How is computer software classified? What is a computer software system mainly made of?

Computer software consists of programs and related documentation. A program is a symbolic representation of a sequence of instructions, and a document is a technical document established during software development. A program is the main body of software and is generally kept in storage media (such as floppy disks, hard disks, and optical discs) for use on a computer.

Documentation is especially important for the use and maintenance of software, and the documentation that comes with the release of a software product is mainly a user manual, which contains the function introduction of the software product, the requirements of the operating environment, the installation method, the operation instructions, and the description of error messages. The operating environment of a software requirement refers to the configuration of the hardware and other software that it should at least have, that is, in the computer system hierarchy, it is the configuration that the lower (inner) layers of the software should at least have (including the equipment and index requirements for the hardware, the version requirements for the software, etc.). Computer software can be divided into system software and application software according to its use.

System software is mainly divided into three categories: operating system software (the core of the software), various language processing programs, and various database management systems.

Programs written to solve various computer problems are called application software. It can be divided into application packages and user programs.

Computer software is divided into: application software and system software. The system software mainly has some built-in program software, such as boot programs, compression software, and so on.

The popular saying of computer software is as follows, an operating system, that is, your usual XP, etc.

The second is application software, such as watching movies and listening to **. Drawing, office, gaming, web pages, anti-virus, etc. All kinds of software that you can work and study for you on the computer are all application software, and this kind of software can be applied by the general knowledge.

What a professional software system consists of is not clear in one or two sentences, nor is it clear here. Hehe.

According to the purpose of the software, computer software is generally divided into two categories: system software and application software.

1. System software.

System software provides the most basic functions for computer use, which can be divided into operating system and system software, of which the operating system is the most basic software.

System software is 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.

It includes a set of basic tools (such as compilers, database management, memory formatting, file system management, user authentication, driver management, network connectivity, etc.).

2. Application software.

Application software is software that has been 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 are closely related to each other and can work together, such as Microsoft's office software.

It can also be a large software system consisting of many independent programs, such as a database management system.
