CompTIA A+ Core 1 (220-1101) — Question 452

Which of the following components enables finger-based screen input for two-in-one laptops?

Answer options

• A. Fingerprint scanner
• B. Digitizer
• C. Stylus
• D. Inverter

Correct answer: B

Explanation

The correct answer is B, Digitizer, as it converts the touch input from fingers into signals that the device can understand. A fingerprint scanner is used for authentication, a stylus is a tool for precise input, and an inverter manages power for the display, none of which directly facilitate finger-based input.
