| Hey guys, I have a Cisco book that states a NIC is a Layer 2 device
because of it's unique MAC Address and a Layer 1 device because it
handles signaling and encoding. My question is which one is it (I
think its a Layer 2 device) and what happens if I see this question on
the Network + Exam and one of the possible answers is Layer 1 and
another possible answer is Layer 2? I wouldnt be having a problem
with this question except in other books I am using to study for the
Network+ (such as Exam Cram 2), they state that a NIC is a Layer 1
device. Any light is appreciated!! Thanx, anna c

NIC is layer two.
This was hashed out recently.
Try to remember it as the highest layer the device can handle, such as a
router has layer one, two, and three, but it is a layer three device
because that is it's highest function.

| This is a question that will not die 
You will also see that most here will disagree. remember that you are reading a Cisco book meant to prepare you for a Cisco test, while you are actually studying for a CompTIA test. As far as the Net+ test is concerned, the NIC itsef is a layer one device, and the NIC driver is at layer two.
In the "real world", the NIC and the NIC driver are basically unusable without each other, therefore most people will tell you that the NIC covers both layer one and two functionalities.
I hope this helps. | |

Better yet, what Layer 1 devices do we have left? Cables? :-)
The answer to your question would be "All of the below"?

Following my reasoning, routers are layer three devices, NICs are layer two
devices, and layer one devices are "the physical layer".
I have no connection to CompTia, so I do not know there position on what
layer a NIC represents.

Agreeed.
My point was using freak's reasoning, a router is also a layer one device.
Enough from me. I'm done.
Cheers!

It all depends on who is asking the question, and what they want to
hear. Anyone who is married can understand that, I suppose... :-)

The only devices that can strictly be considered only layer 1 are those
that deal only with electrons or photons. So yes, cables and connectors
count. In terms of network interconnection devices, repeaters and hubs
are layer 1, as are transceivers, amplifiers and the like.
