Definition of User Interface
In computer science and human-computer interaction, the user interface of a computer program refers to the graphical, textual and auditory information the program presents to the user.
›››››››››››››››››››››››››››››››
The user employs several control sequences such as keystrokes with the computer keyboard, movements of the computer mouse, or selections with the touchscreen to control the program.

Graphical User Interface (GUI): The use of pictures rather than just words to represent the input and output of a program. Input is accepted via devices such as keyboard and mouse.
