One of the most important accessories for networking computers together, are RJ45 cables. These cables have been around for many years, with some of these used for telephone sockets and dial-up internet connection (assuming one has a dial-up connection these days!). These are basically connectors which are not only useful for transferring data and information, but are also useful for allowing two or more machines or devices to communicate with each other at a fast rate of speed.



The RJ45 is basically a connector and allows for the network between each other to stay strong. The RJ in RJ45 stands for registered jacks, which put simply is an Ethernet cable that looks pretty similar to a telephone cable. The RJ11 is commonly used for telephone connections with the rJ45 used mainly for networking computers onto the local area network. The registered jack itself comes with a number of different interfaces, as is notable above.

There as mentioned RJ11, RJ14, RJ25 and many more. Each one functions in very different ways but are essentially designed for the same thing which is communication and networking. The rJ45 can be commonly referred to as the 8P8C connector, which stands for eight position eight contacts plug socket. The 8P8C when compared to a standard 6P6C connector, are extremely useful for making clear connections for communication. The 6P6C connector only has six connections and all of them contain conductors similar to the 8P8C connector.

One thing that both of these connectors do have in common is that they are both capable of making a strong connection for communication in the right sockets. Often it can be confusing to figure out what plug to use for which connection, therefore these devices are good to help make the right decision for the connection. They are also less bulky and require low maintenance than older cables that were once used for connection.

With the connector differences in mind the RJ45 has male and female connectors and are also used mainly in the US for telecommunications. It is better known as an Ethernet connection device, however, it can also be used for other connectivity. As the connections increase, the quality of the cable increases, with many of the cables using a low current and voltage rate. Furthermore this registered jack is far more diverse than the RJ11 that only uses two of four wires.

Older styles of connection for communication were not as aesthetically appealing as the cables designed now, as they were larger and bulkier. They were more difficult to maintain and used up far more power than needed. The newer connectors tend to be power efficient and do not need to be maintained.
