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.
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.
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.
What are the four Generations of computers?
First Generation 1951-1958
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.
