Shielding forms commonly used in shielded twisted pair (STP) cabling.

Explanation:
Shielding in STP serves to block external electrical noise and reduce crosstalk by surrounding the conductor pairs with a conductive barrier. The two most common forms are a foil shield (a continuous metallic layer) and a braided shield (a woven metal mesh) around the pairs, and some cables use both for stronger protection. Describing the shielding as foil or braid around the pairs captures how STP is constructed and why it reduces interference. While foil shielding can be implemented as aluminum foil, and metal conduit surrounds the cable externally, the shield itself inside the cable is typically foil or braid (or both). STP unlike unshielded options relies on that metallic barrier to perform its function.
