1 Answer

Answer :

Advantages of Optical mouse 1. No moving parts: thus less wear & tear 2. Lesser chance of failure due to dust: no interference with tracking sensors. 3. The cursor accuracy of an optical mouse is typically high as it can analyze changing positions at 700 mm/sec and read up to 200 to 300 dots per inch. This means that it reads its location fast with high precision. 4. The optical mouse can be used on almost any surface as long as the laser can read the surface it is on.: 5. Less maintenance, no cleaning needed.
