How to Purchase, Install, and Maintain a Computer

 

At some point in your life, you will probably decide to purchase a computer. Aside from understanding the components discussed earlier, it also is important to be able to find the computer that best fits your needs. For example, most new computers come with application software already installed. If you do not use this software, then it is of no value even though you got it for "free." There are several things to look for when purchasing a new computer. If possible, speak to someone who is familiar with the purchasing process and can guide you along.

For most people, buying a computer is an expensive experience. Despite this, many people are woefully uninformed when they set out to purchase a computer. Although desktop computer systems remain popular, since 1993 sales of laptop, notebook, and smaller computers have rivalled sales of larger systems, partly because of their enhanced capabilities and increased use by field sales forces. Be careful when setting up a computer system. Failure to follow health guidelines can lead to painful, and even permanent, disabilities. Government studies indicate repetitive stress disorder (RSI) and cumulative trauma disorder (CTD), the most commonly reported problems associated with prolonged keyboard use, are responsible for half of work-related illnesses. Computer security is an increasingly important issue. A survey of American companies with more than 200 personal computers showed that over 60% had suffered at least one virus attack. Two of the major sources of viruses, free software and illegally copied software, more commonly are used by small companies and private individuals, so the percentage of PC users affected by viruses may be much higher. E-mail attachments have been the carriers of several recent virus attacks that have infected both business and home computer users.
