Nerve (Definition) The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the copper (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites.
The 568A Commercial Building Wiring Standard of the Electronic Industries Association and the Telecommunications Industries Association (EIA/TIA) specifies the type of UTP cable that is to be used in a variety of building and wiring situations. The objective is to ensure consistency of products for customers.
UTP, using the 10BaseT specification, is the most popular type of twisted-pair cable and is fast becoming the most popular LAN cabling. The maximum cable length segment is 100 meters, about 328 feet. Traditional UTP cable, as shown in Figure 2.13, consists of two insulated copper wires.TP cable uses a woven copper-braid jacket that is more protective and of a higher quality than the jacket used by UTP. Figure 2.15 shows a two-twisted-pair STP cable. STP also uses a foil wrap around each of the wire pairs.
