marks$)$ Consider a system with a sender and a receiver. The sender frame sequence numbers take values from the set $0,1,2,3,4,5).$ Can go$-$back$-4$ ARQ protocol be used in this system? Can go$-$back$-3$ ARQ protocol be used in this system? Justify your answers. If go$-$back$-4$ ARQ and go$-$back$-3$ ARQ protocols can indeed be used in this system, will you use go$-$back$-4$ ARQ or go$-$back$-3$ ARQ protocol? Justify your answer.
