A CDU computer screen that senses finger pressure is:

A CDU computer screen that senses finger pressure is:

• A. A digitizer
• B. An intelligent terminal
• C. A scanner
• D. A touch screen

Answer: (D)

Touch-sensitive displays let you interact by touching the display surface itself, with the screen detecting the finger's contact and translating it into input. A CDU screen that senses finger pressure does exactly that, so it’s a touchscreen. A digitizer is a separate input surface used to capture coordinates from a stylus or finger and isn’t the display itself. A scanner converts printed material into a digital image, not interactive input. An intelligent terminal is a computing device with input/output capabilities, but the term doesn’t imply touch sensing on the display.
