How to install the computer network efficiently.
Being wait-listed is tough, and you need the right set of keys to open the door to your dream program. The truth is that even with these keys, it's still not guaranteed that the lock will work. But this keychain has the critical pieces of metal you'll need to turn that lock.
First, a word of introduction: Realize that receiving a wait-list letter means you qualify for admission. You pass. You are probably on the wait-list (and not admitted) because they have already admitted applicants with your profile and want diversity in the class. Or they find your qualifications impressive, but find someone else's even more so.
Now let's examine that keychain. has become an essential prerequisite for any efficient modern-day business as it allows employees to truly work as a team by sharing information, accessing the same database and staying in touch constantly. For a computer network to give the best results, a lot of detailed planning and foresight is required before installation.
Firstly, an organisation needs to clearly define its requirements – how many people would use the network, how many would use it locally (within the office) and how many might require remote access (from a different location), how many computers and other devices (servers, printers, scanners) would be connected to the network, what are the needs of the various departments and who would be in charge of running/managing the network. It also helps if one can anticipate the direction the company would take in the near future so potential growth can be factored in during computer network installation.
The technology issues should also be ironed out in advance – hardware, software, servers, switches, back-up devices, cables and network operating systems. Make sure you have the required licenses to run the software on all your machines before installing a computer network. Alongside computer network installation should proceed ,the building of a dedicated technical support staff, either within your own organisation or outside consultants. Delegate responsibility clearly for network management. Before installing the network, you also need to choose the security mechanism to protect corporate data and keep viruses at bay.
The transition to a new or upgraded computer network can bring some teething problems. To minimise chances of confusion, the company might need to train its staff to make them familiar with the new system. Careful planning will to a large extent prevent crises like system downtime and network crashes.

Are computer viruses spread by the media?
If you believe what you hear in the media, there are an awful lot of viruses going around. No, I'm not talking about the make-you-sick kind of virus, though they get plenty of airtime, too. I'm talking about the kind of virus that enters via your internet connection rather than your nasal passages.
What the mainstream media often don't tell you--at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles-- is that many of these "viruses" are not viruses at all.
What Computer Viruses Really Are
The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, Trojans, and spyware.
So, what's the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware--worms, Trojans, and spyware--are usually only detectable with a special scan.
The Real Danger of Computer Viruses
If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what's to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else's.
Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine--after all, what would it benefit the worm to shut down its host computer?
Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan itself does no damage.
But even if you don't care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.
Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don't think you have personal or financial data on your computer? Some spyware programs contain a keylogger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the keylogger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.
Why Blame the Media?
Given the danger of all these different types of malware, isn't it a good thing that the mass media are becoming hysterical about it? And can't they be forgiven the sloppy reporting of calling Trojans, worms, spyware, and other malware "viruses"?
No, no, no.
This is a classic case of bad reporting doing more damage than no reporting at all. In this case, the damage bad reporting has done is to promote a common myth that goes something like this: "The only malicious software is a virus. Viruses damage your computer. Therefore, if my computer is working OK, my computer has no malicious software. I only need to scan my computer for problems when there is a sign of problems."
Thanks to this myth, many people complacently let their antivirus software go months out of date, not wanting to be bothered with scheduling an automatic update. Just as bad, many people don't have any extra software to combat the other types of malware that may not be covered by antivirus software.
In fact, it's not uncommon for people who have found malware on their computers after a scan to say, "but I never had malware on my computer before!" But how would they have known if they had never scanned!
Until the biggest mainstream media--and especially television--start educating the public about the need to have their computers automatically scanned at least daily, the world will continue to have major, drawn-out problems with malware that could have been wiped out as soon as soon as the anti-malware software makers discovered it.
And until that day, the mainstream media will have many more opportunities to run hysterical stories about "viruses," thereby forcing them to sell more newspapers and broadcast to even larger audiences of people who suck at the information trough yet somehow never become full.

7 Great Computer User Tips - For Windows® Users Only
An Easy Performance Enhancement
If you’re using the NTFS filing protocol on your system, instead of FAT32, you can get a bit more speed by disabling Windows® Indexing. The downside to this is that searching your drive for a specific file might take a moment or two longer, but everything else should run faster.
To disable this feature open My Computer and then right click on the drive you wish to reset – usually C-drive. Now click on Properties and then uncheck “Allow Indexing Service.” It will take Windows® a few moments to accomplish this task, based on your processor speed. If you have other hard drives, perform the same process for them. After this is done, it’s a good idea to empty the Recycle Bin and then Defragment your hard drive(s).
FREE Software
If you have a system and it does not have an office suite, such as Microsoft Office, and you don’t want to pay several hundred dollars to have one, try Open Office. This is a great alternative to other suites, and it’s free! Simply direct your browser to www.openoffice.org and follow the instructions for downloading and installation. Make no mistake, this free office suite is an extremely powerful set of software tools – easily a match for any competitor.
Internet Explorer (Microsoft’s Internet browser) is unarguably the standard in computers. This is why hackers develop so many malware applications to invade it. If you use a different browser, you have much less chance of an invasion by malicious software. There is a great alternative available, and it’s free. You can download a copy of Firefox at www.mozilla.org/products/firefox. You can even move your Internet Explorer settings into Firefox automatically – so you don’t lose your Favorites, etc.
Laptop Printer Fix
If you’re using a laptop that is running Windows® ME, and you’re having trouble printing through the USB, try this simple fix. Go to the website for the company that manufactures your printer. If you use a Hewlett-Packard, for example, go to www.HP.com and download the appropriate drivers and install them. ME has drivers that recognize the USB printer is present and attached, but not the drivers needed to make it print. Which drivers you download and install will be dependant on your printer. After installing new drivers, update the printer as necessary in the Control Panel.
Save $$$ When Shopping On-line
If you’re making a purchase on-line, and you know the item you want to buy, you can easily compare pricing all across the Internet. This can amount to a very substantial savings.
At this writing, I went to www.mysimon.com and typed in that I wanted to buy a printer: a Canon PIXMA iP4000. The service instantly checked the Internet and returned prices ranging from $62.00 up to $286.00. This kind of price spread is not at all unusual, especially for computers and electronics.
The My Simon website service only checks pricing, it does not provide a platform for purchasing anything, though it does link to such places. It also gives a rating for the sellers and other users’ input regarding their experiences with the company. You can order the results of the search for your product by price, so that you can quickly find the lowest price from the highest rated dealer.
Windows® XP Professional Only
A feature of Windows® XP Professional, that is not available in the Home Edition, is the ability to encrypt files. This encryption prevents others from opening the files in the folder you encrypt. To encrypt one or more a folders, follow these easy steps.
Click Start, then My Documents. Now locate the folder you wish to encrypt and right click on it and choose Properties.
On the General tab, click on Advanced. Put a tick mark in the box for Encrypt Contents to Secure Data. Click okay two times and the confirmation dialog box will appear allowing you to select the folder, the folder and all files, and/or the subfolders within it.
Now you'll be able to place files in this folder (or folders) and since they're encrypted, others will not be able to access them.
Internet Safety
You should never reveal your username or password to anyone who e-mails you and asks for it. This information is frequently asked for by an Internet scheme called “phishing.”
In a common phishing scam, you receive an e-mail that looks quite official. It usually appears to come from a bank or credit card company. A common title for these e-mails is “We need to verify your account information.” Another is “Please logon to your account and verify your settings.” If you do click where instructed, you’ll end up on a site that appears to be the real one. If you fill in the username and password for of your on-line banking account, you can expect serious problems within twenty-four hours.
If you believe that a company or business that you do on-line business with really does require your information, then simply contact them. This way, you will know where you are sending your information, and what it will be used for.
CD Burning Error Fix
Burning music, video, and data CDs has become quite popular over the past few years, and the evolution of the supporting technology has yielded hardware and software that is better than ever – and very reasonably priced. CDs offer a great place to store substantial amounts of data in a small, easily retained format. They also give us new control over aspects of our entertainment.
A relatively common error received during CD burning informs you that the CD cannot be burned, or that there was an error during burning. Of course, you could actually have a defective CD drive, but this is usually not the case.
If you receive a message indicating that your CD cannot be burned, go to the website of your CD drive manufacturer. Look for the list of CD types (manufacturers/numbers) that are compatible with your device. Most often, you’ll find that your CDs are not listed. The two types that seem to have the least difficulty being burned are manufactured by Sony and TDK. These cost a bit more, but they burn very reliably.
Along the same lines – H-P has introduced a new CD burner. This new burner requires the use of special CD blanks, but after you burn your data into the CD, you can flip it over and close the drive again. Then you can use the laser to burn a title for the CD directly onto the CD itself. It’s new technology, but perhaps it will catch on and we’ll see newer, better such devices in the near future.

3 Simple Ways To Save A Bunch Of Money When Buying A New Computer!
Looking to buy a new computer?
Overwhelmed by all of the options available to you?
Stressed by the high cost of computers today?
For most people, buying a new computer does not have to be as stressful as buying a new car. Nor does it have to be as expensive. If you’re like most people, and you have a limited budget for buying a computer, then you need to try to get as much computer for your money as possible.
Here are 3 simple ways anyone can save money when buying a new computer:
1) Shop around for best deal.
Sounds pretty obvious. But many people don’t realize they don’t need the fastest, most expensive computer with the most “extras”. In fact, if you are already using an older computer, even the least expensive new computer will be a big upgrade. If you don’t know a lot about computers, you can learn a lot by shopping around. Ask lots of questions, compare prices, compare features, then find the best price. Shop at your local electronics store, and look for the best deals online. You’ll be surprised at how much money you can save by shopping around!
2) Install your own “extras”
Many computers you will find in a store have a lot of extra software already installed. While this is convenient, it is not always the best way for you to save money. Also, while many of these extras sound good, you don’t always need them. You can often find better deals by shopping around separately for your own software extras (such as a word processor, anti-virus, popup blocker, spyware removal, games, etc). And some of these you can get for free. So before you buy the “fully loaded” computer, ask yourself if you really need all the extras, then shop around to see if you can buy a scaled down computer - and get the extras yourself for much less!
3) Don’t buy extended warranty
If you are not a computer “techie”, the extended warranties offered by the computer retailers often sound like a good idea. After all, who wants to be bothered paying for service on a computer after you buy it. But keep in mind that most computers come with a warranty, and most computer problems will either happen at the beginning (when you still have the warranty in effect) or much later (when it might be cheaper to buy a new computer). Technology changes very quickly these days. So consider whether or not it’s worth the inflated price of the extended warranty. And, if you really feel you need the extended warranty, then ask to purchase it at a lower price. Not all retailers will negotiate on the warranty, but some will. And whether you buy the extended warranty or not, make sure you back up all your files periodically, just in case!
If you have an unlimited budget, consider yourself lucky. And if you do business on the computer, make sure you get what you need, while trying to keep the price down. At any price, buying something that does not fit your needs is not a good deal.
Hope you find these tips helpful, and happy computer shopping!
