THE HISTORY OF THE COMPUTER<br />
The first computer was designed by Babbage, an English mathematician in 1822. It was enormous and it<br />
weighed three tons! For each calculation, you had to turn a handle hundreds of times! As a result, it was<br />
very slow. However, it was more precise than a modern calculator.<br />
A new system of keeping and transmitting information appeared in 1857: information was stored on long<br />
pieces of paper with holes in them. Then, Hollerith computers could "read" these pieces of paper. This<br />
system was very successful and lasted until the 1960s.<br />
The invention of transistors and microchips in the 1950s and 60s changed computer design: they became<br />
much smaller and cheaper. The first "modern" computer, with a screen and keyboard, appeared in 1975.<br />
We know computers have changed the world. In a short time, everybody will "wear" a small computer to<br />
talk to friends, to listen to music, to watch TV , to ... who knows?<br />
