Explain how the Transport layer uses several reliability measures.
What will be an ideal response?
The Transport layer use several reliability measures. Class 0 is the simplest protocol. It performs no error checking or flow control and relies on the Network layer to perform these functions. Class 1 protocol monitors for packet transmission errors, and if an error is detected, it notifies the sending node's Transport layer to resend the packet. Class 2 protocol monitors for transmission errors and provides flow control between the Transport layer and the Session layer. Flow control ensures that one device does not send information faster than can be received by the network or by the receiving device. Class 3 protocol provides the functions of Classes 1 and 2 along with the option to recover lost packets in certain situations. Finally, Class 4 protocol performs the same functions as Class 3, along with more extensive error monitoring and recovery.

Show that if longitudinal parity is used as an error detection code, values in a database can still be modified without detection. (Longitudinal parity is computed for the n-th bit of each byte; that is, one parity bit is computed and retained for all bits in the 0th position, another parity bit for all bits in the 1st position, etc.)
