Operating System

An operating system (commonly abbreviated to either OS or O/S) is an interface between hardware and

user. An OS is responsible for the management and coordination of activities and the sharing of the resources of the computer. The operating system acts as a host for computing applications run on the machine. As a host, one of the purposes of an operating system is to handle the details of the operation of the hardware. This relieves application programs from having to manage these details and makes it easier to write applications. Almost all computers (including handheld computers, desktop computers, supercomputers, video game consoles) as well as some robots, domestic appliances (dishwashers, washing machines), and portable media players use an operating system of some type. Some of the oldest models may however use an embedded operating system, that may be contained on a compact disk or other data storage device. http://upload.wikimedia.org/wikipedia/commons/thumb/e/e1/Operating_system_placement.svg/165px-Operating_system_placement.svg.png
