The main functions of the operating system are resource management, program control and human-computer interaction. The resources of a computer system can be divided into two categories: equipment resources and information resources. Device resources refer to the hardware devices that make up the computer, such as the central processing unit, main memory, disk storage, printers, tape storage, monitors, keyboard input devices, and mice. Information resources refer to various data stored in the computer, such as files, program libraries, knowledge bases, system software and application software, etc.
