OSI and TCP/IP Layers
The OSI hasn't changed from the time I first picked up the ICND1 book years ago. It is still the same. The thing that I found odd is the TCP/IP model. Years ago it was Application, Transport, Internet and Network Access but now after watching a Bryant video and doing some research, it seems like it now morphed into Application, Transport, Network, Data Link and Physical. When did this happen? I know how they all line up with each other (new and old) but am curious what brought around the change?
