  5 Types of Interfaces •Command Line Interface (CLI) A CLI displays a prompt, the user types a command on the keyboard, the computer executes the command and provides textual output. • Menu Driven Interface The user has a list of items to choose from, and can make selections by highlighting one.  Graphical User Interface (GUI) Uses windows, icons, menus and pointers (WIMP) which can be manipulated by a mouse (and often to an extent by a keyboard as well).  Natural Language Interface Can range from simple command systems to voice activated text processing. Commands are spoken in “normal” language. 18/03/2013
