What are computer software

Computer software is divided into two categories: system software and application software, including: 1. System software, such as windows, Linux, UNIX, etc., as well as operating system patches and hardware drivers; 2. Application software, Such as tool software, game software, management software, etc.

Computer software (Software, also called software) refers to the software in the computer system A program and its documentation. A program is a description of the processing objects and processing rules of a computing task; documentation is an explanatory material needed to facilitate understanding of the program. The program must be loaded into the machine before it can work. Documents are generally for people to see, not necessarily loaded into the machine.

Computer software is generally divided into two categories: system software and application software:

System software is various operating systems, such as windows, Linux, UNIX, etc., and also includes Operating system patches and hardware drivers are all system software.

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.

System software

System software 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.

Generally speaking, system software includes the operating system and a series of basic tools (such as compilers, database management, memory formatting, file system management, user authentication, driver management, network connection, etc. ).

Specifically includes the following four categories:

Various service programs, such as diagnostic programs, troubleshooting programs, practice programs, etc.;

Language programs, such as assemblers, compilers Programs, interpreters;

operating systems;

database management systems.

Application software

Application software is software developed for a specific purpose. It can be a specific program, such as an image browser. It can also be a collection of programs that have closely related functions and can cooperate with each other, such as Microsoft Office software. It can also be a huge software system composed of many independent programs, such as a database management system.

The more common ones are:

Word processing software such as WPS, Word, etc.

Information management software

Auxiliary design software such as AutoCAD

Real-time control software such as Jiyu Electronic Classroom, etc.

Education and Entertainment Software

Software development is the process of building a software system or software part of the system according to user requirements. Software development is a system engineering that includes requirement capture, requirement analysis, design, implementation and testing.

Software is generally implemented using a certain programming language. Development can usually be carried out using software development tools.

Different software generally has corresponding software licenses. Software users must agree to the license of the software they are using before they can legally use the software. On the other hand, the licensing terms for a particular piece of software cannot conflict with the law.
