Overview of GUI System
A GUI system allows the user to perform highly complex tasks without having to know the steps
required to accomplish the task. Through a menu or button, the user can access files, make
formatting changes, perform operations, and make changes. A GUI system also allows more than
one file or window to be open at the same time.
Mouse
In addition to the keyboard, a GUI system utilizes a device referred to as a mouse. A mouse is
generally smaller than the hand (unless you have very small hands). For most people, it fits in the
palm of the hand when the hand is palm-side down on the table or work surface.
The underside of the mouse has a ball that rolls whenever the mouse is moved on the table
surface and moves the cursor on the screen. The top side of the mouse has several parts. Toward
the heel of the hand is the casing over the ball component. In front of this, where the fingers rest,
are moveable sections referred to as buttons. The number of buttons on a mouse can vary.
Generally there are two or three. They are referred to as left, center, or right buttons. If the
mouse has only two buttons, the functions requiring the center button are performed by using
both buttons simultaneously.
The mouse performs tasks when the cursor is placed on the desired position on the screen and a
single or double click is used on the appropriate button.
Cursor
The cursor appears on the screen to identify the current location within a window or file. This
could be within the body of the window or file, the menu, or other defining areas. The cursor
could have several different forms, depending on where it is and the specifics of the system the
user is working in. The shape of the cursor at a given location identifies the function it can
perform there. In the MCC terminal GUI, the cursor can take the form of an X, an arrow, a t-bar,
an I, or a|.
