Operating systems (OS) are a set of integrated programs that manage computer resources and operations. From a user’s point perception, the OS isn’t visible, however, it offers applications with services to make computer software and hardware more usable.

Access to data stored on disks is an essential operating system function, and requires the OS to have a way of organizing the contents of each file to improve speed, reliability and storage efficiency. This type of structure, referred to as the file-system, permits files to have attributes and names. They can also be organized into directories or folders to form the directory tree.

The majority of computers are fitted with a variety of hardware devices, like keyboards, printers, mice and other peripherals. These devices depend on driver software for the device to communicate with the operating system. The operating system installs and configures these drivers in order to provide the appropriate service to applications. It also hides hardware details from the user so that they can communicate with their computer without knowing the precise configuration of the hardware.
