Correct Answer

Explanation

Correct Answer Explanation:

A computer is an electronic device that accepts data as input, processes it according to a set of instructions (program), stores the results, and produces meaningful output. It performs multiple functions including calculations, communication, storage, and multimedia processing.

Why the other options are incorrect:

  • Option A: A computer does much more than just storing data. Storage is only one of its four main functions (input, processing, storage, and output).
  • Option C: Modern computers do far more than calculations. They handle multimedia, communication, gaming, design, and many other tasks.
  • Option D: A typewriter is a purely mechanical device with no processing capability. Computers are electronic and can process, store, and output data intelligently.
