A user needs to perform an administrative task that is most efficiently done by typing commands directly to the operating system. Which of the following interfaces should the user utilize?
Graphical user interface (GUI)
Device driver
Command-line interface (CLI)
Application Programming Interface (API)
The correct answer is the command-line interface (CLI). The CLI is a text-based interface used to interact with the operating system by typing commands, which is ideal for direct and efficient system administration. The Graphical User Interface (GUI) is a visual, icon-based interface that is generally more intuitive but can be less efficient for specific administrative tasks. An Application Programming Interface (API) is used by software to communicate with other software, not for direct user interaction with an OS. A device driver provides an interface for the OS to communicate with hardware, not for the end-user to type commands.
