Answer: B
Parity bits are used to check for completeness of data
transmissions. Choice A is incorrect because check digits
are a control check for accuracy. Choice C is incorrect
because in one-for-one checking, individual documents are
matched to a detailed listing of documents processed by the
computer, but do not ensure that all documents have been
received for processing. Choice D (prerecorded input) is a
data file control for which selected information fields are
preprinted on blank input forms to reduce the chance of
input errors.
