(a) The requirement is to identify an advantage of using
the Internet for electronic commerce EDI transactions as compared
to a value-added network (VAN). Answer (a) is correct
because such simultaneous processing of transactions is more
likely under an Internet system in which lines are often available
at a fixed or nearly fixed rate. Answer (b) is incorrect because the
Internet itself will not automatically prepare such batches. Answer
(c) is incorrect because an Internet system will not ordinarily
have superior characteristics regarding disaster recovery.
Answer (d) is incorrect because translation software is needed
both for Internet and VAN systems.
