NIC

A network interface card or NIC is like the computer's translator, allowing it to communicate with other computers and devices over a network.

The NIC converts data from the computer into a format that can be transmitted over the network and vice versa. They can be either wired (Ethernet) or wireless (Wi-Fi).

NICs also handle addressing, which are like digital IDs for computers over a network. This allows data to be delivered to the correct destination.
