What are 20 differences between GUI and CUI?

GUI (Graphical User Interface) and CUI (Character User Interface) differ in numerous ways that impact usability, resource consumption, and interaction style. GUIs feature visual elements like windows, icons, buttons, and menus, making them intuitive and user-friendly for many, particularly those unfamiliar with technical commands. They offer immediate visual feedback and support for multitasking through multiple windows and tabs. GUIs also tend to consume more system resources due to their graphical components. They are generally easier for beginners to learn and include built-in help systems and visual cues. Customization in GUIs is often achieved through themes and settings, and error handling is presented in a user-friendly manner through dialogs and pop-up messages.

In contrast, CUIs rely on text-based commands and interactions through a command line or terminal. This interface requires users to remember specific commands and syntax, which can be challenging for novices but offers more precise control for experienced users. CUIs are highly resource-efficient, making them suitable for environments with limited graphical capabilities. They support extensive automation through scripting, and error handling is provided as text output. Multitasking in CUIs involves managing multiple terminal sessions, and customization is done through text-based configuration files. Error recovery typically requires manual intervention, and CUIs are commonly used in server environments or remote access situations where graphical interfaces are impractical.
