TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
