An operating system is a software component that manages the resources and provides services to the software applications running on a computer. The three functions of an operating system are:
1. Resource management: An operating system manages the computer's hardware resources, such as CPU, memory, disk, and network devices, and allocates them to running processes as needed.
2. Process management: An operating system creates, schedules, and terminates processes, which are the running instances of software applications.
3. User interface: An operating system provides a user interface that allows users to interact with the computer and its applications, such as a command-line interface or a graphical user interface.
