Question

We know that Stop and Wait, Go-Back N, Selective Repeat are the flow control methods. Now, each of these methods incorporates certain strategies for packet loss, duplicate packet detection.

We also know that recovery of the lost packet, duplicate packet detection comes under Error control, right? So, can we conclude the statement? -> "Flow control methods are using error control techniques"

"We also know that recovery of the lost packet, duplicate packet detection comes under Error control, right? "

How can you say ??

 recovery of lost packet  which is depend on timeout timer which is not any type of error control(i.e retransmission) and duplicate packet problem can be detected by using sequence number which is not type of any error control.Error control means there is any error inside the packet but flow control is related to sending of packet from sender to reciever in proper manner.
