A Network Interface Card (NIC) is a crucial piece of hardware that links your computer to a network and is utilised for networking connectivity. Almost every networked device, including printers, phones, and scanners, can have a NIC. Every NIC has a distinct hardware address that serves as the NIC's means of identification.
A network connection is made possible via a network interface card (NIC), a piece of computer hardware. A network interface controller card, expansion card, computer circuit board, network card, LAN card, network adapter, or network adapter card are further names for it (NAC).
An Ethernet controller that is built into the motherboard of a computer is known as an integrated NIC (Network Interface Card). The motherboard of the majority of modern computers has a network interface built right in. When two computers are physically linked or utilising a network switch, network cards can interact with one another over the same network.
