terminal emulation



  • noun the ability of a terminal to emulate the functions of another type of terminal so that display codes can be correctly decoded and displayed and keystrokes correctly coded and transmitted


  • The ability to make one computer terminal appear as another type of terminal to another. Terminal emulation is used, for instance, to enable a user with a graphical-user interface to log-on to and enter commands into a text-based system such as an older mainframe. In this manner, such a terminal appears to the accessed mainframe as another mainframe.
