NIC in OSI Model

[Jimmy Lio]

Which layer does a NIC belong to in OSI model?

Jimmy

[Hayl]

i think it's the hardware layer

[rtr]

i think layer 2 but here (http://webopedia.internet.com/quick_ref/OSI_Layers.asp) is a link that might help

[toolio]

I believe that nics work define both layers 1 and 2


layer 1 - Physical layer, like rj-45 twisted pair

layer 2 - actually packaging bits for transmission



Not positive though

Toolio is correct, it is both layer 1 and 2.
Another important part of layer 2 is the MAC (Media Access Control) i.e. hardware address.
Network communications would not be possible without it.
