Operating
System
Description |
An operating system (OS) is system
software that manages computer hardware and software resources and provides
common services for computer programs. 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, printing, and
other resources. For hardware functions such as input
and output and memory allocation, the operating system acts as an
intermediary between programs and the computer hardware,[1][2] although the
application code is usually executed directly by the hardware and frequently
makes system calls to an OS function or is interrupted by it. Operating
systems are found on many devices that contain a computer – from cellular
phones and video game consoles to web servers and supercomputers. (LIMIT 50
