The operating system (OS) is a fully integrated set of specially designed programs that control the computer's overall operations and resources. The OS is invisible to the user, but it provides services that applications software can make hardware and software more efficient.
It is a fundamental operating system function. The OS must be capable of organizing the contents of files in order to improve speed, reliability and storage efficiency. This structure, called a file-system, allows files to be given attributes and names. They can also be arranged into directories or folders to form an a directory tree.
The majority of computers are fitted with a range of hardware devices, including keyboards, printers as well as other peripherals. These devices depend on device driver software to communicate with the operating system. The operating system installs and configures these drivers to provide the appropriate service to the applications. It also hides the hardware configuration from users so that they are able to interact with their system without knowing the precise configuration of the hardware.
Process Management
An OS keeps all the programs running on the computer and determines how much time should be allocated to each one in a multitasking scenario. It also manages interruptions applications create to keep a processor's focus and ensures that there is enough memory to allow an application to complete its task without interfering with other processes.
Operating systems also perform other tasks that are associated with the overall functioning of the computer such as maintaining the primary memory containing massive byte arrays, or word arrays which each have an address. The OS will track the amount of bytes used by various programs and then move, delete, or reorganize these bytes www.myopendatablog.com/how-to-add-music-to-snapchat/ to free up space.
