SP SHIELD PLUS RJ-45 CONNECTOR 100PCS NETWORK INTERFACE CARD Lan Adapter(150 Mbps)

A registered jack (RJ) is a standardized physical network interface for connecting telecommunications or data equipment. The physical connectors that registered jacks use are mainly of the modular connector and 50-pin miniature ribbon connector types.Cables can transmit information along their length. To actually get that information where it needs to go, you need to make the right connections to an RJ45 connector. Your cable run needs to terminate into a connector, and that connector needs a jack to plug into. Registered Jack 45 (RJ45) is a standard type of physical connector for network cables. RJ45 connectors are commonly seen with Ethernet cables and networks. Modern Ethernet cables feature a small plastic plug on each end of the cable. That plug is inserted into RJ45 jacks of Ethernet devices. The term “plug” refers to the cable or “male” end of the connection while the term “jack” refers to the port or “female” end.
