NIC -- OSI layer 1 or 2 ?

| 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.

| Once again, as far as CompTIA is concerned, the NIC itself is layer one, and the driver is at layer 2. Then again, they are the guys that tell you that HTTP is a connection-oriented protocol... |
