There are three general classes of media types: coaxial cable, twisted pair and fiber optic cable. Coaxial cable had suffered waning popularity, but is making a bit of a comeback with cable modem solutions. There are two types of fiber-optic cable: multi mode fiber and single mode fiber. Twisted pair is the most common type of computer network cabling. Twisted pair can be classified according to the value of the intrinsic impedance of the wire, and whether it is shielded or unshielded. Unshielded twisted pair, with an intrinsic impedance of 100 ohms, is the most common type of computer network cabling used today.
