Mouse
A mouse
is an elector-mechanical, hand-held device
It is used
as a pointer. It can perform functions
like
selecting menu commands, moving icons, resizing windows,
starting
programs, and choosing options.
The most
common mouse uses an internal, magnetically coated
ball, to
detect the movement of the mouse across a flat surface,
usually a
desktop. Now a days Optical or laser mouse is used to
detect the
movement. All windows based applications today are
designed
to work with a mouse. A mouse is used to replace hard
-to-remember
key combinations with easier "Point and Click"
actions.
However, it cannot substitute all keyboard operations.
It can be
alternative for commands based operations.
