What is the difference between a standard mouse and an optical mouse? - KB Article - 168660
Verify correct mouse specs.
The only difference between a standard and an optical mouse is the fact that a standard mouse uses a trackball, whereas the optical mouse uses a sensor. The Optical Sensor(Figure 2) tracks pointing device movement without the standard ball and moving parts, providing increased control and precision. The two buttons act as normal mouse buttons. The roller only acts to scroll through a document. It does not act as a third button. Both still have the standard cable. (Figure 1)
