Operating system

An operating system is the program that controls all the other parts of a computer system - both the hardware and the software. Most importantly, it allows you to make use of the facilities provided by the system. Every computer has an operating system.

The UNIX operating system has three important features; a kernel, the shell and a filesystem.
