The full form of computer is “Common Operating Machine Particularly Used for Technical, Educational, and Research”. However, it’s worth noting that the term “computer” has become a common noun used to refer to electronic devices that perform various computing tasks and is no longer used as an acronym in most contexts.
A computer is an electronic device that is capable of accepting input, processing that input using mathematical or logical algorithms, and providing output in the form of information or actions. Computers can perform a wide range of tasks, from simple calculations to complex simulations and data analysis, and are used in almost every aspect of modern life.
