A Graphical User Interface (GUI) is a visual way for users to interact with computers and software. Instead of typing commands, users can click on icons, buttons, and menus to perform tasks. This makes it easier for people to use technology without needing to understand complex programming languages. GUIs are commonly found in operating systems like Windows and macOS, as well as applications such as Microsoft Office and Adobe Photoshop. They often include elements like windows, toolbars, and dialog boxes, allowing users to navigate and manage their tasks intuitively. This user-friendly design has made computers accessible to a broader audience.
