The sender transmits one frame and waits for an ACK before sending the next. Pros: Simple implementation.

Automatic Repeat Request (ARQ): Reliable Data Transmission 1. Introduction The sender transmits one frame and waits for

Low throughput on links with high propagation delay, as the channel remains idle while waiting for ACKs. 3.2. Go-Back-N ARQ (GBN) The sender transmits one frame and waits for

ARQ increases latency due to retransmissions, making it less suitable for real-time applications like VoIP. The sender transmits one frame and waits for
