Detailed Answer
(b) The requirement is to identify the most frequent
current format for computer processing of data. Answer (b) is
correct because most current computers process data using a
digital approach in that they represent information by numerical
(binary) digits. Answer (a) is incorrect because analog computers,
which represent information by variable quantities (e.g.,
positions or voltages), are less frequent in practice than digital
computers. Answer (c) is incorrect because “memory enhanced”
is not a format for processing information. Answer (d) is incorrect
because “organic” is not a format for processing information.
