A '''terminal emulator''', or '''terminal application''', is a [[Application software|computer program]] that [[Emulator|emulates]] a video [[Computer terminal#Dumb terminals|terminal]] within some other display architecture. Though typically synonymous with a [[Command-line interface|shell]] or [[text terminal]], the term ''terminal'' covers all remote terminals, including graphical interfaces. A terminal emulator inside a [[graphical user interface]] is often called a '''terminal window'''.

A terminal window allows the user access to a text terminal and all its applications such as [[command-line interface]]s (CLI) and [[text user interface]] (TUI) applications. These may be running either on the same machine or on a different one via [[telnet]], [[Secure Shell|ssh]], [[dial-up]], or over a direct [[serial port|serial connection]]. On [[Unix-like]] operating systems, it is common to have one or more terminal windows connected to the local machine.

Terminals usually support a set of [[escape sequences]] for controlling color, [[Cursor (computers)|cursor]] position, etc. Examples include the family of terminal control sequence standards that includes [[ECMA-48]], [[ANSI X3.64]], and [[ISO/IEC 6429]].
