Computing Hardware

And Computing History

Computing Hardware

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.

Hardware is a generic term for any part of the computer that you can phsically touch, pick up, hold, move around the room. In other works harsdware are the phsical parts that make the computer

External Hardware

Monito, so you can see what you are working on

Printer - so you can get a paper copy of your work

Keyboard - so you can type text, numbers and symbols into your work

Mouse - so you can poiint, clilck and select things on your screen

Microphone - so you can input voice or sound recordings

Internal Hardware

Hard Disk - To store all of your applications and files

CPU (Central Processing Unit)- the "brains" of the computer

Fan - to keep the CPU Cool and stop it overheating

MotherBoard - the main printed circuit board int eh computer with sockets to connect to the other parts

Sound card - used to generate and cpature sounds

How To Identify The Components Inside Your Computer

History of Computing

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.
