Question

which type of touch screen is made up of two layers that come into contact when the user presses on the screen?
resistive
capacitive
infrared
surface acoustic wave (saw)

Explanation:

A resistive touch screen consists of two layers (a flexible layer and a rigid layer) with a gap between them. When pressure is applied (e.g., by a finger or stylus), the two layers come into contact, creating an electrical connection that registers the touch location. Capacitive touchscreens work based on electrical capacitance changes (no physical contact of layers in the sense described here). Infrared touchscreens use infrared beams to detect touch (no layer - contact mechanism). Surface acoustic wave (SAW) touchscreens use ultrasonic waves (again, no layer - contact as per the question's description).

Answer:

Resistive
