NIC interface type(NETWORK INTERFACE CARD)

NIC: the
NIC in charge of the cable interface type is with the network connection, so it must have an interface cable to connect through it and other computer network equipment. Different network interface for the different network types, the common interface Ethernet RJ-45 connector, a thin coaxial cable, BNC connectors and thick coaxial, AUI interface, FDDI interfaces, ATM interfaces. And some network cards in order to apply to a wide range of application environments, provide two or more types of interface, if the card will also provide RJ-45, BNC interface or AUI interface.

(1) RJ-45 interface
is the most common type of card is the most widely used type of interface card, which is mainly due to the popularity of the twisted-pair Ethernet applications. This RJ-45 connector type of card is used in Ethernet twisted pair transmission medium, its interface is similar to a telephone interface RJ-11 RJ-45 is the 8-cell lines, and telephone The line interface is a 4-core, and usually only take two core lines (ISDN phone line connected to the 4-wire). Preliminary judgment by the two light colors work state of the network card on the card also comes with two status indicator light. (2) BNC connectors, this interface card used in Ethernet or Token Ring using thin coaxial cable as the transmission medium, the network card of this type of interface is rare, mainly because with a thin coaxial cable as a transmission medium the network is relatively small. (3) AUI interface of this type of interface card that applies for the transmission medium to thick coaxial Ethernet or Token Ring, of this type of interface card is rare. (4) the FDDI interface of this interface card is adapted to FDDI, (Fiber Distributed Data Interface) network, this network has a bandwidth of 100Mbps, but it uses the transmission medium is optical fiber, so this FDDI interface card interface is optical interface. With the emergence of Fast Ethernet, it's speed superiority no longer exists, but it must be expensive optical fiber as the transmission medium's shortcomings and has not changed so very rare. (5) This type of interface of the ATM interface card is used in ATM (Asynchronous Transfer Mode) network of optical fiber (or UTP). It provides the physical transmission speed up to 155Mbps.
