Which standard govern parallel communications?

A. RS232

B. RS-232a

C. CAT 5

D. IEEE 1284

E. None of the above

Answer: Option D

Solution(By Examveda Team)

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.
