Network Interface Card (NIC)

To connect a computer to a network, a network interface card (NIC) is essential. A network interface card or a LAN card plugs into a slot on motherboard to connect it to the LAN. For any computer, a network interface card (NIC) performs two crucial tasks and these are:

♦ Establishes the physical connection between the computer and a network and then manages that link.

♦ Translates digital computer data into signals (appropriate for the networking medium) for outgoing messages, and translates signals into digital computer data for incoming messages.
