In questions (a), (b), and (c) below, identify all the eventsthat subsequently happens at both Host A and Host B in response tothe error condition. For example, state if the Host discards frames(e.g., Host X discards frames 1 and 2), if a control message isreturned (e.g., NAK N sent), and if data is resent (e.g., frames 1and 2 are resent). Assume ACK N acknowledges frames throughsequence numbers N-1.
a) Given a data link with a stop and waitARQ protocol. Host A sends frame 0 to Host B. Host B ACKs the frameand the ACK is lost
b) Given a data link with a sliding windowARQ protocol that uses Go Back N with a 3-bit sequence number(sequence numbers 0 – 7).
(1) Host A sends four frames with sequence numbers 0, 1, 2, and3 to Host B. Frame 1 arrives damaged.
(2) Host A sends four frames with sequence numbers 0, 1, 2, and3 to Host B. Host B returns an ACK of all of the frames sent byHost A and the ACK is lost.
c) Given a data link with a sliding windowARQ protocol that uses Selective Reject with a 3-bit sequencenumber. Host A sends frames with sequence numbers 0, 1, 2, and 3 toHost B. The second frame sent by Host A is lost.
c-2) What would be the actual bits sentover the communications channel for the following HDLC frame:01111110 00011111 00001111 11111100 01111001 11110000 01111110
