Computer Science for IGCSE & O level - Data Transmission (Section 1 - No. 44)

In an ARQ system, what happens if the sender does not receive an acknowledgment (ACK) within a specific time limit?
The sender immediately stops transmitting data.
The sender resends the data.
The receiver sends a negative acknowledgment (NAK).
The receiver discards the data.

توضیح

If an ACK is not received within the timeout, it generally implies that the data was not received correctly, so the sender resends the data.
