Graphical Unit Interface (Gui)

A graphical user interface (GUI) is a type of user interface that allows users to interact with electronic devices in a graphical way, usually using a pointing device such as a mouse, stylus, or trackball. GUIs were introduced in the early 1980s as a way to make personal computers (PCs) easier to use for non-technical users.

They have since evolved into much more sophisticated interfaces, and are now widely used on almost all electronic devices with a display screen, including smartphones, tablets, gaming consoles, and many types of industrial equipment. The term “graphical user interface” is used to describe two different but related concepts:

• A style of user interface in which graphical elements are used to represent information and actions that can be taken by the user; and

• The software code that implements this style of user interface.

When people talk about “a GUI,” they are usually referring to the second definition: the software that allows users to interact with a device in a graphical way. But it’s important to understand both definitions, because they are closely related. The design of a GUI is heavily influenced by the capabilities of the software that implements it. And conversely, the functionality of the software is often limited by the design of the GUI.
