Answer 2

TCP provides reliable communication using setting up a communication channel between sender and receiver.

(Option A)

• TCP delivers dependable communication using a feature known as Positive Acknowledgement with Re-transmission (PAR).
• A segment is the transport layer's Network Protocol Unit. Now, a PAR-enabled device will retransmit the block of data till it obtains an acknowledgment.
• If the data unit delivered at the receiver's end was defective, the segment is discarded. As a result, the sender must send the data unit for which no affirmative acknowledgment was received.
• The above procedure showed that the three segments are transferred between both the sender (client) and the receiver (server) for a reliable Network interface to be created.
• As a consequence, TCP ensures reliable communication by establishing a channel of communication between the source and the destination.
