ABSTRACT
Two basic steps must be completed to deliver data successfully between two Internet participants. First, it is necessary to transmit the data across the network to the appropriate host. Second, the data has to be transmitted within that host to the appropriate user or process. TCP/IP uses three schemes to accomplish these tasks:
1. Addressing IP addresses uniquely identify each host on the entire internet; TCP/IP relies on IP addressing to deliver data to the correct host on the network.
