the theoretical measure of how much data could be transferred from a source to its destination
Bandwidth
The actual measure of how much data is successfully transferred from a source to its destination
Throughput
a designation given to a particular category that provides the ability to understand the bandwidth and the cable type to be used

the ability to take send and receive pins from one cable and swap those on the other end
Crossover Cable
is an automated way to electronically simulate using a crossover cable
a medium dependent interface crossover (MDIX)
a cable rating that specifies that a cable has a stronger sheathing and jacket that can withstand more extreme weather conditions
Direct Burial
a special coating put on a UTP or an STP cable that provides a fire retardant chemical layer to the outer insulating jacket
are for ceilings, walls, raised floors, or air ducts
Plenum cable
