The operating system is a system software that controls and manages all computer resources. It is a computer program that manages computer hardware and software resources. The operating system needs to handle things such as managing and configuring memory and determining the supply and demand of system resources. Basic things like prioritizing, controlling input and output devices, operating networks, and managing file systems.

The operating system is a system software that controls and manages the computer?
All computer resources.
The operating system is a system software that controls and manages the computer (all computer resources).
The operating system (operating 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.
In a computer, 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.
Extended information
In the early days of the birth of the computer operating system, its architecture was a simple architecture. Due to the various influencing factors at that time, such as hardware performance, platform, software level, etc. The restrictions made the computer operating system structure at that time appear in a chaotic and ambiguous state. The operating system's user applications and its kernel programs were mixed, and even the addresses and spaces they ran in were consistent.
This kind of operating system is actually a simple combination of a series of processes and projects, and the module method used is relatively rough, which makes its structure macroscopically very vague.
With the continuous development of computer network and application technology, information system security issues have attracted more and more people's attention. Once the information system is damaged, users and units will suffer heavy losses. Effective maintenance of the information system Protection is an urgent issue that must be faced and solved, and operating system security is crucial to the overall security of computer systems. Strengthening operating system security reinforcement and optimization services is a key link in achieving information system security.
Currently, the main threats to operating system security include system vulnerabilities, fragile login authentication methods, ineffective access control, computer viruses, Trojan horses, covert channels, system backdoor malicious programs and code infections, etc. Strengthen operations System security reinforcement work is the basis for the security of the entire information system.
