Match List I with List II.

LIST I (Data Transmission modes in computer network)		LIST II (Description)
A.	Simplex	I.	Data can be sent and received at the same time.
B.	Duplex	II.	Data can only be sent or received.
C.	Half-duplex	III.	Data can be sent and received but not at the same time.

Choose the correct answer from the options given below:  

Simplex

Data can only be sent or received.

In a simplex mode of data transmission, data can flow in only one direction, either from sender to receiver or vice versa, but not both simultaneously.

Duplex

Data can be sent and received at the same time.

In a duplex mode of data transmission, data can be sent and received at the same time, allowing for bidirectional communication between sender and receiver.

Half-duplex

Data can be sent and received, but not at the same time.

In a half-duplex mode of data transmission, data can be sent and received, but not simultaneously.

The communication alternates between transmitting and receiving, allowing bidirectional communication but not simultaneously.
