Analog to Digital

Q1: A data conversion system may be used to interface a digital computer system to:

A an analog output device

B a digital output device

C an analog input device

D a digital printer

ANS:A - an analog output device

A system can give digital or analog output as required. Input is analog in nature which is to be converted necessarily. Thus, the word 'may' tells us that a data conversion system may be used (for output), not necessarily.
