Operating Systems Quiz

An operating system is system software that manages computer hardware and software resources, and provides common services for computer programs.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other resources.
