1. Process management: An OS manages the creation, scheduling, and termination of processes, which are the running instances of a program.
2. Memory management: An OS manages the allocation and deallocation of memory to processes and ensures that each process has the required memory resources.
3. File system management: An OS manages the creation, deletion, and modification of files and directories on disk storage.
4. Device management: An OS manages the interaction between hardware devices and software applications, providing device drivers and managing input/output operations.
5. Security: An OS provides security features such as access control, authentication, and encryption to protect the system and user data.
6. Network management: An OS provides network services such as TCP/IP protocol stack, routing, and network interface management.
7. User interface: An OS provides a user interface that allows users to interact with the system, including graphical user interfaces (GUIs), command-line interfaces (CLIs), and web interfaces.
8. Application support: An OS provides application programming interfaces (APIs) and libraries that enable software developers to create applications that can run on the OS.
