What does CLI stand for in computing?

The term CLI stands for Command Line Interface. In computing, a command line interface is a text-based interface that allows users to interact with the operating system or software applications by typing commands into a console or terminal. Unlike graphical user interfaces (GUIs), which rely on visual elements like windows and icons, CLIs require users to remember and input specific command syntax to perform tasks.

Using a CLI can be more efficient for advanced users who are familiar with the commands, as it often allows for faster execution of system functions and can be scripted for automation. This makes CLIs particularly powerful for system administration, programming, and development tasks.

Understanding the concept of a command line interface is essential for IT professionals, as it is widely used in various operating systems, including Unix, Linux, and Windows, particularly in server management and software development environments.
