Graphical User Interface


What Are The Benefits Of A Gui?

There is also a command window for entering commands and a configurable button panel for frequently used commands. The source display window is used to display breakpoints, the current line where execution has stopped, and other relevant information found in most software debuggers.

The first known Graphical User Interface was developed at Xerox’s Palo Alto Research Center. In about 1979 this group, under the direction of Alan Kay, developed the first object-oriented programming language , a windowing operating system that had networked several computers together. An operating system is the software component of a computer system that is responsible for the management and coordination of activities and the sharing of the resources of the computer. The OS acts as a host for application programs that are run on the machine. As a host, one of the purposes of an OS is to handle the details of the operation of the hardware. This relieves application programs from having to manage these details and makes it easier to write applications. The GUI consists of a source display window where source and assembly-level code is displayed.

The GUI familiar to most of us today in either the Mac or the Windows operating systems and their applications originated at the Xerox Palo Alto Research Laboratory in the late 1970s. Later, Microsoft used many of the same ideas in their first version of the Windows operating system for IBM-compatible PCs. Right from its first release, Windows 95 will include an off-screen model which software developers will be able to use as the basis of non-visual representations of the screen. To some extent the success of the adaptation has depended on the level of access to the existing visual software. Microsoft’s Windows is the most used GUI and it is with the new release of this software, Windows 95, that possibly the greatest innovation will occur.

What are the three types of interface?

There are five main types of user interface:command line (cli)
graphical user interface (GUI)
menu driven (mdi)
form based (fbi)
natural language (nli)

The order that tasks are performed by the program is under the user’s control – not the program’s control! This means a GUI program must keep track of the “state” of its processing and respond correctly to user commands that are given in any order the user chooses. This style of programming is called “event driven programming.” In fact, by definition, all GUI programs are event-driven programs. The GUI interface visually acknowledges and confirms each type of activities performed by the users. For example when the user deletes a file in the Windows operating system, then the operating system asks for the confirmation before deleting it.

Additional windows are used to display variables, waveforms, etc. that are displayed to a user and then it simply waits for the user to interact with them.
