About GUI

GUI (Graphical User Interface) is an interface by using this interface we can interacts with electronic devices such as computers, hand-held devices and other appliances. This interface have icons, menus and other visual indicator Gadgets representations to display information. GUI provide also user related controls, unlike text-based interfaces, where data and commands are in text. GUI representations are manipulated by a pointing device such as a mouse, trackball, stylus, or a finger on a touch screen.The need for GUI became apparent because the first human/computer text interface was through keyboard text creation by what is called a prompt like DOS prompt. Commands were typed on a keyboard at the DOS prompt to initiate responses from a computer. The use of these commands and the need for exact spelling created a cumbersome and inefficient interface.
