Hardware- Computer Componets
and the history of computers
Introduction
I am going to discuss Drives, Monitors, Touch Screens, Motherboards and much more about hardware. I will also be talking about the history of computing and will be including Alan Turing and Tim Berners-Lee. I will also be talking about the 4 generations of computing.
Computer Drive
A computer drive can store and read information. An example of a drive is a disc. A disc is an input device because it stores information and then you put that information into the computer.
Touch-Screen
You can get many touch-screen devices such as a touch-screen laptop, tablet, smart phone and iPods. It is when you have the ability to use them with your hand and you do not need a mouse or buttons on your phone.
Monitor
The monitor is the screen of the computer. It is where you see everything you do. You can send the display from the computer to the TV.
Input devices
Input devices are when you put information/storage into a computer for example a disc.
Output device
An output device is the opposite to an input device so you take storage/information out of the computer. For example a printer because you are printing information out of the device.
Motherboard
A motherboard allows computer components to communicate.
Hardware
The hardware is what you use or what you are on. Such as the screen or the system unit. Everything you use whilst using a computer is hardware.
CPU
The Cpu is the brains of the computer. It stands for the Central Processing Unit and handles all the instructions from the hardware.
RAM/ROM
Stores information that can be accessed anywhere- computer storage location.

This video is all about the hardware of a computer.
Born in London in 1912, Alan Turing was a British computer scientist, mathematician and did so much more. He played a vital part in code-breaking in WW2. Alan Turing was awarded an Order of the British Empire for his work.
Tim Berners-Lee is an English computer scientist, best known as the inventor of the World Wide Web. In 2004, Berners-Lee was awarded by Queen Elizabeth for his work.
First Genration
First Generation (1940-1956) Vacuum Tubes. It was developed by 2 scientists called Mauchy and Tchert. The first generation of computers were very slow and also very large.
Second Generation
Second Generation (1956-1963) Transistors. The scientists at bell laboratories developed the 2nd generation of computers. The computers became smaller, faster and cheaper.
Third Generation
Third Generation (1964-1971) Integrated Circuits. Jack Kilby discovered the 3rd generation in 1958. The computer became smaller and faster again.
4th generation
This is the 4th generation of computing, the generation we have now. The computers became smaller and much faster again. There is now a lot of choice when chooses a computer or laptop or Phone.
