COMPUTERSTony plans to write an article about computers.This is some of the information he has collected.Hidden helpers.Not so many years ago.You hardly ever saw computers.Now they are everywhere.There may also be tiny hidden computers in your home that you are unaware of.There may be one inside your TV set, telephone or washing machine.So maybe you depend on computers more than you realize.What kind of jobs can a computer do?It is common knowledge that computers are super calculators.They can calculate very fast and rarely give wrong answers.They can also type, print and draw things like diagrams and graphs.They can teach you and play games with you.More importantly, they can operate railways (like the Underground) and fly aero planes and spaceships.For these reasons, we often call them electronic brains.Is a computer cleverer than I am?The answer to this question is, for the time being, 'No'.Your brain can understand the meaning of things better and create new ideas.However, one day computers may be able to do most things that a human brain can do and do them better.They may be better than doctors, judges and teachers at doing their jobs.If this is true, it raises interesting questions.What will happen to us if computers can do our jobs?How will we spend our lives? Will we have nothing to do?Computers may change our lives.But will they make them better?How do we give a computer instructions?We give a computer instructions by putting a program into it.The program is written by a human being, and it is essential that the human does make a mistake.If we want a computer to do different jobs, we have to give it different programs.CD-ROMsMany of today's computers have CD-ROM drives. A CD-ROM can hold over 300,000 pages of writing, and can also contain pictures and sound. Thus, for example, you can use your computer to read about a famous person in history such as John F Kennedy and you can see a photograph or video of him, and even listen to him speaking. Some people think that CD-ROMs will soon be more popular than books.
