GUI stands for **Graphical User Interface**. It differs from a Command-Line Interface (CLI) in the following ways:
1. **Interaction Method**:
- **GUI**: Uses graphical elements such as windows, icons, buttons, and menus to allow users to interact with the software. Users can perform tasks by clicking, dragging, and dropping these elements.
- **CLI**: Requires users to input text commands via a command prompt. Users must type specific commands and parameters to perform tasks.
2. **Ease of Use**:
- **GUI**: Generally more user-friendly and intuitive, especially for those who are less experienced with computers. It provides visual feedback and more direct interaction.
- **CLI**: Can be more complex and requires knowledge of the specific commands and syntax. It offers more control and precision but may have a steeper learning curve.
3. **Efficiency**:
- **GUI**: Can be less efficient for repetitive tasks or complex operations due to the need for mouse clicks and navigation.
- **CLI**: Often more efficient for power users and automation, as commands can be scripted and executed quickly without navigating through graphical elements.
Overall, GUIs are preferred for everyday tasks and general users, while CLIs are favored by advanced users and for tasks requiring precise control or automation.
