What is an operating system in a computer software system?

The operating system is the system software in the computer software system. It is a computer program that manages computer hardware and software resources. The operating system needs to process, such as managing and configuring memory, determining the priority of system resource supply and demand, and controlling input devices. and output devices, operating networks, and managing file systems.

The operating system is the system software in the computer software system and a computer program that manages computer hardware and software resources. The operating system needs to handle basic tasks such as managing and configuring memory, determining the priority of system resource supply and demand, controlling input and output devices, operating the network, and managing the file system. The operating system also provides an operating interface for users to interact with the system.

System software includes operating system, language processing system, system performance testing, utility software, etc.

Various application software, although they complete different tasks, they all require some common basic operations, such as input devices Obtain data, send data to output devices, store and write data to external storage, read data from external storage, general management of data, etc. 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. 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 connections, etc.), which supports computer systems. That part of the software that runs normally and implements user operations.

System software is usually included with the computer system when it is purchased, and can also be installed separately as needed.

Introduction to operating system:

In computers, the operating system is the most basic and important basic system. software. From the perspective of a computer user, the computer operating system embodies the various services it provides; from the perspective of a programmer, it mainly refers to the interface or interface for user login; from the perspective of a designer, it refers to Connections between various modules and units. In fact, the key to the design and improvement of a new operating system is the design of the system structure. After decades of development, computer operating systems have developed from a simple control loop at the beginning into a more complex distributed operating system. Coupled with the increasingly diverse needs of computer users, computer operating systems have become one of the complex and huge computer software systems.

Introduction to language processing system:

Programming language processing system varies with the language being processed and its processing methods and processes. However, any language processing system usually contains a translation program, which translates a program in one language into an equivalent program in another language. The translated language and program are called source language and source program respectively, and the language and program generated by translation are called target language and target program respectively.

Introduction to database management:

Database management systems store large amounts of data in an organized and dynamic manner, allowing people to use these data conveniently and efficiently.

Database management system is a large-scale 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.

Introduction to auxiliary programs:

System auxiliary processing programs are also called "software development tools", "support software" and "software tools". They mainly include editing programs, debugging programs, equipment and Linker, debugger.
