There are four main categories of system software:

1. Operating system.

Features: The most important and basic computer software is the operating system (OS). It is the lowest level of software, which controls the programs running on all computers and manages the resources of the entire computer, and is the bridge between the bare metal of the computer and the applications and users.

Without it, users can't use a certain software or program.

The operating system is the control and management center of the computer system, and from the perspective of resources, it has 4 functions: processor, memory management, device management, and file management.

Commonly used systems include DoS operating system, Windows operating system, Unix operating system, Linux, Netware and other operating systems.

2. Language processing programs.

Features: The computer can only directly recognize and execute machine language, so to run a high-level language program on the computer, it must be equipped with a program language translation program, the translation program itself is a set of programs, and different high-level languages have corresponding translation programs.

Language processing programs such as assembly language assembler, C language compiler, connector, etc.

3. Database management.

Features: The database management system stores a large amount of data in an organized and dynamic manner, so that people can use the data conveniently and efficiently.

A database management system is a large piece of software that manipulates and manages databases and is used to establish, use, and maintain databases.

FoxPro, Access, Oracle, Sybase, DB2, and Informix are database systems.

4. Auxiliary programs.

Features: The system auxiliary processing program is also called "software development tool", "support software" and "software tool", which mainly includes programs, debugging programs, equipment and connection programs, and debugging programs.

Key features of the operating system:

1. Concurrency.

Concurrence refers to the simultaneous execution of two or more running programs at the same time interval.

2. Sharing.

Sharing means that the resources in the operating system, including hardware resources and information resources, can be used by multiple concurrently executing processes.

3.Asynchronicity.

In a multi-process environment, multiple processes are allowed to execute concurrently, and due to limited resources, there are many processes, and in most cases, the execution of the process is not consistent, but "stop-and-go".

Classification of operating systems.

1. Single-user operating system.

2. Batch operating system.

3. Real-time operating system.

4. Time-sharing operating system.

5. Network operating system.

6. Distributed operating system.

7. Microcomputer operating system.

Summary. What are the two main categories of software? 1.

System software refers to a type of computer software that is responsible for controlling and coordinating computers and their 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. 2.

Application software refers to a type of software that is developed for a specific field and serves 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 to use.

Computer system software refers to the system that controls and coordinates computers and external equipment, 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. Includes:

1. Assembly language assembler.

Assembly language is a low-level language based on the processor instruction system, which uses mnemonics to express instruction opcodes and identifiers to represent instruction operands.

2. C language compiler.

Since C implements the programming of hardware, C combines the functions of a high-level language and a low-level language. It can be used for the development of both system software and application software.

3. Connectors.

Connectors are a type of component that our electronic engineers and technicians often come into contact with. Its function is very simple: to build a bridge of communication between the blocked or isolated circuits in the circuit, so that the current can flow, so that the circuit can achieve the intended function.

4. DOS operating system.

DOS is an MS-DOS developed by Microsoft Corporation in 1979 for IBM personal computers, and it is a single-user, single-task operating system. Later, the concept of DOS also included MS-DOS-compatible systems produced by other companies.

5. Windows operating system.

Microsoft Windows operating system is a set of operating systems developed by Microsoft Corporation in the United States, Windows adopts a graphical mode GUI, which is more user-friendly than the previous way that DOS needs to type instructions.

Computer application software refers to a variety of programming languages that can be used by users, as well as a collection of applications written in various programming languages, which are divided into application software packages and user programs. Includes:

1. Texter.

It is used as an application for writing ordinary text, and it differs from a document processor (or word processor) in that it is not used as a desktop publishing (e.g. document formatting), but as a source for writing programs.

2. Accounting software.

The computer software software system and its functional modules specially used for accounting and financial management include a set of programs for directing computers to carry out accounting and management work, store data and related information.

What are the characteristics of the software.

Features of the software:

1. Intangible, there is no physical form, and the function, characteristics, and quality can only be understood through the operating status.

2. Software penetrates a lot of mental work, and people's logical thinking, intelligent activities and technical level are the key to software products.

3. The software will not age and wear out like the hardware, but there are defects in maintenance and technical updates.

4. The development and operation of software must depend on a specific computer system environment, and there is a dependence on hardware.

5. The software is reusable, and the software is easily copied after development, thus forming multiple copies.

Definition of software.

Software, pinyin is ruǎnjiàn, and the definition of software in the national standard is: computer programs, procedures, rules, and possible documents, documents, and data related to the operation of a computer system.

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

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

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

Using the development language as the description language, it can be considered as follows: software = program + data + documentation.

There are three main types of software:

demos: Presentation software.

A version of commercially released software that allows users to understand the functions of the software first, mainly introducing the functions that can be achieved by the software and the features of the software. If you like this software, you can go and buy the official version.

shareware: shareware.

A type of software that you can try before purchasing or registering. This type of software is copyrighted, but you can use it for free**. However, after a certain period of trial time, you must register or purchase the software to continue using it.

It should be noted that most shareware is not permanently free, and the developer's goal is still to hope that users will eventually purchase their products, so shareware is often limited in terms of use, or only provides partial functionality, but compared to pure free software, shareware is much stronger in terms of security.

freeware: Free software.

Answer] :(1) Software is a logical entity, not a concrete physical entity, and has a strong abstraction. We can only record it on media or run it on the system, but we can't see the software directly through our eyes.

2) Software is a logically complex and large-scale system, involving many aspects of technology, management and so on. If you think of ** as a part, a piece of software is a complex of millions of parts, and its structure is much more complex than a mechanical device. It should be said that the complexity of the software is higher than that of hardware products of the same size.

3) Software is an intellectual product, and its value is reflected in the knowledge and ability to solve problems, but not in the software carrier itself. The production method of software is obviously different from that of hardware, and the design method and manufacturing of the middle roll section are different; The cost of software generation is mainly in R&D design, while mass replication has almost no cost.

4) During the operation and use of the software, there is no wear and tear of the hardware. However, software maintenance is much more complex than hardware maintenance, and software failures are mainly caused by changes in the software and changes in the use environment.

5) The development and operation of software has a strong dependence on hardware. In software development, there is the problem of portability, and software portability is now usually regarded as one of the important factors to measure the quality of software.

6) There are many social factors involved in software work. Software is closely related to people, involving many aspects such as language, culture, and even ethics.
