What is the full form of Computer?
The computer is an electronic device that is used for processing data by using hardware and software. The full form of Computer is commonly operated machine particularly used for technical and educational research.
What is Computer and its Parts?
In simple words, we can say that the computer is an electronic device along with its components i.e. hardware and software (just like apps in mobile) which makes our life easier by processing raw data output in any form given to it, into a meaningful data as desired by the user. There is a lot of software and hardware are available in the market as per the user requirements.

What are the Generations of Computers?
The Generations of computers is defined on the basis of major technological changes:-
- First Generation (1940-1956) – uses vacuum tubes, ENIAC was the first computer of this generation.
- Second Generation (1956-1963) – uses transistors rather than vacuum tubes.
- Third Generation (1964-1971)- ICs (integrated circuits) used in place of transistors which reduced the size of computers.
- Fourth Generation (1972-2010) – uses microprocessors and ICs.
- Fifth Generation (2010- present) – the fifth generation of computers uses AI (artificial intelligence) and some best examples of these are Siri on iPhone, Cortana on Windows 8 and 10.
