Non-graphical

Referring to something that does not utilize or primarily rely on visual representations such as charts, diagrams, images, or other graphical elements to convey information or interact with a user. It emphasizes text-based or auditory interfaces, symbolic representations, or abstract data presentations, prioritizing alternative methods of information transmission and user engagement. non-graphical applications are often used in situations with limited visual display capabilities or when specific advantages are presented by alternative means of data presentation.

Non-graphical meaning with examples

• In the early days of computing, many operating systems were primarily non-graphical, relying on command-line interfaces where users typed commands to interact with the system. This required memorization of commands. Their text-based nature meant lower hardware resource demands. The lack of graphical elements however, proved to be less intuitive than newer OS.
• A blind person often uses non-graphical software or tools. This may include screen readers that vocalize text on the display or provide braille output for input and feedback. They often utilize keyboard navigation to navigate programs and access functions as well.
• In environments with low bandwidth connections or where data transfer speed is prioritized, non-graphical protocols or formats may be preferred. This is because text-based formats generally consume fewer data resources and are able to be processed quicker.
• Expert systems developed in the 1980s frequently featured non-graphical interfaces. These systems relied on users' textual input. They then would apply complex rule-based inferences to arrive at conclusions. While efficient at logic, these systems lacked any interactive visual elements.
• When setting up a server remotely using a command-line interface, the interaction is predominantly non-graphical. This method utilizes text-based commands to configure settings, manage files and execute operations, which are often easier and quicker to set up over SSH or other remote-access protocols.
