1 One does not attempt to capture everything in one's dissertation. 2  The dissertation is a technical work used to document and set forth proof of one's thesis. 3  It is intended for a technical audience, and it must be clear and complete, but not necessarily exhaustively comprehensive.
Twisted-pair cable. A twisted-pair cable is a cable made by intertwining two separate insulated wires. There are two twisted pair types: shielded and unshielded. A Shielded Twisted Pair (STP) has a fine wire mesh surrounding the wires to protect the transmission; an Unshielded Twisted Pair (UTP) do not.Shielded cable is used in older telephone networks, as well as network and data communications to reduce outside interference.

An early example of shielded twisted-pair is IBM STP-A, which was a two-pair 150 ohm S/FTP cable defined in 1985 by the IBM Cabling System specifications, and used with token ring or FDDI networks.ecause the shielding is made of metal, it may also serve as a ground. Usually a shielded twisted pair cable has a special grounding wire added called a drain wire which is electrically connected to the shield or screen.
