the.com/graphical user interface

means A way of operating a computer through visual elements like windows, icons, and menus instead of typed commands.

from From Greek 'graphikos' (having to do with drawing or writing) plus the much newer 'interface,' a term borrowed from physics and engineering meaning the boundary where two systems meet. The whole phrase was assembled in computing labs in the latter half of the 20th century, as researchers moved screens away from blinking cursors and command lines toward windows, icons, and pointers you could actually see and click — most famously prototyped at Xerox PARC before Apple and Microsoft made it the default way humans argue with machines.
