A CRT device is different from a CCD device in what way?

A.
A CRT is an analog display; a CCD is a digital camera

B.
A CRT is a digital display; a CCD is an analog camera

C.
A CRT is an analog camera; a CCD is a digital camera

D.
A CRT is a digital camera, a CCD is an analog camera

Explanation:
Answer C is correct; a Cathode Ray Tube camera is analog. A Charge Coupled Discharge camera is digital.

Incorrect Answers and Explanations: A, B, and D: Answers A, B, and D are incorrect. Answer A is a trick answer: a CRT may also be a display, and the question is intentionally vague on which it is asking about (display or camera). CRT and CCD are the primary forms of cameras, so it is implied that CRT means camera in this context. B and D are incorrect because CRTs are analogue and CCD is digital.
