Hardware-Computer Componets

The History Of Computing


Today I am going to talk about:

Drives, Monitors, CPU's, RAM/ROM, Motherboards, Inputs/Outputs and Touchscreens.

I am also going to look at the history of computing including: Alan Turing, Tim Berners Lee and 4 generations of computers.


The hardware of a computer is all the wiring and electronic components that make the computer work and be able to let us get information, download, view and type things.

Computer Drives

Computer drives are mostly found in laptops but can be found in computers too. The drive is the bit in the side of the laptop or the computers CPU, which by pressing a button pops out. When it pops out there will be a place to put DVDs to watch films, computer games and CDs to download music onto your computer.

Computer Monitors

The computer monitor is basically the screen which allows us to view things. The only difference between and computer monitor and TV screen (both in which look very similar) is that a monitor doesn't have a television tuner used to change channels. Monitors are also meant to have better display and clearness than TV screens.

Computer CPUs

CPU stands for central processing unit. You hardly find CPUs with laptops so it's mostly family, school work computers etc. The CPU is like the brains of the computer, where things are saved and stored and where most calculations and workings out take place.


RAM: Random Access Memory. This is a form of storage which allows data to be viewed and written. It's also where you save and load things from.

ROM: Read Only Memory. ROM allows data to be edited and deleted. ROM is often used to save things and enables the computer's system to work with other hardware like CPUs.


The motherboard is everything under the keyboard which are all these wires, buttons, metal bits and functions. This (also like the Hardware) makes the computer work. The motherboard also know as the mainboard, system board, planar board, logic board, mobo etc. Also holds the hardware and RAM/ROM
How To Identify The Components Inside Your Computer

Inputs and Outputs

Input: The act of entering data into a computer e.g. what you type into the computer, moving the mouse. Sort of telling the computer what to do.

Output: Any piece of computer hardware used to translate the results of data processing carried out by the computer which converts the electronically carried information into a readable form for us.

Touch Screens

Touch Screen: A specially generated form of computer e.g. smartphone, IPhone, IPad, IPod, Kindle etc. Which have a screen that is also an input device which then has sensors allowing you to control things by touch. Touch screens in order to work are very sensitive to pressure

What are the four Generations of computers?

First Generation 1951-1958

The first generation computer used vacuum tubes. The 1943 ENIAC had 18,000 vacuum tubes, consumed 150 kilowatt of power and weighed 30 tons. Not exactly the ideal computer.

Second Generation 1959-1964

The advent of transistor technology, allowed second generation computers to come into existence. Transistors were small, fast and more reliable for less power. Computers could perform a single operation in just microseconds and were capable to store data in kilos of bytes.

Third Generation 1965-1970

These computers used more versatile programming. They used multiprogramming and data base management. Payroll, building and other business tasks were performed by these computers.

Fourth Generation 1971-Present

The development of the microprocessor chip, which contains an entire central processing unit on a single silicon chip, led to construction of inexpensive computers. These computers used a large scale of integrated circuits and reduced the size and cost of computers. (5th generation is still being developed)

Alan Turing

Alan Turing was born in 1912. He was highly influential in the development of computer science. Turing is widely considered to be the father of theoretical computer science and artificial intelligence. During the second world war Turing worked for the government code and cypher school at Bletchley Park, Britain's code breaking centre.

Tim Berners-Lee

Tim Berners-Lee made the first communication between the client and sever through the internet in November 1989. He invented the World Wide Web. He is a fellow of the Royal Society, he was knighted in 2004 and was one of Time Magazines 100 most important people of the 20th century.
