Computer software can generally be divided into "system software" and "application software". System software refers to the system that controls and coordinates computers and external devices, and supports the development and operation of application software. It is responsible for managing various independent hardware in the computer system so that they can work in harmony. Application software is that part of software provided to meet the application needs of users in different fields and problems; it can broaden the application fields of computer systems and amplify the functions of hardware.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
Computer software (Software, also called software) is computer programs, procedures, rules, and possible files, documents and data related to the operation of computer systems. Software is the interface between the user and the hardware. Users communicate with computers primarily through software. Software is an important basis for computer system design. In order to facilitate users and make the computer system have high overall utility, when designing the computer system, the combination of software and hardware, as well as user requirements and software requirements must be considered comprehensively.
# According to the functions and characteristics of the software, computer software can generally be divided into system software and application software.
System software
System software refers to the system that controls and coordinates computers and external devices, and supports the development and operation of application software. It is a collection of various programs that do not require user intervention. Its main function is to schedule, monitor and maintain the computer system;
System software is responsible for managing various independent hardware in the computer system so that they can work in coordination. 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, interpreters;
operating systems;
database management systems.
Application software
Application software is provided to meet the application needs of users in different fields and problems. Some software. It can broaden the application fields of computer systems and amplify the functions of hardware.
Application software is a collection of various programming languages that users can use, as well as application programs compiled in various programming languages. It is divided into application software packages and user programs.
Application software package is a collection of programs designed to use computers to solve certain types of problems for use by multiple users.
Application software 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
