2. Providing a user interface: The OS provides a graphical user interface (GUI) or a command-line interface (CLI) for the user to interact with the system.
3. Managing software applications: The OS manages the installation, execution, and termination of software applications, and provides a runtime environment for them.
4. Providing security: The OS provides security features such as user authentication, access control, and data encryption to protect the system and user data.
5. Managing file systems: The OS manages the storage and retrieval of files and directories on the disk or other storage devices.
6. Managing processes: The OS manages the creation, execution, and termination of processes and threads, and provides process synchronization and communication mechanisms.
7. Providing networking capabilities: The OS provides networking capabilities to allow communication between computers and devices on a network.
Overall, the OS provides a platform for the user to run applications and perform tasks efficiently and securely.
