The "U" stands for Unshielded, the "S" stands for Shielded. For home use and office use, UTP is fine. STP makes sense in "noisy" (electrical or magnetic) environments, such as factory floors with heavy machinery, clinics & hospitals with specific machinery, etc. See more details on the kind of protection the shielding offers here: https://en.wikipedia.org/wiki/Shielded_cable https://en.wikipedia.org/wiki/Shielded_cable
