This article mainly introduces the computer operating system refers to what computer programs, the text is very detailed, has a certain reference value, interested friends must read!

Operating systems are computer programs that manage computer hardware and software resources. Operating systems handle basic tasks such as managing and configuring memory, prioritizing system resource supply and demand, controlling input and output devices, operating networks, and managing file systems.

An operating system (OS) is a computer program that manages computer hardware and software resources. Operating systems handle basic tasks such as managing and configuring memory, prioritizing supply and demand for system resources, controlling input and output devices, operating networks, and managing file systems. The operating system also provides an interface for users to interact with the system.

Computer operating systems are divided into different types according to different uses. From the functional point of view, there are real-time systems, batch processing systems, time-sharing systems, network operating systems, etc.

Real-time system mainly means that the system can respond to external commands quickly, deal with problems in the corresponding time, and coordinate the system work.

The time-sharing system can realize the user's human-computer interaction needs, and multiple users use a host together, which greatly saves resource costs. Time-sharing system has the advantages of multi-path, independence, interaction and timeliness, and can realize user-system-terminal tasks.

Batch processing systems emerged in the 1960s to improve resource utilization and system throughput.

A network operating system is a software program that can replace an operating system. It is the heart and soul of a network. It is a special operating system that provides services to network computers. Through the network to achieve mutual transmission of data and various messages, divided into servers and clients. The main function of the server is to manage the sharing of various resources and network equipment on the server and the network, to integrate and control traffic, to avoid the possibility of paralysis, and the client is able to receive the data transmitted by the server to use the function, so that the client can clearly search for the required resources.
