For communications, there is another type, following the RJ-w specifications. It s a rather strange-looking connector, with a tab on the bottom and small brass connectors on top. These connectors are easy to identify—just look at the connectors on your telephone. The connector on the end of the cord that runs from the phone to the wall is an RJ-11 connector. The connector on the end of the cable that runs from your handset to your phone is the smaller, RJ-12 connector. You may have seen the type of network cable that uses an RJ-45 connector, which looks about twice as big as an RJ-11 connector. 

You have put the network together in a topology. You have told the network how to communicate and send the data, and you have told it how to send the data to another computer. You also have the communications medium in place. The next problem you need to solve is how do you put the data on the cable. What you need now are the cable access methods, which define a set of rules for how computers put data on and retrieve it from a network cable. The four methods of data access are... 

UTP Acronym for unshielded twisted-pair. A type of unshielded network cable that contains multiple conductors in pairs that are twisted around each other. 

Interfaces (I/O [input/output] cards, dedicated/network, cabling, speed)... 

Wide Area Networks (WANs) - No amount of redundancy within the data centre will protect the service if someone conducting highway maintenance nearby puts a spade through the network cable. Resilient systems often have multiple outward-facing network connections travelling in different geographical directions. 

The controller with input/output signals. It is connected to the device via the 8 input and output pins. It is also connected to the router of the cell through a network cable. 

Major communication and services infrastructures (e.g., roads, bridges, railroads, telephone networks, radio broadcasting networks, cable networks, the Internet, etc.) are built only once every few decades. It is helpful to keep this perspective in mind when thinking about the next-generation wireless network. 

Each element of the matrix contains a valne indicating the level (from 0 to 1) of the dependency associated to a couple of elementary areas (e.g. from area B3 to A3) as a synthesis of dependencies related to the physical structure of the network (cables) and vulnerability in front of given component failure (cabin black-out). A probability of interoperability equal to 1 is assumed for indicating the total inoperability of the coimected lines in front of a cabin blackout. 

Multiple data carrier, multiple network cables, or direct physical access...
