I will be describing the following hardware terminolgy and giving examples of use.
Drives, monitors, CPU, RAM/ROM, Motherboards, Inputs/Outputs, Touch Screens. i will also provide a history of computing and will look ath Alan Turning, Tim Berners-Lee and the four generations of computers.
The key board
The computer keyboard is important because it is the most effective input tool for letters and characters. Computer keyboards are analogous to the keys on a typewriter. Even if the technology has the ability to create letters and symbols, the keys are necessary to tell it which ones to create.
The monitor is the piece of computer hardware that displays the video and graphics information generated by the computer through the video card.
Monitors are very similar to televisions but usually display information at a much higher resolution.
He was an English mathematician, wartime code-breaker and pioneer of computer science.

First generation of computers
The first generation computers were huge, slow, expensive, and often undependable. The vacumm tube.
The second generation of computers
The transistor computer did not last as long as the vacuum tube computer lasted, but it was no less important in the advancement of computer technology. In 1947 three scientists, John Bardeen, William Shockley, and Walter Brattain working at AT&T's Bell Labs invented what would replace the vacuum tube forever. This invention was the transistor which functions like a vacuum tube in that it can be used to relay and switch electronic signals.
The third generation of computers
Transistors were a tremendous breakthrough in advancing the computer. However no one could predict that thousands even now millions of transistors (circuits) could be compacted in such a small space. The integrated circuit, or as it is sometimes referred to as semiconductor chip, packs a huge number of transistors onto a single wafer of silicon. Robert Noyce of Fairchild Corporation and Jack Kilby of Texas Instruments independently discovered the amazing attributes of integrated circuits. Placing such large numbers of transistors on a single chip vastly increased the power of a single computer and lowered its cost considerably.
The forth generation of computers
This generation can be characterized by both the jump to monolithic integrated circuits(millions of transistors put onto one integrated circuit chip) and the invention of the microprocessor (a single chip that could do all the processing of a full-scale computer). By putting millions of transistors onto one single chip more calculation and faster speeds could be reached by computers. Because electricity travels about a foot in a billionth of a second, the smaller the distance the greater the speed of computers.
