View solution

Q. _______ control refers to a set of procedures used to restrict the amount of data that the sender can send before waiting for acknowledgment.

View solution

Q. _________control in the data link layer is based on automatic repeat request, which is the retransmission of data.

View solution

Q. In Stop-and-Wait ARQ, we use sequence numbers to number the frames. The sequence numbers are based on __________arithmetic.

View solution

Q. In Stop-and-Wait ARQ, the acknowledgment number always announces in ______ arithmetic the sequence number of the next frame expected.

View solution

Q. In the Go-Back-N Protocol, if the size of the sequence number field is 8, the sequence numbers are in ________ arithmetic.

View solution

Q. Stop-and-Wait ARQ is a special case of Go-Back-N ARQ in which the size of the send window is 1.
