What are the software systems of a computer?

System software and application software

System software refers to the system that controls and coordinates computers and external devices, supports the development and operation of application software, and is a collection of various programs without user intervention, and its main function is to schedule, monitor and maintain computer systems; Responsible for managing the various independent pieces of hardware in a computer system so that they can work in harmony. System software enables computer users and other software to treat the computer as a whole, regardless of how each piece of underlying hardware works.

Application software refers to a type of software that is developed for a specific field and serves a specific purpose. Application software is directly oriented to the needs of users, they can directly help users improve the quality and efficiency of their work, and even help users solve certain problems. Application software generally falls into two categories:

One is the practical software developed for specific needs, such as accounting software, scenery booking system, project budget software and educational auxiliary software, etc.: the other is a tool software provided for the convenience of users to use the computer, such as word for word processing, AutoCAD for auxiliary design and Rising antivirus software for system maintenance.

Computer software systems can generally be divided into two categories: system software and application software.

System software is a variety of programs that are used to manage the resources of a computer and to facilitate the user's use of the computer.

Computer software systems include system software, support software, and application software.

The operating system is a kind of system software that manages software and hardware resources, controls the execution of programs, changes the human-computer interface, reasonably organizes the computer workflow and provides a good operating environment for users to use the computer.

The operating system is an indispensable, most basic and most important system software that is located above the hardware layer and below all the software layers. It uniformly controls, schedules, and manages all the software, hardware, and data resources of a computer system.

The most important and basic thing in computer software is the operating system. It is the lowest level of software, which controls the programs running on all computers and manages the resources of the entire computer, and is the bridge between the bare metal of the computer and the applications and users. Without it, users can't use a certain software or program.

1.Operating system.

It is the control and management center of the computer system, and from the perspective of resources, it has four functions: processing machine, memory management, device management, and file management.

2.Programming language design.

The general process of computer problem solving is that the user writes a program in computer language, inputs it into the computer, and then the computer translates it into machine language, and outputs the result after running it on the computer. The development of programming languages has gone through five generations – machine languages, assembly languages, high-level languages, non-procedural languages, and intelligent languages.

3.Language processors.

Computers can only directly recognize and execute machine languages, so in order to run high-level language programs on computers, they must be equipped with program language translation programs, which are a set of programs themselves, and different high-level languages have corresponding translation programs.

4.Database management program.

A database management system is a large piece of software that manipulates and manages databases and is used to establish, use, and maintain databases.

5.System-assisted processors.

The system auxiliary processing program is also known as "software development and development tools", "support software" and "software tools", which mainly include programs, debugging programs, equipment and connection programs, and debugging programs.
