Appendix D: Working with Coaxial Cable

Coaxial cable is a common type of cable used for network data transmission. In coaxial cable, an insulated wire runs through the middle of the cable and a second wire, called the shield, surrounds the insulation of the inner wire like a sheath. The outer insulation jacket wraps around the second wire.
