What is the most important thing in system software

The most important system software is the operating system. The operating system is a computer program that manages computer hardware and software resources. It is the lowest software in the computer system. The operating system controls all computer running programs and manages the resources of the entire computer. It is the bridge between the bare metal of the computer, applications and users. Without it, users cannot use a certain software or program.

What is system software

System software refers to a system that controls and coordinates computers and external devices, supports the development and operation of application software, and is a variety of systems that do not require user intervention. A collection of programs whose main function is to schedule, monitor and maintain a computer system; it is responsible for managing various independent hardware in the computer system so that they can work in harmony. System software allows computer users and other software to treat the computer as a whole without having to consider how the underlying hardware works.

What is an operating system?

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

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.

Expand knowledge:

In a computer, the operating system is the most basic and important basic system software.

• From the perspective of a computer user, the computer operating system embodies the various services it provides;

• From the perspective of a programmer Say, it mainly refers to the interface or interface for user login;

• From the perspective of a designer, it refers to the connection between various modules and units.

In fact, the key task in the design and improvement of a new operating system is the design of the architecture. After decades of development, the computer operating system has evolved from a simple control system at the beginning. The loop has developed into a more complex distributed operating system. Coupled with the increasingly diverse needs of computer users, the computer operating system has become one of the complex and huge computer software systems.
