This article will explain in detail which is the most basic and core software in the computer system software. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The most basic and core software in computer system software is "operating system". The operating system is the most basic system software that runs directly on the computer hardware, and it is the core of the system software. Only the hardware equipment of the computer with the operating system can be called, otherwise the computer can not be used.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The most basic and core software in computer system software is "operating system".

Operating system (operation system, referred to as OS) is a computer program that manages computer hardware and software resources. The operating system needs to deal with basic tasks such as managing and configuring memory, determining the priority of supply and demand of system resources, controlling input and output devices, operating networks and managing file systems. The operating system also provides an interface that allows users to interact with the system.

In the computer, the operating system is the most basic and most important basic system software. From the computer user's point of view, the computer operating system embodies the services it provides; from the programmer's point of view, it mainly refers to the user login interface or interface; from the designer's point of view, it refers to the relationship between various modules and units.

In fact, the key work of the design and improvement of the new operating system is the design of the architecture. After decades of development, the computer operating system has developed from a simple control cycle to a more complex distributed operating system. Coupled with the increasingly diversified needs of computer users, the computer operating system has become one of the complex and huge computer software systems.

The operating system mainly includes the following functions:

① process management, its work is mainly process scheduling, in the case of a single user and a single task, the processor is only occupied by one task of one user, and the work of process management is very simple. However, in the case of multi-program or multi-user, when organizing multiple jobs or tasks, it is necessary to solve the problems of processor scheduling, allocation and recycling.

② storage management is divided into several functions: storage allocation, storage sharing, storage protection, storage expansion.

③ equipment management has the following functions: equipment allocation, device transmission control, device independence.

④ file management: file storage space management, directory management, file operation management, file protection.

⑤ job management is responsible for handling any requests submitted by the user.
