NIC
Network Interface Card
A NIC is an interface device that connects a server to a network.
In context
One NIC may have multiple physical ports, and the operating system may show additional logical interfaces. Distinguish the number of cards, ports, and logical interfaces.
Example
With one hypothetical 2-port NIC, a physical card failure may affect both ports together.
Key distinction
Check the failure domains of the card and connection paths as well as the port count.
