Answer» THERE ARE SOME TYPE OF CABLES- Shielded - (A) Twisted Pair (B) Multicore These cables are individually shielded, twisted pairs, used where the effects of crosstalk between cables must be minimized. Overall- data cables such as printer and control. Co-Axial - Co-ail cable is constructed of an outer insulated sheath with a shield of braided copper and in other cases is supplemented with a foil shield, over an insulator and a single core conductor that is concentric to the whole cable. Used where high bandwidth is required E.G Video , Digital signals Composite Multi core - A combination of shielded twisted pair and co-axial cables used particularly for large video cameras. A combination of shielded twisted pair and unshielded cables used for valve microphones.
