NIC Card Place in the OSI?

| Okay, I'm kind of confused here...
My Boson test says the NIC is located on the Data Link Layer (2) while my other resources say it's located on the Physical Layer (1) but never both...
Which is it? I always though it was located in the Physical Layer because it just sent the electrical signals back and forth...
Can anyone clear this up for me? Thanks. | |

| NIC cards are data link layer devices.when you think of NICs think of the mac addresses burned into the cards.They are part of the data link layer or layer 2 of the OSI. | |

| technically, you're both right. The NIC provides electrical access to transmission media on the physical layer as well as MAC addressing to uniquely identify each node in a network at the Media Access Control layer which resides at the Data Link Layer. The data link layer is concerned with physical addressing, network topology, physical link management, error notification, ordered delivery of frames, and flow control.
This is an on-going debate and I'm sure several people will have their say... | |

| I just hope I don't encounter that on the test... thank you for the quick reply. | |

| actually, it's a NIC, not a NIC card 
This aside, the NIC is at layer 1... the NIC driver is at layer 2. For CompTIA tests, the NIC is a layer 1 device. I hope this helps  | |

| Certain parts of the NIC function at layer one, while other parts function at layer two. So technically, it does function at both layers. | |

You're welcome to your opinion
But this being the Net+ forum, I am just trying to give a CompTIA Net+ answer, if you catch my drift... | |

| I understand, but according to the A+ exam, the NIC does function at both layers. This is also taught in military computer courses. If need be, I can gather the resources and post them here. I've also taken the Net+ exam and I believe the same holds true for that one too. |
