    1.    Unshielded twisted pair (UTP)
    2.    Shielded twisted pair (STP), which contains each pair of wires within an aluminium foil shield for further isolation.

    The basic difference between UTP and STP is UTP (Unshielded twisted pair) is a cable with wires that are twisted together to reduce noise and crosstalk. 

    On the contrary, STP (Shielded twisted pair) is a twisted pair cable confined in foil or mesh shield that guards the cable against electromagnetic interference.
