Contemporary pc operating systems and application software use a Graphical User Interface (GUI), which extensively uses icons, buttons, bars, and boxes to perform tasks.
What is a GUI?
A system of interactive visual components for computer software is known as a GUI (Graphical User Interface).
Compared to MS-DOS and the shell of Unix-like operating systems, a GUI is more user-friendly than a text-based command-line interface.
