The word computer refers to an object that can accept some input and produce some output. In fact, the human brain itself is a sophisticated computer, and scientists are learning more about how it works with each passing year.

operating systems

An operating system is is software that manages computer hardware and software resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.

software

Computer software, or simply software is any set of machine-readable instructions that directs a computer's processor to perform specific operations.
