A NIC (Network Interface Card) provides a dedicated network connection to the computer it’s installed on.  Without it, a computer could not connect to a network. It can be used in both wired and wireless communications, providing both a physical layer and data link layer device. 

When scaling cloud workloads, Turbonomic uses maximum supported NICs as a property of an instance type, and recommends the cheapest instance type that will meet a workload’s demand.
