Answer:
- Resource management
- User interface
- File management
Step-by-step explanation:
Resource management
One of the main functions of an operating system is to manage the computer's resources, including the CPU, memory, disk space, and input/output devices. The OS ensures that each application gets the resources it needs to run smoothly without interfering with other applications.
User interface
The operating system provides a user interface that allows users to interact with the computer and its applications. This can be in the form of a graphical user interface (GUI) with icons and windows or a command-line interface (CLI) that uses text commands.
File management
The operating system manages files and directories on the computer's storage devices. This includes creating, moving, copying, deleting, and renaming files and directories. The OS also manages file permissions and access control to ensure that only authorized users can access certain files or directories.
