It refers to a type of user interface that uses graphical elements like icons, menus, and windows to represent and interact with computer applications.
Here's what that means in simpler terms:
* Graphical: It uses visuals like pictures and symbols instead of just text commands.
* User Interface: It's how you communicate with the computer, like how you tell it what to do and how it shows you information.
Examples of GUIs:
* The desktop on your computer
* Your smartphone's home screen
* The icons you click on to open programs
* The menus you use to select options
Advantages of GUIs:
* Easier to use: Visual elements are often more intuitive to understand than text commands.
* More visually appealing: Graphical interfaces can be more engaging and pleasant to use.
* More accessible: GUIs can be easier for people with disabilities to use.
Before GUIs:
Before GUIs, computers were mostly controlled using text commands. This was much more difficult and time-consuming for most people.
