The TCP/IP protocol suite is made of five layers: physical, data link, network, transport, and application.
The first four layers provide physical standards, network interface, internetworking, and transport functions that correspond to the first four layers of the OSI model.
The three topmost layers in the OSI model, however, are represented in TCP/IP by a single layer called the application layer.
Addressing
Three different levels of addresses are used in an internet using the TCP/IP protocols: physical (link) address, logical (IP) address, and port address.
The topics discussed in this section include:
Physical Address
Logical Address
Port Address
