What is the fundamental difference between Go Back to N and Selective Repeat Algorithm. Assuming a window size of 4, draw a message flow diagram for the scenario of packet 3 getting lost in the transmission of packets 0 through 5 from the sender side TCP layer to receiver side TCP layer using selective repeat algorithm. Discuss the maximal window sizes in the an N-bit long sequence number field for the Go Back to N and Selective Repeat Algorithms.

This is a computer networks question!
