NIC -- OSI layer 1 or 2 ?

| Barry Watzman 2002-09-25, 4:28 pm |
| I'm seeing various texts some of which claim the NIC is at the OSI layer
1 (physical) and others saying layer 2 (Data link).
What is the consensus ?

Both layers. It has a Physical layer connection and a Data Link layer
address. Good luck on your exam.

| Well, actually, I agree with you, the NIC operates at both layer 1 and 2
(and certainly it's drivers are at level 2).
But .... if you get a multiple choice question and the only choices are
"level 1" and "level 2" ..... what's the consensus "right" answer FOR
THE TEST ?

Layer 2 but the exam doesn't try to split hairs.

| Would I be correct in saying that the highest
level would be the right choice? Since most
devices have a waterfall use of other layers,
like a router has a physical layer but works
up to layer 3.

That is the best way to describe it in my opinion. Thank you for the
Wednesday afternoon clarification.
