A computer is a machine that can perform calculations using a set of instructions. Computers have input devices like keyboards and mice to enter information, and output devices like monitors, printers, and projectors to present information.

Common software includes word processors, spreadsheets, web browsers, and email programs, while specialized software exists for tasks like finance, drafting, and tutorials.
