20 Mar GUI
Graphical User Interface. Computers and humans, when they need to interact, need an interface. The easier for humans to learn and use the interface, the better the interface is presumed to be. The folks at Xerox Palo-Alto Research Center (PARC) designed the first graphical (windowed) interface that was later used by Apple in their Macintosh line and yet later by Microsoft in their Windows lines of products.
