CompTIA A+ Core 1 (220-1201) — Question 159

Which of the following is used to register inputs on a touch-screen monitor?

Answer options

• A. Inverter
• B. Digitizer
• C. OLED
• D. LCD

Correct answer: B

Explanation

The correct answer is B, Digitizer, as it is specifically designed to convert touch input into digital signals that the device can interpret. The other options do not serve this function; an Inverter is used for power conversion, OLED refers to a display technology, and LCD is another type of display that does not have the capability to register touch inputs directly.
