Transmission of information in a communications link is defined by three protocol techniques: half duplex,full duplex,and __________.
A)asynchronous
B)framing
C)simplex
D)synchronous

Question

Quizplus · Accepted Answer

The two given options, half duplex and full duplex, are both examples of bidirectional communication where data can be transmitted in both directions. Simplex, on the other hand, is a unidirectional communication method where data can only flow in one direction. Asynchronous and synchronous refer to how data is transmitted in time, and are not related to the direction of data flow. Framing is a technique used to encapsulate and separate data at the physical layer and does not relate to the transmission of data in a communications link. Therefore, the correct answer is "C) simplex", which is the communication method where data can only flow in one direction.
