Operating systems –

The operating system is a piece of software consisting of different programs and data which runs on the computer and manages all the hardware resources, also providing a more efficient way of executing programs.

 All desktops have one version of an operating system or another. The operating system is the framework which allows you to access and communicate with the computer’s hardware in an interactive way. Without the operating system you wouldn’t be able to give the computer tasks and it would therefore do nothing, hence why all computers have one. To make the computer easier to use with user friendly interfaces.  Examples of these would be Windows Vista and Windows 7.
