 | | The internet protocol suite can be described by analogy with the OSI model, which describes the layers of a protocol stack, not all of which correspond well with internet practice. |
 | | The Physical layer describes the physical characteristics of the communication, such as conventions about the nature of the medium used for communication (such as wires, fiber optic links or radio links), and all related details such as connectors, channel codes and modulation, signal strengths, wavelength, low-level sychronization and timing and maximum distances. |
 | | Applications most commonly run on TCP or UDP, and are often associated with a well-known port number. |
