Graphical User Interface (GUI)
A Graphical User Interface (GUI) is a design method letting the
user view and interact with information via different graphical
elements, such as windows, buttons, screens, wizards, etc.
Generally graphical interfaces require the use of a mouse to
navigate through the different elements.
Currently, Graphical User Interfaces are omnipresent and users
rarely encounter a situation where they cannot use one. Both the
Microsoft Windows operating system and Mac OS X present information
via graphical user interfaces.
An example of a non graphical user interface is the command-line
interface (CLI) which is found in Windows by using a command
prompt, where the user primarily interacts by typing commands with
the keyboard. Also, shells under Mac OS X or Linux operating
systems are considered non-GUI or CLI interfaces.
Cascade Server is inherently a Graphical User Interface due to the
fact that it is a web application. All things viewed through a web
browser are necessarily graphical.
