Passage 1
Computers are very versatile. They can do many things such as teaching, playing games, or helping with a business, so choosing a computer is not an easy, simple job. But if you follow these steps, you will find it easier.
First, decide on the main reasons why you want a computer. Is this computer very useful for you? Is the most important reason to play games or to help with your business or to help with your schoolwork?
Second, look carefully at the programs the computer can use. Some people also write their own programs. If you want to write your own, it is important to look at the computer language. Is it easy to learn?
Third, decide the smallest, or the least needs you have for your computer. What are the characteristics you would like to have? For example, do you want a typewriter keyboard? Is a color display important to you? Your use of the computer will help you decide which characteristics are necessary, which are nice, and which are unnecessary.
Fourth, when you have limited your choices to a few computers, look at the secondary uses and programs. For example, if your main reason for buying a home computer is to play games, you may take computer A instead of computer B because computer A can also be used as a word processor.
Fifth, think of the price. There are prices to think about. The first price is the price you must pay to take the computer home. The second is the price of additional programs and possible additions that you might want to buy at a later date.
Be sure to try out the computer before you buy it. Sales people at computer shops are happy to help you choose the computer that will best fit your needs and cost you least.
