One function of an operating system is managing hardware resources. The operating system is responsible for coordinating and controlling various hardware components of a computer, such as the CPU, memory, disk drives, and peripherals. It ensures that different programs and processes run smoothly without conflicts over resource allocation.
Another function is providing an interface for users to interact with the computer. This includes graphical user interfaces (GUIs) like Windows, icons, menus, and pointers, as well as command-line interfaces (CLIs) that allow users to input commands to perform tasks.
Additionally, managing files and directories is another crucial function of an operating system. It organizes and controls access to files and directories on storage devices, allowing users to store, retrieve, and manipulate data efficiently.
In this case, the correct answer would be: All answer choices are correct, as each of the functions listed (providing an interface, managing files and directories, and managing hardware resources) are indeed functions of an operating system.
