GUI and CUI are two types of User Interfaces. GUI stands for Graphical
User Interface
while CUI stands for Character User Interface. In this article we will be discussing the differences between these two interfaces and which one has advantages over the other.

User Interface : User Interface comprises of everything the user can use to interact with the computer. It is basically the means by which the user and computer system can interact using input and output devices.

GUI: GUI stands for Graphical User Interface. This is a type of user interface
where user interacts with the computer using graphics. Graphics include icons, navigation bars, images etc. Mouse can be used while using this interface to interact with the graphics. It is a very user-friendly interface and requires no expertise. Eg: Windows has GUI.

CUI: CUI stands for Character User Interface. This is a type of user interface
where user interacts with computer using only keyboard. To perform any action a command is required. CUI is precursor of GUI and was used in most primitive computers. Most modern computers use GUI and not CUI. Eg: MS-DOS has CUI.
