Copper cable that includes one or more sets of cable pairs which have been molded into an insulating material and covered by a braided shielding conductor STP offers better noise protection than unshielded twisted pair (UTP) but is much more expensive and more difficult to use Commonly associated with early token ring networks
Shielded Twisted Pair - Twisted pair wiring with metallic shield surrounding the signal-carrying conductors in order to protect them from ambient noise in the form of EMI (ElectroMagnetic Interference) The outer shield may be in the form of a thin metallic mesh in the case of ScTP (Screened Twisted Pair), or a very thin metallic foil in the case of FTP (Foil Twisted Pair) The shield acts as an antenna, converting the noise into current flowing in the shield; it must be properly electrically grounded or the shield current actually will intensify the noise problem
Spanning Tree Protocol is used between bridges to detect and logically remove any redundant paths generated during the Bridge database creation process
Shielded Twisted Pair Two, or more, insulated wires that are twisted together and then wrapped in a cable with metallic braid or foil to prevent interference and offer noise-free transmissions Also refers to IBM Type 1 cable
