GUI Introduction

Graphical user interfaces (graphical user Interface, or GUI, also known as graphical user interface) refer to the graphical display of the computer operation user interface.

The graphical interface is visually more receptive to the user than the command-line interface used by earlier computers. The interface, however, is bound to have more computing power than simple message rendering by prompting the user to "change of state" in a specific location on the display, with "a variety of beautiful and non-monotonous visual messages".
