Operating Systems

An operating system (OS) is a set of programs containing instructions that coordinate all the activities among hardware and software components of a computer system. It is like a shop keeper who keeps a shop in order by attending to customers, handling supplier deliveries, stocking the shelves, doing the bookkeeping, and so on.

The operating system relies on device drivers to communicate with each device in the computer. The operating system also contains instructions to run application software.
