What should a complete computer software system include

The computer software system refers to the various programs, data and related documentation that the computer is running.

Computer system software can ensure that the computer runs normally according to the user's wishes. In order to meet the various needs of the user for using the computer, it helps the user manage the computer and maintain resources, execute user commands, control system scheduling and other tasks. Software systems are divided into two major categories. Although their uses are different, what they have in common is that they are programs or data written in a certain format and encoded in a computer memory.

System software

System software refers to a type of computer software that is responsible for controlling and coordinating the computer and its peripheral devices, and supporting the development and operation of application software. System software generally includes operating systems, language processing programs, database systems and network management systems.

System software refers to various types of operating systems, such as windows, Linux, UNIX, etc. It also includes operating system patches and hardware drivers, which are all system software categories.

Application software

Application software refers to a type of software developed for a specific field and serving 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 is generally divided into two categories: one is practical software developed for specific needs, such as accounting software, setting systems, engineering budget software and educational assistance software, etc.; the other is provided to facilitate users to use computers. A tool software, such as Word for word processing, AutoCAD for auxiliary design, and Rising anti-virus software for system maintenance.

There are even more types of application software that can be subdivided, such as tool software, game software, management software, etc., all belong to the application software category.

A computer software program is a description of the processing objects and processing rules of a computing task; documentation is the explanatory information needed to facilitate understanding of the program.

3. Shareware: Trial versions can usually be obtained and used for free, but are limited in functionality or usage period. Developers will encourage users to pay to obtain a fully functional commercial version. Free software: It can be obtained and reprinted for free, but the source code is not provided and cannot be modified.
