Today computers come in all shapes and sizes.There were still big computers for companies or universities. There are other special computers for factories. These large computers tell the fatory machines what to do. But there are also small personal computers to use at home or in an office. There are even computers in telephones, television sets , and cars. These computers have to be small. They are so small that you cannot even see all their parts.
Computers are very useful, but they also can cause problems. One kind of problems is with the computer's memory. It is not perfect so sometimes computers lose important information. Another problem is with the machinery. Computers are machines, and machines can break down. When the computers break down, they may erase information, like chalk on a blackboard. Or they may stop doing anything at all. And there is another different kind of problem with computers. Some doctors say they may be bad for your health. They say you should not work with computers all day.
