A modern computer system consists of one or more processors, some main memory, disks, printers, a keyboard, a display, network interfaces, and other input/output devices. All in all, a complex system. Writing programs that keep track of all these components and use them correctly, let alone optimally, is an extremely difficult job. For this reason, computers are prepared with a layer of software called the operating system, whose job is to manage all these devices and provide user programs with a simpler interface to the hardware. We can tell it in simple word, the operating system controls the entire hardware and the application software. It provides the software platforms.
