1. What is an operating system? What is the relationship between it and hardware and other software?

An operating system is a system software (or a set of programs) that controls and manages various hardware and software resources in a computer system and effectively organizes multiple programs to run. It is an interface between users and computers. Specifically:

• The operating system is software and system software.
• Its basic function is to control and manage various resources in the computer system and effectively organize the operation of multiple programs.
• It provides many services for users to use and expand hardware functions.

Relationship with hardware: the operating system directly controls and manages hardware resources, and many functions are implemented in combination with hardware operations (such as system interruption ). Operating systems require a good hardware environment.
Relationship with software: the operating system is the control management center of the entire computer system, and other software must be built on the operating system. The operating system has both the right to control and the necessary environment for its operation.
