Answer:
An operating system (OS) is a type of software that manages the hardware and software resources of a computer. It is the foundation on which other programs, such as application software, are built.
There are three main components of an operating system:
- The kernel: This is the central part of the operating system that manages the hardware and software resources of the computer. It is responsible for allocating memory, controlling the input/output devices, and managing the system's resources.
- The shell: This is the interface between the user and the kernel. The shell allows the user to interact with the operating system using commands and programs.
- System libraries: These are collections of reusable software routines that provide common services to application programs. They are often used for tasks such as input/output, math operations, and other common tasks.
Together, these components form the core of an operating system, and they work together to provide the basic functionality that allows a computer to run.
