Can you provide a context?  I have not seen such a setting.  A NIC can be dead (not functional) or alive (working).

I think it is just referring or related  to the NIC card or adapter is connected or  disconnected from the line (Alive/Dead), otherwise  it is hard to find its definition in  google search.

Could you provide more information ?

I have to admit to being confused by the question as well.  I normally think of functional NIC in three possible states:
Alive or active - The NIC is seeing and passing traffic.
Inactive - The NIC is not-disabled, but is not seeing or passing traffic.  This would normally be because there is no media connected or no wireless network available.
Disabled - The NIC is disabled, in hardware or by the OS.

I suppose 'Dead' could refer to either Inactive or Disabled NIC, but it's also possible that a 'Dead' NIC could refer to a NIC which is physically broken or for which the relavent operating system lacks proper drivers to interface with the card.

I am sorry, I think I misunderstood something about this term. It was indicating dead OR alive, which makes sense of course - not dead-alive. I am sorry to have wasted people's time. Thank you very much for your responses though.

So then as I said above (and others noted later) that the NIC is not functional (dead) or functional (alive).
