What Is A Computer?

A computer is an electronic device that processes data and performs tasks according to a set of instructions called programs. It consists of both hardware (the physical components) and software (the programs and operating systems that run on it). The main functions of a computer include input (receiving data), processing (manipulating data), storage (saving data), and output (producing results). Computers can range from small personal devices like laptops and smartphones to large systems like servers and supercomputers used for complex computations and data management.
