Computer mice some in a number of varieties. You can find a computer mouse for just about any use. To figure out what kind of mouse would work best with your PC, you need to know your mouse options:

3. Mechanical Mouse
It contains a metal or rubber ball on its under side. When
the ball is rolled in any direction, sensors inside the mouse detect
this motion and move the on-screen mouse pointer in the same
direction

5. The optical-mechanical or optomechanical mouse consistsof a
ball that rollsoneof two wheelsinsidethemouse. Each wheel containsa
circleof holes, allowing an LED light to shinethrough and bedetected
by asensor. Asthewheel spinstheselightsrepresent an X or Y axis for

7. An optical computer mouse uses a light source, typically
an LED, and a light detector, such as an array of photodiodes, to
detect movement relativeto asurface.
It is an alternative to the mechanical mouse, which uses
moving partsto sensemotion.

9. LaserMouse
A laser mouse is a type of optical mouse that uses laser light to detect
mouse movement. Like all optical mouse, the laser mouse has no moving
parts inside. Laser is more accurate than the standard optical mouse design,
providing for up to 20x greater sensitivity and precision. This improved
sensitivity and precision can be key for gaming applications and graphical or
engineering design applications, wherepinpoint accuracy isimportant.
Laser mouse have a higher dpi, which means that they can track more dots
per inch, which in turn meansthat they'remoresensitive.
