... 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-to-network, internet, transport, and application. However, when TCP/IP is compared to OSI, we can say that the TCP/IP protocol suite is made ...

The term “peer” means every implementation of some layer is essentially equal to all others. There is no “master” system at the protocol level. ...
