What is the difference between TCP half-close and full-close?
Correct! Well done.
Incorrect.
The correct answer is B) Half-close: one side finishes sending and sends FIN while still receiving (unidirectional close); full-close: both sides send FIN (4-way handshake)
B
Correct Answer
Half-close: one side finishes sending and sends FIN while still receiving (unidirectional close); full-close: both sides send FIN (4-way handshake)
Explanation
TCP teardown uses a 4-way handshake: FIN→ACK→FIN→ACK. Each side independently closes its sending direction, allowing half-duplex close when one side is done sending but still receiving.
