Three main functions of the data link layer:

A _______ error means that two or more bits in the data unit have changed.

Guard bands increase the bandwidth for ______

In _________ method, the sender can transmit several frames.

Regulation of rate of transmission of data frames is called _______.

Which error detection method uses parity bits?

In CRC method, what is CRC?

In ___________ ARQ, only the unacknowledged frame is retransmitted.

If there is change is single bit it is called _______ error.

ENQ/ACK is a line discipline method used in _______ connections.

In _________ a block of bits is divided into rows and redundant row of bits is added to the whole block.

Both Go-back-N and Selective Reject protocols use _____ protocol.

The redundant bit is called _____

The modulation technique that requires a carrier signal is ______.

VRC can detect ___________ bit error

Errors where more than 1 bit is inverted are called ______.

Error detection is done at __________ layer.

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

ARQ stands for _________.

Both Go-Back-N and Selective-Repeat Protocols use a _________.

In the _________Protocol, if no acknowledgment for a frame has arrived, we resend all outstanding frames.

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

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