RAM (random access memory) is the memory of the computer; where all your files are stored and kept. You can buy many different sizes of RAM, some with more memory than others.
what is RAM?


The CPU (abbreviation for central processing unit) is the brain of the computer, where most of the calculations take place. The CPU is, in terms of computing power, the most important element of a computer system. It is located in a socket on the motherboard, under a big heatsink and fan.

The Motherboard

The motherboard is like the heart of the computer. Everything is connected to the motherboard in some way and the mother board allows each part to communicate and pass data between each other. The mother board is what brings everything together.

Alan Turing

Younger life

Alan Turing was born on 23 June 1912 in London. His father was in the Indian Civil Service and Turing's parents lived in India. Turing and his brother stayed with friends and relatives in England, where he studied mathematics at Cambridge University. It was here that he developed the proof which states that automatic computation cannot solve all mathematical problems; this concept is known as the Turing machine and is considered the basis for the modern theory of computation.

The WAr

In 1926 Turning traveled to America and studied at Princeton University to two years, returning to England in 1638. While back in his own country he secretly started working part time for the British code breaking department.

On the outbreak of war with Germany he took up full time work at its headquarters, Bletchley Park. Here he played a vital role in deciphering the messages encrypted by the German Enigma machine, which provided vital intelligence for the allies. He also lead a team in the creation of a machine known as the "bombe" that successfully deciphered German messages and shortened the war by about 2 years!
