An operating system is a fundamental software component that performs a variety of functions in a computer system.Explain at least five of those responsibilities?

1. Process Management: The operating system is responsible for managing processes, which are programs that are currently running on the computer. It allocates resources such as CPU time, memory, and input/output devices to different processes, and ensures that they run efficiently and without interfering with each other.

2. Memory Management: The operating system manages the computer's memory, allocating memory to different processes as needed and ensuring that each process has access to the memory it requires. It also handles memory protection, preventing processes from accessing memory that does not belong to them.

3. File System Management: The operating system is responsible for managing the computer's file system, which organizes and stores data on the computer's storage devices. It provides functions for creating, deleting, and accessing files, as well as for organizing files into directories and managing file permissions.

4. Device Management: The operating system manages the computer's input/output devices, such as keyboards, mice, printers, and network interfaces. It provides functions for controlling and communicating with these devices, and ensures that multiple processes can access and use the devices simultaneously without conflicts.

5. User Interface: The operating system provides a user interface that allows users to interact with the computer and its applications. This can take the form of a graphical user interface (GUI) with windows, icons, and menus, or a command-line interface where users type commands to perform tasks. The user interface also provides functions for managing files, running programs, and configuring system settings.
