This article mainly introduces what functions the operating system has, which is very detailed and has a certain reference value. Friends who are interested must finish it!

Operating system is a kind of system software. The operating system is a computer program that manages computer hardware and software resources. it needs to deal with basic tasks such as managing and configuring memory, determining the priority of supply and demand of system resources, controlling input and output devices, operating networks and managing file systems.

Operating system is a kind of system software.

Operating system (Operating System, referred to as OS) is a computer program that manages computer hardware and software resources. The operating system needs to deal with basic tasks such as managing and configuring memory, determining the priority of supply and demand of system resources, controlling input and output devices, operating networks and managing file systems. The operating system also provides an interface that allows users to interact with the system.

The operating system of computing can be said to be very important to the computer. from the point of view of users, the operating system can schedule various resource plates of the computer system, including software and hardware equipment, data information, etc., the use of computer operating system can reduce the intensity of human resource allocation, and reduce the degree of user intervention in computing operations. The intelligent work efficiency of the computer can be greatly improved.

Secondly, in terms of resource management, if multiple users work together to manage a computer system, then there may be conflicts in the information sharing between the two users. In order to allocate each resource plate of the computer more reasonably and coordinate the various components of the computer system, it is necessary to give full play to the function of the computer operating system and make an optimal adjustment to the use efficiency and degree of each resource plate, so that the needs of each user can be met.

Finally, with the assistance of computer programs, the operating system can abstractly deal with the basic functions provided by computing system resources, show the functions of the operating system to users by visual means, and reduce the difficulty of computer use.

The operating system mainly includes the following functions:

① process management, its work is mainly process scheduling, in the case of a single user and a single task, the processor is only occupied by one task of one user, and the work of process management is very simple. However, in the case of multi-program or multi-user, when organizing multiple jobs or tasks, it is necessary to solve the problems of processor scheduling, allocation and recycling.

② storage management is divided into several functions: storage allocation, storage sharing, storage protection, storage expansion.

③ equipment management has the following functions: equipment allocation, device transmission control, device independence.

④ file management: file storage space management, directory management, file operation management, file protection.

⑤ job management is responsible for handling any requests submitted by the user.
