Confusion between Ethernet, MAC, and data link layer
I'm studying for CCNA by one week, and in particular I'm in Chapter 1 (Introduction to networking basics). I understood that each layer has its protocols: Application-HTTP/FTP/..., Presentation-SSL/...,... However, I have a bit confusion about Ethernet and MAC :. MAC is a sub-layer of Data link layer (together LLC), ok, but is it even a protocol, right? Instead what is Ethernet?? A protocol? Another sub-layer?
