Detailed explanation-1: -Coaxial cable, or coax (pronounced /ˈkoʊ. æks/) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.
Detailed explanation-2: -These are typically known as coaxial cables (view image below). Braided (coaxial) cables have two conductors and contain a center conductor and an outer conductor separated by an insulated shield. They are generally less expensive and used for a number of different frequency transmissions.
Detailed explanation-3: -There are two main types of coaxial cables – ones with an impedance of 75 Ohm () and ones with an impedance of 50 Ohm. Cables with 75 Ohm are mostly used for video signals, while 50 Ohm cables tend to be used for data and wireless communications.
