Topics discussed in this section:

  • Physical and Data Link Layers
  • Network Layer
  • Transport Layer

TCP/IP PROTOCOL SUITE
The layers in the TCP/IP protocol suite do not exactly match those in the OSI model. The original TCP/IP protocol suite was defined as having four layers: host-tonetwork, internet, transport, and application. However, when TCP/IP is compared to OSI, we can say that the TCP/IP protocol suite is made of five layers: physical, data link, network, transport, and application.
