An IS auditor needs to link his/her microcomputer to a
mainframe system that uses binary synchronous data
communications with block data transmission. However, the IS
auditor's microcomputer, as presently configured, is capable
of only asynchronous ASCII character data communications.
Which of the following must be added to the IS auditor's
computer to enable it to communicate with the mainframe system?
A. Buffer capacity and parallel port
B. Network controller and buffer capacity
C. Parallel port and protocol conversion
D. Protocol conversion and buffer capability
Answer / guest
Answer: D
For the IS auditor's microcomputer to communicate with the
mainframe, the IS Auditor must use a protocol converter to
convert the asynchronous and synchronous transmission.
Additionally, the message must be spooled to the buffer to
compensate for different rates of data flow.
