How to Work with Computers

Explains every single part!

Hard Drive


Hard Drive: Is a data storage device used for storing digital information keeping them safe in a computer.

Optical Drive

Optical Drive: Is the part of the computer that includes CD’s and all sorts of discs for the laptop.

Monitor

Monitor: Originally computer monitors were used for data processing while television receivers were used for entertainment. Starting from the 1980’s and forward, computers (and their monitors) were used for data processing and entertainment.


CPU

CPU: It performs the general scientific, logical, and input/output operations of a computer system. It is known as the brains of the computer, and where most calculations take place.


RAM

RAM: Is a form of computer data storage. It stores all the data, so it’s basically like a hard drive, but slightly different.

Input and Output

Input/Output: Any information or data that is entered or sent to the computer to be processed is considered input. Anything that is sent from the computer to an internal or external device is output.


Motherboard

Motherboard: Connects all parts of the computer together

and it can be thought as the back bone of the computer, it holds everything together and gives them the power to do so.


Touch Screen:

Touch screens: Are the easier way of working on a computer, they’re quicker than other computers, and much easier to use than a mouse and a keyboard.

Operating Systems

Operating Systems: A minor level system that supports a computer’s basic functions.

Tim Berners Lee

Tim Berners Lee: Tim Berners Lee invented the World Wide Web in 1982 (www) so without the World Wide Web there would be no such thing as websites, and without websites, life would be really complicated.

Alan Turing

Alan Turing: Alan Mathieson Turing, OBE, FRS was a British mathematician, logician, cryptanalyst, philosopher, computer scientist, mathematical biologist, and marathon and ultra-distance runner.

The four generations of computers

The First Generation of Computers:


- Software using machine language.


- Mainly used for calculations as working out mathematical tables.


The Second Generation of Computers:


-Used mainly for scientific and Alan Turing: Alan Mathieson Turing, OBE, FRS was a British mathematician, logician, cryptanalyst, philosopher, computer scientist, mathematical biologist, and marathon and ultra-distance runner.


engineering apps.


-Frames were made out of transistors’.


The Third Generation of Computers:


-Used rarely for scientific and business applications.


-Mini computers appeared on the market.


The Fourth Generation of Computers:


-Qualified to multi program.


-Basic machines, and network computers.
