Network Interface Card (NIC)
Explanation:
Also called Ethernet Card, the Network Interface Card (NIC) allows a computer or any device to make wired or wireless connections with other devices in a network. This connection made possible by the NIC allows the device to send and receive messages in the network.
An application of this is seen in Internet of Things(IoT) where devices communicate with one another. This is actually possible because all of the devices one way or the other have a network interface card.
