Q9
Which standard govern parallel communications?
A.
RS232
B.
RS-232a
C.
CAT 5
D.
IEEE 1284
AnswerE.
None of the above
Answer: Option D
Solution
Answer: Option D
Solution:
The standard governing parallel communications is IEEE 1284.IEEE 1284 specifies the electrical and signaling characteristics of parallel ports, commonly used for connecting printers and other devices to computers.
RS-232 and RS-232a are standards for serial communication, not parallel communication.
CAT 5 is a standard for Ethernet cables used in networking, also not related to parallel communication.
Therefore, the correct option is IEEE 1284.
