WebThe OSI (Open System Interconnection) Reference Model is a layered network model. The model is abstract: we do not directly run the OSI model in our systems (most now use the TCP/IP model); it is used as a reference point, so “Layer 1” (physical) is universally understood, whether you are running Ethernet or ATM, for example. “Layer X ...
