What is coaxial cable?

Answer / c.kumaresan
Coaxial cable is called "coaxial" because it includes one
physical channel that carries the signal surrounded (after
a layer of insulation) by another concentric physical
channel, both running along the same axis. The outer
channel serves as a ground. Many of these cables or pairs
of coaxial tubes can be placed in a single outer sheathing
and, with repeaters, can carry information for a great
distance.
