A Network Interface Card (NIC) is a device that allows computers to be joined together in a network, typically a Local Area Network (LAN). Networked computers communicate with each other using a certain protocol for transmitting data packets between the different machines. The Network Interface Card acts as an interpreter, allowing the machine to both send and receive data on a LAN. Information Technology (IT) specialists often use these cards to setup wired or wireless networks.
One of the most common languages or protocols used with a LAN is Ethernet. When building a LAN, a Network Interface Card is installed in each computer on the network and each one must use the same architecture. For example, all the cards must be Ethernet cards, Token Ring cards, or an alternate technology for proper use.
An Ethernet network interface card is installed in an available slot inside the computer, typically on the motherboard. The NIC assigns a unique Media Access Control (MAC) address to the machine, which is used to direct traffic between the computers on a network.
