An optical mouse uses a laser to detect the mouse's movement. The laser illuminates the surface beneath the mouse, and the sensor detects the reflection of the light to track the movement. This allows for more precise tracking compared to mechanical or optomechanical mice, which use a rolling ball or a combination of a ball and optical sensors. Wireless mice, on the other hand, refer to the method of connectivity and do not determine the type of sensor used.
10.
Which type of monitor produces an image by manipulating light within a layer of liquid crystal cells?
Correct Answer
B. LCD
Explanation
An LCD (Liquid Crystal Display) monitor produces an image by manipulating light within a layer of liquid crystal cells. Unlike CRT (Cathode Ray Tube) monitors, which use electron beams to generate images, LCD monitors rely on liquid crystals to control the passage of light through the cells. Gas plasma monitors, on the other hand, use a different technology altogether, where tiny cells of ionized gas emit ultraviolet light to create the image. Therefore, the correct answer is LCD, as it specifically mentions the type of monitor that uses liquid crystal cells to produce images.
11.
