Detailed introduction:

The computing operating system can be said to be very important to the computer. From the use From the user's perspective, the operating system can schedule various resource blocks of the computer system, including software and hardware equipment, data information, etc. The use of the computer operating system can reduce the intensity of manual resource allocation and reduce the user's intervention in computing operations. The degree is reduced, and the computer's intelligent work efficiency can be greatly improved.

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

Finally, with the assistance of computer programs, the operating system can abstractly handle various basic functions provided by computing system resources, display operating system functions to users in a visual way, and reduce the difficulty of using the computer.

The operating system mainly includes the following functions:

1. Process management. Its main job is process scheduling. In the case of single user and single task, the processor is only for one user. Exclusively for one task, the work of process management is very simple. However, in the case of multi-programming 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, and storage expansion.

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

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

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