After transmitting one packet, the sender waits for an acknowledgment (ACK) from the receiver before transmitting the next one.

Detailed explanation-2: -Stop-and-wait ARQ, also referred to as alternating bit protocol, is a method in telecommunications to send information between two connected devices. It ensures that information is not lost due to dropped packets and that packets are received in the correct order.

Detailed explanation-3: -In Stop and Wait protocol, Acknowledgement type is individual. In Go-Back-N protocol, Acknowledgement type is cumulative. In Selective Repeat protocol, Acknowledgement type is individual. At the receiver end of the Stop and Wait protocol, no specific order is required.
