How to Work with Computers
Explains every single part!
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: 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.
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.
and it can be thought as the back bone of the computer, it holds everything together and gives them the power to do so.

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.
-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.
