What does the operating system do to the computer software and hardware?

The role of the operating system is to manage computer software and hardware resources. An operating system is a computer program that manages computer hardware and software resources; it needs to handle basic matters such as managing and configuring memory, determining the priority of system resource supply and demand, controlling input and output devices, operating networks, and managing file systems.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The role of the operating system is to manage computer software and hardware resources.

The computing operating system can be said to be very important to the computer. 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 computer operating systems can reduce the work intensity of manual resource allocation, reduce the user's intervention in computing operations, 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:

①Process management, its work is mainly process scheduling. In the case of a single user and a 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.

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

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

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