Is Ethernet a protocol?

Last updated on November 20, 2022

        When I googled I found a lot statements about this. Like..
  • Ethernet is not an application protocol. But I'd still give it the description "protocol". A network protocol defines rules and conventions for communication between network devices.

  • Ethernet is an entire communication stack

  • Ethernet is a family of computer networking technologies for LANs and MANs

  • Ethernet is just the Physical layer and the Data Link layer. By itself Ethernet does nothing; it’s just the “pipe.”

  • Wholehearted agreement that Ethernet is NOT a protocol. Ethernet is not much different than say RS-485. I use the analogy that Ethernet is the express service for sending packages while serial is dial-up modem or truck transport. The Sea Container or pallet (the packet) is oblivious to how it is being carried.

I'm confused by reading these all. Can just help me? Can we say Ethernet as a protocol?
