Shielded Twisted Pair Unshielded Twisted Pair
STP - Shielded Twisted Pair cable. UTP - Unshielded Twisted Pair cable.
STP is costlier in price than UTP. UTP is cheap in price compared with STP.
STP require grounding of cable. UTP requires no grounding of cable.
STP reduces electromagnetic interference more than UTP Electromagnetic interference is more in UTP
Low crosstalk in STP Crosstalk in UTP is more than STP
STP is fast compared with UTP UTP is slow compared to STP
