title: Ethernet and OSI Model
body: <p>I have a dumb question, first of all sorry for that. i am learning now 7 OSI Layer models and i stumble across one thing. The Ethernet which is in the second Data Link Layer provides the end-to-end connection via LANs, right? Does it mean that even if i connect to Internet thru WiFi, somewhere my connection is running thru LANs? </p>
  
  <p>Thanks </p>
