What does the operating system belong to?

The operating system is a computer program that manages computer hardware and software resources. The operating system needs to handle tasks such as managing and configuring memory, determining the priority of system resource supply and demand, controlling input devices and output devices, operating networks, and managing file systems. and other basic matters. Computer operating systems are divided into different types according to different uses. From a functional perspective, they include real-time systems, batch systems, time-sharing systems, network operating systems, etc.

Operating system (operation system, referred to as OS) is 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.

Computer operating systems are divided into different types according to different uses. From a functional perspective, they include real-time systems, batch processing systems, time-sharing systems, network operating systems, etc.

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

The time-sharing system can realize the user's human-computer interaction needs. Multiple users share a host, which saves resource costs to a large extent. The time-sharing system has the advantages of multi-channel, independence, interactivity and timeliness, and can realize user-system-terminal tasks.

Batch processing systems appeared in the 1960s. Batch processing systems can improve resource utilization and system throughput.

The network operating system is a software program that can replace the operating system. It is the heart and soul of the network and a special operating system that provides services to network computers. Data and various messages are transferred to each other through the network, which is 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, integrate and control traffic, and avoid the possibility of paralysis. The client is able to receive and use the data transmitted by the server. function so that clients can clearly search for the required resources.
