Introduction to the operating system:
The operating system is a program that manages the hardware and software resources of a computer, and it is also the kernel and cornerstone of the computer system. The operating system is responsible for such basic tasks as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating networks, and managing file systems.
The operating system manages all the hardware resources of the computer system, including software resources and data resources; controls the operation of programs; improves the human-machine interface; provides support for other applications, etc., so that all the resources of the computer system can maximize its performance and provide users with convenient, effective, and user-friendly service interfaces. The operating system is a huge management and control program, which roughly includes five aspects of management functions: process and processor management, job management, storage management, device management, and file management.
Currently, the common operating systems on microcomputers are DOS, OS/2, UNIX, XENIX, LINUX, Windows, Netware and so on.
