GUI
A GUI, or Graphical User Interface, is a user-friendly system that allows interaction with a computer through visual elements like icons, menus, and windows, instead of text-based commands. It uses a mouse or touchscreen to point, click, and drag, making it easier for users to navigate and operate devices.
Key characteristics
Visual interaction: Instead of typing commands, users interact with visual objects on the screen, such as icons, buttons, and sliders.
Point-and-click: A pointing device, like a mouse or a touch screen, is used to select and manipulate these visual elements.
Intuitive navigation: GUIs make complex operations more intuitive and accessible to a wider audience, as users don't need to memorize strict text commands.
Direct manipulation: Users can directly manipulate objects to perform actions, such as dragging a file to a trash can icon.
