What are the two categories of computer software and what are the categories of computer software

Computer software refers to programs and their documentation in a computer system. A program is a description of the processing object and processing rules of a computing task; The documentation is intended to facilitate the clarification of the information required for the procedure. Programs must be loaded inside the machine to work, and documentation is generally for people to see, not necessarily into the machine.

Software is the interface between the user and the hardware. Users communicate with their computers primarily through software. Software is an important basis for the design of computer systems.

For the convenience of users, in order to make the computer system have a high overall utility, when designing the computer system, it is necessary to consider the combination of software and hardware, as well as the requirements of the user and the requirements of the software.

The correct meaning of software should be:

1) Runtime, a collection of instructions or computer programs capable of providing the required functionality and performance.

2) The program is able to satisfactorily process the data structure of the information.

3) Documentation that describes the functional requirements of the program and how the program operates and uses the requirements.

Software has different characteristics than hardware:

1) Different forms of expression.

The hardware is tangible, colored, smelly, visible, touchable, and smelly. And software is invisible, colorless, odorless, invisible, intangible, and invisible. Most of the software exists in people's heads or on paper, and whether it is correct or not, whether it is good or bad, will not be known until the program is running on the machine.

This creates many difficulties in design, production and management.

2) Different production methods.

Software is development, which is the high exertion of human intelligence, not hardware manufacturing in the traditional sense. Although there are many commonalities between software development and hardware manufacturing, the two activities are fundamentally different.

3) The requirements are different.

Hardware products allow for errors, while software products do not.

4) Maintenance is different.

Hardware is to be used for the old, in theory, the software will not be used for the old, but in practice, the software will also become old and bad. Because throughout the lifetime of the software, it is in a state of change (maintenance).

Therefore, software is divided into system software and application software.

System software such as operating system.

Application software such as: Word WPS RAR, etc.

Computer software is basically divided into:"System software"with"Application software"There are two broad categories, but this is just a more general statement.

Computer software is divided into two categories: system software and application software, the system software is the operating system platform for the normal operation of the computer (such as: windows95, windows98, windows2000 xp, etc.), and the application software is an auxiliary computer tool (such as: office, photoshop, ie, etc.)

Software is divided into two categories: system software and application software, and system software refers to DOS Windows95 98 2000 XP

Application software: QQ, office software, Kingsoft typing 、......

System software and application software.

There are two categories, system software and application software.

System software and application software, also known as tool software.

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

Software is various operating systems like Windows, Linux, Unix, etc. Including the patches of the operating system and the hardware driver, it is all system 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 is a collection of various programming languages that can be used by users and applications compiled in various programming languages, which are divided into application software packages and user programs. For example, a blind application package is a collection of programs designed to solve a certain type of problem using a computer, and is mostly used by users.

Application software is the part of the software provided to meet the application needs of users in different fields and different problems. It can broaden the application field of computer systems and amplify the capabilities of hardware.

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

System software is a variety of operating systems, such as Windows, Linux, Unix, etc., as well as operating system patches and hardware drivers, all of which are system software.
