State SIX functions of an operating system.
1. Process management – The operating system is responsible for managing running processes, allocating system resources, and scheduling tasks to ensure efficient use of the computer's CPU.
2. Memory management – The operating system controls the allocation and deallocation of memory to processes and ensures that each process has enough memory to run smoothly without interfering with other processes.
3. File management – The operating system controls how files are stored, accessed, and organized on the computer's storage devices. It manages file permissions, hierarchy, and ensures data integrity.
4. Device management – The operating system communicates with and manages the computer's hardware devices, such as printers, keyboards, monitors, and storage devices, to ensure they function correctly and efficiently.
5. Security management – The operating system provides security features to protect data and resources from unauthorized access, such as user authentication, file permissions, and encryption.
6. User interface – The operating system provides a user interface that allows users to interact with the computer, such as through a graphical user interface (GUI) or a command-line interface, making it easier to navigate, access applications, and manage files.
