Computer is the adorable invention to help the human kind!

What is computer?

A computer is like a super-fast, super-smart electronic brain that can do all sorts of tasks, like sending messages, playing games, or storing information. It's like having a really clever friend who can help you with almost anything, but it only understands instructions given in its own language, called code.

Computer is an electronic device which accept data from the user and process it to provide a meaningful result as information to the user.

Working stages:

  • Inputting : Users gives some data to the computer trough some basic input device like Keyboard, Mouse, Touch pad etc.
  • Processing : Computer has it's own mechanism structure to handle different inputs of the user like mathematical, arithmetical etc.
  • Outputting : Users provide the inputs with desire to get information and proper result or solution of the problem, And computer gives the solution in form of output device such as Monitor, speaker etc.
