What is a computer operating system?

The computer operating system is an essential system software in the computer system. Generally speaking, system software includes an 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.).

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The computer operating system is an essential system software in the computer system.

The operating system (OS) is a program that manages computer hardware and software resources. It is also the core and cornerstone of the computer system. The operating system is responsible for basic tasks such as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating networks, and managing file systems. The operating system manages all hardware resources of the computer system, including software resources and data resources; controls program operation; improves the human-machine interface; provides support for other application software, etc.

In a computer, the operating system is the most basic and important basic system software.

From the perspective of computer users, the computer operating system embodies the various services provided by it; from the perspective of programmers, it mainly refers to the interface or interface for user login; if from the perspective of designers, From a perspective, it refers to the 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, the computer operating system has developed from a simple control loop at the beginning to a more complex one. Distributed operating systems, coupled with the increasingly diverse needs of computer users, computer operating systems have become one of the complex and huge computer software systems.
