Computer Science

Jon Porter

What would happen to the world if we took all the computers out of it tomorrow？ What would happen if the Internet， which is called the World Wide Web for a very good reason， stopped working？

Do you have a computer？ When did you last use it？ Can you remember the last time you went a day without using a computer？

I cant.

B Computer science， which teaches you about computers and how they work， is a ‘young science. The first ever course was in Cambridge， England， in the 1950s， but now it is a very popular science around the world. As computers become more and more important in our lives， computer science will become more and more important every year.

C The first modern， digital or electronic computers of the 20th century were as big as some houses or their bedrooms， but now … well， you dont need me to tell you how small computers are these days. You probably have one in your pocket or handbag or even in your hand right now， and its probably talking to you while you read the words on this paper （very old-fashioned！）， bringing you information and messages from around the world.
