How operating systems work?

An operating system is the application that controls every aspect of a computer. The most common operating systems are Windows, UNIX and Macintosh. To put it simply, an operating system carries out two basic functions it serves as a manger for the hardware and software resources held in the system and it deals with hardware without the applications having to know every aspect along the way. The duties of the operating system fall into six different categories processor management, memory management, device management, storage management, application interface and user interface.

First, your computer's operating system coordinates the demands that the computer's software makes on its hardware, especially the central processing unit. Each piece of software running on your computer ideally would like to have the undivided attention of its hardware. It's the operating system's job to make sure that each application gets its fair share of your computer's finite resources in the most efficient way possible.

Second, the operating system provides a consistent set of rules for applications to use in order to be able to interface with your computer's hardware. The system's application program interface lets developers create software that will run on computers of the same type even if the hardware is different or open to change.
