Care of Computer
After purchasing a computer, you definitely will want to take care of your investment.
With just a little care, your computer will continue to give you maximum performance. Here are some computer care tips:
Keep your computer away from direct sources of heat (like space heaters).
Do not eat or drink when you use your computer.
Clean the keyboard with a vacuum cleaner nozzle equipped with a brush tool, and periodically clean the air vents on the side and back of the monitor with the vacuum brush.
Turn the monitor off to clean it, and use only a soft cloth with no soaps or chemicals.
To help keep the keyboard clean, wash your hands before using the computer. When dirty, wipe the keyboard keys with a soft cloth, moistened with a mild cleanser.
Dust and cobwebs can accumulate in the CPU case. Once a year, remove the case cover. If there is an accumulation of dust and cobwebs, use a can of compressed air to blast the debris away. Be careful, however, not to poke and prod the computer's internal components! Static discharges can destroy sensitive electronic components.
Invest in a good quality surge protector. Plugging your computer into a surge protector instead of directly into the wall outlet will protect your computer from surges of electricity which might cause an overload to the sensitive components, and damage the computer.
A virus is a small piece of software that piggy-backs on real programs, and causes the computer to perform certain unwanted functions. There are several types of viruses:
E-mail virus, which moves around in e-mail messages and usually replicates itself by automatically mailing itself to addresses in the victim's e-mail address book.
Worm, which is a small piece of software that uses computer networks and security holes to replicate itself
Trojan Horse, which is a normal computer program that claims to do one thing but in reality will do another thing, namely, cause damage when you run it.
The best way to protect yourself against a computer virus is with an anti-virus program. These anti-virus programs check the computer for viruses and repair damaged or deleted files that are infected with the virus. Most companies that market anti-virus programs provide copies of their programs that can be down-loaded for free and used for a short period of time. The best way to protect yourself from viruses is to buy the copy of the anti-virus program. Since viruses are constantly being created, you will need to provide continuing protection for your computer. Purchasing the anti-virus program will provide you with updates for your anti-virus program so you can deal with new viruses as they come out.
You have just purchased a new computer. What steps will you take to ensure that your computer will give you dependable service for a long time to come?
