Block Diagram
The transport and network layers contain:
z Two general sockets that provide connectivity between the application layer and the transport layer.
z TCP/UDP module that allows for reliable (retransmission) and unreliable (no retransmission)
datagram deliveries.
z IP module that provides connectionless packet delivery.
z PPP module that provides point-to-point connection link between two hosts.
