How Computers works?

This flyer is about Computer and history of Computers.


In the 21st century computer is important for us. Computers these day we need them to do works and others. Now, in this flyer it will give you information about the four generations.

Also it will talk about the farther of Computer Alan Turing and the hero of World Wide Web [www] Sir tim-Berners Lee. At first what is a Motherboard? A Motherboard is a the heart of the computer. What is a C.P.U? Well first it is stand for it stands for Central Processing Unit. It is where it do the instruction and everything like Mathematics E.T.C.


First Generation Computer

The first generation was during 1946-1959. The First Generation is used by vacuum tubes and that it is for the C.P.U and make a lot of heat. Punched cards, paper tape, and magnetic tape were used as input and output devices. They use machine code for programming.

Second Generation

The Period of the second Generation is from 1959-1965. It is use as a less power it is faster than the first generation. It is use by Magnetic core, Magnetic tape and Magnetic disks. The rest it's the same.

Third Generation

The period of the third generation is from 1965-1971. The third Generation uses integrated circuits. The third Generation is way smaller than the other two generations It uses less heat, faster and still cost a lot.

Fourth Generation

The period of the fourth Generations was 1971-1980.The fourth Generation was a lot powerful still it uses less heat than the other 3 generations. The style of it is smaller and portable and the internet was invented.

Well he is famous for 2 things 1: He crack the code for England during World War 2. 2: He was the person who created the first computer and these day we call him the father of computer.

Sir Tim Berners-Lee

Sir Tim Berners-Lee was born on June 8 1955. He was the man who invented World Wide Web (WWW) Sir Tim Berners-Lee was a scientist. We know he created the World Wide Web but when already created it he did not wanted to get paid and it was a lot of money he earned. H invented on 1989 and he was knighted by the Queen Elizabeth on 2004 and on 2007 he earned a merit from UK's order of Merits.
