Computer Basics – What is the Computer – Computer History


A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data.



You probably already know that you can use a computer to type documents, send email, play games, and browse the Web.

You can also use it to edit or create spreadsheets, presentations, and even videos.
The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage (Father of Computer)

He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.


Generally speaking, computers can be classified into 5 Generations. Each generation lasted for a certain period of time, and each gave us either a new and improved computer or an improvement to the existing computer.

1) First Generation (1936-1956) Vacuum Tubes
2) Second Generation (1956-1963) Transistors
3) Third Generation (1964-1971) Integrated Circuits
4) Fourth Generation (1971-Present) Microprocessors
5) Fifth Generation (Present and Beyond) Artificial Intelligence
