Terminal emulator

A terminal emulator, terminal application, term, or tty for short, is a program that emulates a "dumb" video terminal within some other display architecture.
A terminal emulator inside a graphical user interface is often called a terminal window. A terminal window allows the user access to a command-line interface (or occasionally a character-based application) which may be running either on the same machine or on a different one via telnet, ssh, or dial-up. On Unix-like operating systems it is common to have one or more terminal windows connected to the local machine, but on more graphically-oriented machines the remote use is more common.
Example programs providing the remote-access form of terminal emulation under Microsoft Windows include the built-in programs HyperTerminal and Microsoft's telnet client, as well as 3rd party programs like PuTTY, SSH, and SecureCRT. A so-called "DOS box" or "Command prompt" is the Windows equivalent of a locally-connected terminal window (in fact, it is a Win32 console). MS-DOS examples include ProComm, Qmodem, Telemate and Telix.
The ubiquitous UNIX terminal window is used for both local and remote access; where the connection goes is not the business of the terminal emulator itself. Many different terminal emulators are available for the X Window System - the most mature of the bunch are xterm, dtterm, and rxvt. Others include Eterm, aterm, multi-gnome-terminal, and konsole.
