1. What may be the possible problems if computer today are still not based on a graphical user interface (GUI)? 2. Why do you think Windows still the leading operating system despite it being a commercial software?
. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs),[3][4][5] which require commands to be typed on a computer keyboard.
The interim Dynabook GUI (Smalltalk-76 running on the Xerox Alto)
The actions in a GUI are usually performed through direct manipulation of the graphical elements.[6][7][8] Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term GUI tends not to be applied to other lower-display resolution types of interfaces, such as video games (where head-up display (HUD)[9] is preferred), or not including flat screens, like volumetric displays[10] because the term is restricted to the scope of two-dimensional display screens able to describe generic information, in the tradition of the computer science research at the Xerox Palo Alto Research Center.
