Selective Repeat Automatic Repeat reQuest (ARQ) offers several advantages, including improved efficiency in data transmission by only retransmitting erroneous packets rather than all packets after the error. This approach minimizes bandwidth usage and reduces latency, especially in high-speed networks where packet loss can occur. Additionally, it allows for better utilization of network resources, as multiple packets can be in transit simultaneously, enhancing overall throughput. Overall, Selective Repeat ARQ strikes a balance between reliability and performance in data communication.

Discuss about the difference between go-back-n ARQ and Selective Repeat ARQ?
Go-Back-N ARQRetransmission begins with the last unacknowledged frame even if subsequent frames have arrived correctly .duplicate frames are discarded.Go-back-n ARQ -- Receiver must get Frames in correct orderSelective Repeat ARQOnly the unacknowledged frame is retransmitted.It may be (slightly) more efficient than Go-back-n ARQ, but also much more complicated.Selective repeat ARQ -- correctly-received out-of-order Frames are stored at Receiver until they can be re-assembled into correct orderHamida Almangush

Advantages and disadvantages of selective breeding in English Bulldogs?
The advantages of selective breeding include producing a dog that meets the standard of the breed. Disadvantages include producing dogs with very short faces, squat legs, and large bodies.
What are the advantages and disadvantages of the Selective Repeat protocol in comparison with Go-Back-N?
Using the Go Back N protocol for error control means that if a timeout occurs, then all unacknowledged packets are resent, where with selective repeat, only those packets that were unacknowledged. This allows the Go Back N to use cumulative acknowledgements, creating a faster data flow, but this also means that in the case of an interruption, the system is slower to recognize this and then time is lost for the retransmission since the last cumulative ack.
