The transport and network layers contain:


Two general sockets that provide connectivity between the application layer and the transport
layer.


TCP/UDP module that allows for reliable (retransmission) and unreliable (no retransmission)
datagram deliveries.


IP module that provides connectionless packet delivery.


PPP module that provides point-to-point connection link between two hosts.
