The computer
Mouse was invented in 1963 by a Mr
Douglas Englebart.His hardware invention is an input
device which allows us to control a cursor which in
turn,allows us to input data in the computer.
The Mouse
controls the pointer on the screen and is
used to perform such tasks as selecting icons,pointing
and moving objects on the screen.Inside
the Mouse
are moving components allowing the input of data
making your computing easier and more fun.
The get the mouse to perform
the desired task,you
place the pointer in the desired location and press
one of the buttons to start the operation of the program
you selected.
The mouse is moved on a
mouse pad and this
movement is tracked by four components inside.As
you can well image,this device get its name by the
shape and the cable or tail it has.
THE TYPES OF MICE
Serial
mice connect directly
to the RS-232C serial
port or a PS/2 port and this is the connection the
average computer will have.
The USB or
Universal Serial Bus mice connects to
your USB port,as
you would expect.All new computers
will have a USB Port and these ports will allow you
to connect every device with a USB connector.
Optical
Mice shines a beam of infrared light on a
special mose pad which contains a grid.Two beams
of infrared light are shot at right angles to each
other onto the mouse pad.The beam is reflected
onto a photo detector and onto the pad.
COMPONENTS OUTSIDE THE MOUSE
This device normally will have
two or three buttons on
the top that we push down to give commands.The
middle button on a three button mouse can be used
to do such tasks as double clicking icons.
Instead of double clicking
the left button on the standard
two button mouse,you can click the center button on
the three button mouse which may be a little faster.
The movement of the move is
sent to the computer
by way of Four Pin Interface Cable.This is where
information is transferred from the mouse to the PC.
COMPONENTS INSIDE THE MOUSE
When we move the mouse,a
ball underneath rolls in
the direction of the movement.This moves a roller which
moves the chopper gear.These components are
housed inside a
cavity underneath the mouse.The mouse
ball is the main component inside and allows
the user to move the mouse cursor on the screen.
The cursor would be motionless
without the ball.And
the ball uses two Choppers
and Gears to transmit
its movement to the computer.
SOFTWARE TO SETUP THE MOUSE
When you purchase your mouse,it
will, in most cases,
come with a floppy disk containing the device driver.
This software communicates with the computer and
your operating system will most likely have this utility
installed within its database.
Use the software on the diskette
over any utility that
your operating system may offer.Once your mouse
is performing the way it should,visit its supporting
web site and download any new device driver for
your particular mouse.
Special software may be needed
for the Optical,
and the cordless mouse.As with the mechanical
mouse,download updates from their supporting
web sites once you are up and running.
While understanding your mouse
may seen to be
such a big deal,learning about each and every
component of your computer will boost your PC
know how and help you save big on future PC
repair costs.
