the motherboard. Second you check your computer’s software by checking to be sure no virus or malware have not effected your hard drive.
Virus and malware are small software that is downloaded along with other files that is designed to cause mischief. To remove any viruses and malware, use a anti-virus program that will search your hard drive and remove these file quickly. These files can cause such damage as wiping your hard drive of all data or hijacking your web browser so you have no control over your online surfing.
If you find no malware on your computer, take a look at your BIOS to see if it has become unstable or has been changed. BIOS stands for Basic Input Output System and is a small program designed to check all components for proper operation when the computer is turned on. If your BIOS has been changed or if you’re not sure if its been changed, try to reset the BIOS settings to the default settings after you access the BIOS as the computer reboots.Once inside the BIOS, you should have the option to load your default settings, save the change, and reboot the computer.
However, there are times when a continually rebooting computer will not allow you to access the BIOS. You can then reset the BIOS by removing the system unit cover and locating the jumper on a three pin header. You must consult your computer or motherboard manual to properly perform this procedure and it should be done as a last resort. Before making any changes to your BIOS, you should backup your BIOS if your computer reboots at long intervals. After checking your computer’s software for its rebooting problem, you must check to be sure hardware is not at fault. This problem may exist because one of your memory modules are unseated from its socket .
Memory modules are long, narrow sticks that attach to the motherboard. Remove any static electricity from yourself, remove the system unit cover and check these memory modules to be sure they are secure.
Check the connections to the hard drive and the connections leading from the power supply. Power supply connectors should be checked if you’ve done work inside your computer recently. Power Supplies are known to slowly fail and lead to rebooting problems.
There is no way to check an ailing power supply and this should be considered the problem as a last resort. Following these steps will help you correct any computer that continually reboots itself. If no virus or malware is found, carefully and thoroughly check all connections. And if the problem still exist, the most likely cause would be the Power Supply

Today I am going to be talking about different ways you can make a computer run faster. There is actually a lot you can do yourself that will boost your PC's performance. So lets take a look at different ways we can remedy that slow computer of yours!
1. Free Up Disk Space
A great way to make a computer run faster is to free up some disk space. Windows comes with a disk cleanup tool that helps you free up space on your hard disk. The utility identifies files that you can safely delete without messing anything up, and then enables you to choose whether you want to delete some or all of the identified files. How to use disk cleanup tool.
* Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
* In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list. (If you have multiple hard drives you will have to select which one to scan.)
* Clear the check boxes for files that you don't want to delete, and then click OK.
* When prompted to confirm that you want to delete the specified files, click OK.
2. Use Defrag Tool When you add a file or a new program to a new computer, the hard drive is relatively empty so new data is saved to the hard drive in one whole block. When you need to use that information, the computer can quickly access it because it is all in one place. Defragging your system is definitely a way to make a computer run faster. How to use defrag tool.
* From the start menu point to "all programs"
* Point to "Accessories" to "System Tools"
* Click on "Disk Defragmenter"
* The disk defragmenter will display the hard drives on your computer. Just select and click Defragment.
3. Get rid of spyware Definition Spyware is software with malicious intent - by design; it does something bad to your computer. Usually, it gets installed without your knowledge. It sometimes takes advantage of the fact that most people click "I Agree" to software licenses without reading them. The only way to get rid of spyware is to have some kind of scanner, sort of like an anti-virus. In order to make a computer run faster and keep it safer your going to need an anti-spyware program. This is tricky, a lot of the spyware programs out there are malicious and will actually add viruses and spyware to your computer by using the "spyware scanner and blocker". So please remember to be very careful when choosing your anti-spyware program.
4. Find and repair disk errors Detect and Repair Disk Errors In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility. How to run the error checking utility.
* Click Start, and then click My Computer.
* In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
* In the Properties dialog box, click the Tools tab.
* Click the Check Now button.
* In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
* If bad sectors are found, choose to fix them.
Tip: Only select the Automatically fix file system errors check box if you think that your disk contains bad sectors.
5. Get an external hard drive Adding an External Hard Drive to your computer will allow you to clear out a lot of the things you don't need to be storing on your normal hard drive. A great example would be your music or pictures. All those songs and pictures are sitting on your computer making it go slower. You will see a decline in your computers performance as soon as you use over half of your hard drive space.
Moving all your songs or pictures to your external hard drive will free up a lot of space on your main hard drive. You can even move applications such as photoshop or games. An external hard drive is also handy because it is portable. You can unplug it from your computer and take it to a friends house and plug it in there, sharing photos and pictures very easily. This is truly a great way to make a computer run faster.

My Wife’s First (and Hopefully Last) Computer Virus
My wife came home from work the other day very upset. She works for a bank in the mortgage Department and they had given her a laptop for her use at work. Someone had sent her an e-mail that had an interesting sounding attachment, so she opened it. It wasn't long before things started to go wrong with her computer. Not only were there multiple pop-ups that were taking place all of the time but her computer had slowed to a crawl.
It seems that there were so many viruses and spyware programs running on her computer that it simply could not keep up with the load. All of this happened because of one Trojan horse virus that was opened on her computer that allowed all of these other things to happen. If it wasn't bad enough that she had the pop ups, they soon begin to become embarrassing.
Not only were they trying to sell her things, but many of the pop-ups were simply obscene material and pornographic advertisements. This certainly did not look good coming across on her computer all of the time, especially when she was dealing with mortgage clients. She was practically in tears by the time she had come home to ask me if there was anything that I could do.
The first thing that I did was to try to identify what they pop-up windows were and where they were originating from. It turns out that the particular spyware program on her computer was of the “Trojan Horse” variety, and was actually one of the more difficult ones to remove. Not only that, but the virus had really taken over a lot of her computer. We both feared that there was some keystroke logging going on in the background. I needed to get this computer clean from the Trojan horse virus and get it cleaned quickly. Because it was a computer that was associated with a bank I needed to get permission from their network guy to be able to log on to the internet from home. It turns out that most of the critical programs were actually run from a central server so there was not a problem with my doing that.
I ran a free program called Hijack This and posted the results to one of the many technical forums on the internet. (I trusted this particular forum, so I did not have any real concerns about privacy.) The technical forum gave me step-by-step instructions on how to clean the system from the Trojan horse virus and all of the spyware that it allowed to enter onto her computer. It took me several hours and I needed to go in and edit system files and the registry but I was finally able to win out over the virus and her computer was now clean. It doesn't matter where an e-mail is coming from.
It could come from your mother or someone else that you know and trust very much. If a Trojan horse virus is propagating on their system and sending itself out to others you will likely be a target of this virus as well. Never open anything that you are unsure of, and even if you are sure, run a virus scan on it first.

Used Computers (Desktops/Laptops)– What To Look For?
Nowadays desktops and laptops are much more durable and dependable that they were just five years ago. Therefore, buying a used or refurbished computer is becoming more of a trend. Suppliers replace their computers on average every 6 months and companies frequently upgrade their equipment. Buying one of these used or refurbished computers can save you a lot of money while still using a quite up to date technology. This is even more relevant if you are not a heavy user (i.e. most of your time on a computer is spent online, you may use a few standard applications once in a while). Even modestly priced computers will more than suffice for these types of demand.
Thinking about buying a used or refurbished desktop or laptop? Buying a computer is not at all an easy job, one has look get detailed information of the available computers of good and reputed brands. One must take into consideration the size, color, configurations, features etc… While your computer should correspond to your personality and lifestyle, you should always keep in mind the reputation of the brand in the market. Brand counts a lot; you can render good service by the manufacturer if your computer is damaged.
Important handy
Tips before buying a computer...
* Verify if the brand is reputed and always buy a good reputed brand. Read about customer service experience for that specific computer issues
* Check the warranty/guarantee of the computer (seek out computers which still have warranty/guarantee remaining)
* Compare the price of the new model in the market with what price your buying your used computer, try to get the best bargain. i.e. a two year old computer should not be bought for more than half of its original price.
*Check if the computer is outdated (if out of production it is difficult to get spare parts)
* Is the operating system current (Windows Vista/Windows Xp). Earlier versions probably run slower (windows 2000) and would not be advisable unless your needs are limited (i.e. web surfing, Word...). In any event, stay away with computers running on Windows 98 (granted you don't find many anymore). Also be aware of Windows Vista. Many users are reverting back to XP and that is even more obvious in the corporate world. Why? Vista looks nice but doesn't bring many technical improvements; therefore IT managers are not willing to implement something new when what they have works just fine. Some domestic users just don't like the new way of navigation within the Vista Operating System.
* Check if the configuration of the computer you are buying is good.
* Check the speed of the processor. If possible start the computer and see how long it takes to fully turn on. If its slow just turning on, imagine the lack of speed once you start adding software.. Additional Tips for laptops
* Is the battery life good? (search for the computers with a very good battery backup (2 hours minimum).
* Check for the screen size of the computer your buying and see to it that it is not exceeding the Normal (normally the screen size should be between 15-17). Less than that generally translates in older computers and increases the chance of age failure. Once the screen breaks, you are often better of changing the whole computer.
* Review the connectivity of the computer (Network, USB, Video, Audio…) look to it that it has a good connectivity including wireless
* Check out the weight. Ensure the computer is light enough for you to carry (light 7pounds) Where to buy used computers:
* Online auctions. Pro: Often offer the best prices. Cons: Cannot validate the accuracy of the described item. No warranty. Tip 1: Some companies will offer warranty for up to two years, the cost is about 12 of the purchase price. Tip2: Buy from sellers with great feedback, do not hesitate to contact the seller with questions prior to bidding
* Online marketplaces: Pro: Set prices and quantities - Sometime warranty is available. Cons: Prices can vary a lot, do your homework
* Craiglist.com Contacting sellers on Craiglist.com in your local area gives you a chance to meet with the owner and physically test the computer before the purchase Where to buy refurbished computers: Refurbished computers can be a great way to buy as they have warranties and are generally sold by manufacturers or companies affiliated with them.
* Manufacturers websites will tell you how to buy directly from them or from their authorized sellers. Pros: Warranty, established companies. Cons: Prices are higher than regular auctions (you pay more for peace of mind) Buying a used or refurbished computer can be a great way to save money. If you use some of the advice discussed above you can avoid many pitfalls. One last thing concerning laptops, make sure you have a good bag to protect your computer from a fatal accident. Your bag should be big enough for a 17 inch screen computer as it is rapidly becoming the norm, you will probably change your computer within a few years, the bag you may keep a lot longer. Good Buy!

How a Surge Protector Can Help a Laptop Computer
Electrical power spikes can be devastating to any electronic device, but the damage to a laptop computer can be even more significant to its owner because of the potential for lost information and reduced productivity. Safeguarding laptop computers with a surge protector (also called surge suppressors) is one simple and inexpensive way to lessen the risk of physical damage or lost information due to electrical surges. Fluctuations in electrical service are common around the world. Known as power spikes, surges, brownouts, and blackouts, these fluctuations can cause anything from fire to data loss in an unprotected laptop computer.
When power returns, it can come in a rush, rising significantly above standard household voltage levels to burn wires, overwhelm circuits and potentially cause damage to laptops, adapters, and any external peripherals that may be connected to the computer. Even when the power surge is not strong enough to knock out a system, it can slowly damage the computer's components, reducing its reliability and lifespan. A surge protector diverts the extra voltage from a power surge to a ground wire, sparing harm to any connected electrical devices. Most household appliances use 120- volt power (AC) - the level of electricity that you get from a regular electric outlet. Laptop computers covert 120- volt power to about 12 to 18 volts (DC) by way of an adapter that is usually located along the power cord. This conversion offers some measure of protection, but it never hurts to add the additional shield of a surge protector. Surge protectors are inexpensive insurance for costly electrical gear.
They also add functionality to most office environments, as they typically come in a power bar format that offers extra outlets. While most surge protectors are also power bars, not all power bars are surge protectors. Be sure to check whether surge protection is offered before purchasing a power bar. Power bars with surge protection may cost slightly more than a regular power bar. Many office environments use surge protectors as part of their standard equipment configurations. However, portability is a key feature of laptops, thanks to their small size and alternate battery power, so laptop operators often find themselves using their laptops outside of the surge protected office.
Ideally, laptops should be guarded by a surge protector wherever they are being plugged in, so a travel-size surge protector is a good investment. This is especially true in a hotel or large building where air conditioners, elevators or other equipment requires periodic bursts of large amounts of electrical power. Not all surge protectors offer the same level of protection, and none can guarantee electrical equipment won't be damaged if there is a severe power surge such as that caused by a nearby lightning strike.
A powerful surge may also damage the surge protector, so try to find a model with an indicator light that goes out if the unit fails to function properly. There are several Underwriters Laboratories (UL) ratings (found on the label) that can help you choose an appropriate surge protector, such as clamping voltage, energy absorption and dissipation, and response time. Clamping voltage is the point at which electricity is diverted to the ground wire. Look for 330 to 400 volts. Energy absorption and dissipation is the amount of energy, in joules, that the surge protector can handle before it fails. The higher the number the better. A rating of 200 to 400 joules is adequate, but a rating of 600 joules or more will offer superior protection. Response time is the delay between the power surge and the surge protector's diversion to ground. Faster is better, in this case, as the less time your laptop is exposed to the extra energy, the safer it will be. A response time of less than a nanosecond is desirable.
Power surge consumers who aren't knowledgeable about electricity and UL ratings can also judge a surge protector by its price: more expensive models tend to offer better protection than the cheapest discount store models. Quality laptop travel surge protectors can generally be purchased for less than $50 (USD), and offer a variety of features including telephone and network/broadband Ethernet jacks, and universal plugs and sockets that will work in countries with electric utilities offering 100 volt AC service to 240 volts AC service.
Some travel adapters have built- in surge protection that protects laptops as well as cell phones and personal digital assistant (PDA) devices. Most laptop surge protectors are designed with convenience in mind, and are compact and easy to pack. The last consideration in purchasing laptop surge protection is the quality of the warranty offered by the manufacturer. Some companies will offer compensation if equipment is damaged by a power surge while it is protected with a functioning surge protector, but warranties vary, so read the fine print.

One way to use your computer in a home business is through MLM or multi level marketing. This is an online earning opportunity that allows you to enjoy residual income sometime in the future. All you have to do is to invest a good percentage of your time and energy to the business now and you will definitely reap the rewards of the future.
There are a lot of MLM opportunities today. And by far, it is the easiest way to earn big bucks while surfing the internet. It works because of its structure. And that's where you are going to invest most of your resources. For those who still don't know, MLM is the process of promoting a product or a service and recruiting others to earn. Basically, you will earn two ways. Most MLM companies carry a product or a service.
These are the things you are set to promote. If in the market the product costs $50, you only get to purchase it at $40 or lower direct from the MLM company who distributes it. For every sale you make, you add $10 to your pocket. Now that part is called hard selling. A lot of people don't like to sell anything, whether it's online or face-to-face. For those who don't like selling at all, that's okay, because you can earn the other way.
And that would be through recruiting others to join under you. Between the two, this is the easier way to earn through MLM programs. All you have to do is to invite other people and that's it. You will be able to earn from their earnings as well. If your chosen MLM program has some sort of registration fee, then you will be paid for your every recruit. Some companies can pay for as much as $5 per downline or even more. Plus, if your downlines are able to sell a product, you'll earn from that too. Basically, you will be earning for the every activity your active downlines makes.
If they make money, you make money. So if you have a good number of them under you and they are really performing on their tasks, you really need not promote the products yourself. All you have to do is to wait for your check to arrive as you let them all do the working. Some MLM programs provide compensations to deep as three to four levels. This means that you can earn from your downline's downline too. The key to earning through this computer home based business is to choose the most lucrative program, invest some time and effort, and manage your downline so that you'll earn big while working less.

Drug Detox Demand May Be Reduced By New Computer Program
Most of the 500 Metro Detroit doctors who recently evaluated a new online prescription drug program say it improves patient safety and quality of care by reducing the number of pharmacy errors, patient allergies and harmful drug interactions that can occur as a result of hand-written prescriptions. This is good news for the thousands of victims of prescription drug problems who end up needing drug detox.
The majority of drug-related trips to emergency rooms and detox centers – not to mention sudden deaths and trips to the morgue – are caused by problems with prescription drugs. Hospitals, ERs and detox centers in recent years are seeing more dependencies, addictions, overdoses and life-threatening drug interactions as a result of prescription drugs than more traditional illicit street drugs like heroin, cocaine in its many forms, and perhaps methamphetamine.
Most drug detox facilities now provide specialized medical drug detox services for a host of different prescription drugs. And although detox centers help people with problems caused by legitimate prescriptions, many of the most commonly abused prescription drugs have found their way into the illicit street drug pipeline. And virtually all of the popular prescription drugs now found in schoolyards, night clubs and on the streets require drug detox to safely get off them.
The new prescription drug program, called ePrescription, is used by doctors right in their offices to access online information about a prescription drug, including generic alternatives, potentially harmful drug interactions, and potential allergic reactions. Patients already taking other prescription drugs often don’t remember what they’re taking or forget to tell the doctor about them – or the doctor doesn’t ask. But because the program lists all the patient’s medications, it helps avoid the serious side effects or even dependencies that lead to drug detox when the wrong drugs are combined. And because the doctor uses the computer to print out new prescriptions, it helps prevent patients from getting the wrong drug or wrong dosage just because a pharmacist couldn’t read the doctor’s handwriting.
In the two years that doctors have tested the program, 3.3 million prescriptions were written, and nearly a third of them – one million prescriptions – were identified as offering potentially harmful drug interactions, and another 100,000 prescriptions were spotted as being potentially allergic. In all, 423,000 prescriptions were corrected – changes that, if not corrected, might have caused injuries and even deaths. For drugs with a high potential for dependency such as narcotic painkillers and many antidepressants and antipsychotics, keeping track of the prescriptions with the computer surely helped prevent trips to drug detox.
The power of the new program to improve patient health and prevent prescription drug misadventure was lauded by most of the doctors testing it. They said it alerted them to potential problems they wouldn’t have noticed otherwise, and they liked how the program let them check other medicines patients were taking. Mixing prescriptions is always an area of risk that can precipitate dependency or addiction and lead to the need for drug detox or to complications and even death. Detroit’s new online prescription drug computer program appears to be helping get that city’s prescription drug error and abuse situation under control, and should help save a lot of people from needing a drug detox program.

Ecommerce And The Blue-Collar Peasants?
In medieval times the common laborer was thought to be less able to understand certain elements of civilized society. These men and women were not allowed to learn to read nor could they attend houses of worship because they were considered incapable of understanding what they heard.
Yes time after time these peasants were the basis for stories of renown and wonder. It is said that a peasant who listened to a sermon outside a church gathered bits and pieces of the Christmas story to write a carol that is still sung today. Even in recent memory there has been a prevailing thought that only certain individuals are capable of developing a business. This is usually linked to the social standing of the individual or to the accumulated wealth of his or her family.
In business success has typically been tied to who you are, who knows you and how deep your pockets are. If you didn’t have the ‘name’, if you weren’t recognized and you didn’t have much money then your business would likely fail. Ecommerce views every business owner as equal. There is no distinction and no preconceived ideas about the background or abilities of the business owner.
The link for all good online businesses is the ability to develop trust. If you are conscientious about providing exceptional customer service and superior products you may likely discover an improved customer base no matter what your personal background is like. A blue-collar worker with a big idea has every reason to believe they can succeed online. A hard working rancher can develop an idea from their land of wide-open spaces and it may succeed.
A single mom struggling to make ends meet might just come up with an idea that contains all the elements for a hit. Rules that have always seemed as if they are designed for the ‘haves’ and ‘have nots’ no longer seem valid in an online business environment. The role of cyberspace is to equalize the impact of business ideas.
How does it do that? In an online world you are going after customers on a global scale. You are no longer judged on your past failures or successes you are simply judged on your ability to deliver and provide quality products or services - now. If you can do that most customers would not even think to inquire about your lineage or stock portfolio. An online environment can be one of the least discriminating places on earth.
online presence is what speaks most to your product offerings and ability to fulfill your promises. So, in a barn in Utah, a kitchen in Harlem or a neighborhood garage in New Jersey there are likely online businesses that are being developed to improve the quality of life for families that have struggled long enough.
Perhaps the most interesting irony in this is that some of the customers who frequent these ‘great idea’ sites may be white-collar workers who are less interested in the dynamics of the online business and more interested in receiving what they need. Isn’t that what we all want in the businesses we trust?

Security And The Auto Complete Feature
The security of your computer is important on both private as well as business applications. Many have found the use of the auto complete features associated with many browsers a popular way to avoid keystrokes.
After all what could be more convenient than simply filling in a form for informational purposes and allow that saved information to be brought up with a single click? The auto complete feature is especially popular with email programs. You simply type a few letters related to the email address and if it is in your system you may receive multiple choices that include those letters. You choose the correct email address and click send. The process is quick and has found many appreciative users. Even word processors can use auto complete technology.
For instance if you begin to type today’s date you may find a suggested date that you simply click saving some typing time. Many have come to rely on the feature to make checkout in ecommerce quick and painless. I’d like to provide an argument for refraining from using some auto complete technology in the world of online business. The use of this technology in a word processor is generally a great tool simply because it does not rely on any personal data and is primarily designed to assist in popular words, dates and letter writing. However, when it comes to filling in a one-click web browser auto complete feature there are a couple of scenarios I’d like you to consider.
Barb owns a small, but growing online business. She hired Pam on a part time basis to help with product fulfillment. Pam was a good worker and was allowed to use the company computer from time to time. Without intending to do so Pam clicked a box that filled in auto complete data and she was able to view personal data that Barb might not have shared with Pam under other circumstances. Perhaps nothing ever happens with the data, but if Barb had to do it over again she may not have used auto complete. Brian is a hacker. He doesn’t consider himself malicious although his actions may say otherwise. He tries to find ways into other computers to explore the holes that may exist in a system. As he is exploring one afternoon he found a vulnerability in Barb’s computer security.
One of the pieces of data Brian may be looking for is to see if Barb has used an auto complete feature. He can gain plenty of information and has the potential to gain password information because Barb settled for convenience over caution. Barb would never have given out this information to just anyone, yet more than one person has access to her computer and this information was easily obtained.
businesses are also disabling the ability for their computers to store and remember passwords. If a site is accessed where a password is stored it becomes very easy for a third party to investigate online accounts, buying habits and potentially make an online purchase under your name and using your credit information. It may seem a small thing, but evaluating your use of auto complete technology may be an issue worth your attention.
