It controls the memory, operations, software, and hardware of the computer. You can converse with the computer using this method even if you don't understand its language. A computer cannot function without an operating system.

An operating system performs three primary tasks: managing the computer's resources, including the CPU, memory, disc drives, and printers; creating a user interface; and running and supporting application software.
