Points where two systems, subjects, or organizations meet and interact. In computing, the means by which users interact with computer programs or hardware.
From 'inter-' (between) + 'face,' literally meaning 'between faces.' Coined in the 1880s for physical boundaries, it gained prominence in computing in the 1960s as human-computer interaction became crucial.

Every smartphone screen is an interface between human intuition and digital logic, making the complex simple through design.
