What Is an Operating System?

  • by

Operating systems are the software that runs behind the scenes of an individual computer, and manages a host of hardware components such as memory as well as file systems and input/output devices like keyboards, monitors printers, modems, etc. It also regulates access to the central processor unit, or CPU.

An OS allows multiple programs to be running simultaneously, a process called multitasking. This is because the OS assigns system resources to programs, like memory space and CPU, during execution. It monitors the program’s use of these resources and ensures that the program doesn’t interfere with other programs using these same resources.

Operating systems track where files are located and their current location on the computer’s disk. They create virtual directories and store metadata, like the date of creation or modification. An OS also makes it easier for applications to connect to the hardware of a computer via drivers. These drivers translate the hardware’s proprietary language into a common language that operating systems can recognize.

When an application needs to save the file, it connects to the operating kernel of the system. This is because the program cannot directly connect to the drive, and requires drivers to communicate with it. The operating system then creates and translates the www.myopendatablog.com/what-if-your-nintendo-switch-stops-turning-on/ file request into a logical operation, and the hardware is used according to the instructions.
