Identify two functions of an operating system.

Management of Hardware and Software Resources: One of the primary functions of an operating system is to manage the hardware and software resources of the computer system. This includes the management of the CPU, memory, disk drives, printers, and other peripherals. The operating system ensures that each application gets the necessary resources it needs to perform its tasks, and also ensures that these resources are used efficiently.

User Interface: Another important function of an operating system is to provide a user interface. This can be a command-line interface, where the user types commands to interact with the system, or a graphical user interface, where the user interacts with the system through visual elements like windows, icons, and menus. The user interface makes it easier for users to interact with the computer system and use its functions.
