Is Ethernet part of TCP IP stack?


Ethernet and TCP/IP Protocol

Ethernet is a layer 2 data link protocol that is widely used with the TCP/IP protocol, which resides at layers 3 and 4.

Layering Approach in Networking

Layering allows standards to be put in place and simply adapted as new hardware and software is developed. The move from IPv4 addressing to IPv6 affects only the network layer – the other layers remain unaffected, enabling improvements to be made without having to redefine whole communication methods.

TCP/IP Model

TCP/IP model is defined with 5 layers:

  • Application layer
  • Transport layer
  • Network layer
  • Data link layer
  • Physical layer

TCP/IP Protocol Stack for Internet

The Internet Protocol layer in the TCP/IP protocol stack is the first layer that introduces the virtual network abstraction that is the basic principle of the Internet model.

TCP/IP Layers and Working

There are four layers of the TCP/IP model: network access, internet, transport, and application. Used together, these layers are a suite of protocols. The TCP/IP model passes data through these layers in a particular order when a user sends information, and then again in reverse order when the data is received.
