What are the five basic functions of the operating system?

1, process management, its work is mainly process scheduling. In the case of single user and single task, the processor is monopolized by only one user's task, 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 problem of processor scheduling, allocation and recycling.

2. Storage management is divided into several functions: storage allocation, storage enjoyment, storage protection and storage expansion.

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

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

5. Job management is responsible for handling any requirements submitted by users.

Extended data:

Computer operating system is very important to computers. From the user's point of view, the operating system can schedule all the resources of the computer system, including hardware and software equipment, data information and so on. The use of computer operating system can reduce the intensity of manual allocation of resources, reduce the user's intervention in calculation, and greatly improve the intelligent work efficiency of computers.

Secondly, in terms of resource management, if multiple users jointly manage a computer system, the information sharing between the two users may conflict.

In order to allocate the various resource blocks of the computer more reasonably and coordinate the various components of the computer system, it is necessary to give full play to the functions of the computer operating system, optimize and adjust the efficiency and usage of each resource block, so that the needs of all users can be met.
