Operating Systems

Operating Systems
An operating system is a layer of software which takes care of technical aspects of a computer's operation. It shields the user of the machine from the low-level details of the machine's operation and provides frequently needed facilities. There is no universal definition of what an operating system consists of. You can think of it as being the software which is already installed on a machine, before you add anything of your own.
Normally the operating system has a number of key elements: a technical layer of software for driving the hardware of the computer, like disk drives, the keyboard and the screen; a filesystem which provides a way of organizing files logically, and a simple command language which enables users to run their own programs and to manipulate their files in a simple way. Some operating systems also provide text editors, compilers, debuggers and a variety of other tools. Since the operating system (OS) is in charge of a computer, all requests to use its resources and devices need to go through the OS.
