RJ-45 stands for Registered Jack-45.
RJ-45 is an eight-wire connector, which is commonly used to connect computers on the
local area networks (LANs) especially Ethernets.
Ethernet is basically a LAN architecture developed by Xerox Corp along with DEC and Intel. Ethernet uses either a
bus or star topology and supports the
data transfer rates of upto 10Mbps.
The RJ-45 connector looks very much similar to the standard telephone connector (RJ-11 connector), but it is wider than the RJ-11 connector, as it
houses eight wired instead of four.
The RJ-45 connectors are used to connect computers in Ethernet LANs.
