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.

Computer hardware is the collection of physical parts of a computer system. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. Computer hardware is what you can physically touch

First generation of Computers
The first generation computers were huge, slow, expensive, and often undependable. The vacumm tube.
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 thetransistor which functions like a vacuum tube in that it can be used to relay and switch electronic signals
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 ofsilicon. Robert Noyce of Fairchild Corporation and Jack Kilby of Texas Instrumentsindependently 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.
forth generation of computers
This generation can be characterized by both the jump to monolithic integratedcircuits(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.
