Network Cards (NIC)

clipped from www.proprofs.com Network card is a card that is installed on a motherboard of a computer, which enables communication with other computers. Often abbreviated as NIC (Network Interface Card), an expansion board you insert into a computer so the computer can be connected to a network. Most NIC's are designed for a particular type of network, protocol, and media, although some can serve multiple networks. The PCs are usually connected by some type of cabling, usually an advanced type of phone-cable or coaxial cable. Network cards (NIC's) provide the interface between the network and computer's. A NIC can be recognized by any of these connectors: a RJ45, BNC, 15-pin female DB, or 9-pin female DB. It is very common to see NIC's with more than one type of connector. Probably the most common combination: NIC has an RJ-45 and a BNC.
