A terminal, also known as a command-line interface (CLI) or console, is a text-based interface used to interact with a computer's operating system or software. It allows users to issue commands and receive textual feedback. This contrasts with graphical user interfaces (GUIs) which rely on visual elements like icons and windows.

Terminals are fundamental tools for many computing tasks, especially in server administration, software development, and advanced system management. Users can navigate file systems, execute programs, configure settings, and automate processes using specific commands. The specific commands and their syntax vary depending on the operating system and the shell environment in use, such as Bash, Zsh, or PowerShell.

While GUIs are often more intuitive for beginners, terminals offer greater power, flexibility, and efficiency for experienced users. Scripting, where a series of commands are saved and executed as a single unit, is a common practice in terminal environments for automating repetitive tasks. Many developers and system administrators prefer terminals for their speed and precise control over the system.

Modern operating systems typically include a built-in terminal application. For example, macOS and Linux distributions come with a terminal emulator, while Windows offers Command Prompt and PowerShell. These applications provide a window into the underlying command-line environment of the operating system.
