Computer software systems can be divided into two categories: 1. System software refers to a system that controls and coordinates computers and external devices, supports the development and operation of application software, and is a collection of various programs that do not require user intervention. , the main function is to schedule, monitor and maintain computer systems; 2. Application software is a collection of various programming languages that users can use and applications compiled in various programming languages. It can broaden the application fields of computer systems, Amplify the capabilities of your hardware.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The computer software system refers to the various programs, data and related documentation that the computer runs. Computer software systems are usually divided into two categories: system software and application software. Computer system software can ensure that the computer runs normally according to the user's wishes. In order to meet the various needs of the user for using the computer, it helps the user manage the computer and maintain resources, execute user commands, control system scheduling and other tasks.
Computer software systems can be divided into two categories: system software and application software. Although their uses are different, what they have in common is that they are all stored in computer memory in a certain way. A program or data written in a format encoding.
1. System software
Although various application software complete different tasks, they all require some common basic operations, such as input The device obtains data, sends data to the output device, stores and writes data to the outside, reads data from the external memory, performs regular management of data, and so on. These basic tasks are also completed by a series of instructions. People organize these instructions together to form specialized software to support the operation of application software. This software is called system software.
System software refers to a 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 computer systems; it is responsible for Manage various independent hardware in a 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. ), is that part of the software that supports the normal operation of the computer system and enables user operations.
System software is usually included with the computer system when it is purchased, and can also be installed separately as needed.
The main features of the system software are:
It has strong interactivity with the hardware
It can share resources Scheduling management
can solve the coordination problems existing in concurrent operation processing
The data structure is complex and the external interfaces are diverse, making it easy for users to repeat Use
2. Application software
Application software (Application) corresponds to the system software and is a variety of programs that users can use Design languages, as well as collections of application programs compiled in various programming languages, are divided into application software packages and user programs. An application software package is a collection of programs designed to use computers to solve certain types of problems, mostly for users to use.
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.
