coaxial cable
     
         A kind of cable with a solid central conductor
        surrounded by insulator, in turn surrounded by a cylindrical
        shield woven from fine wires.  It is used to carry high
        frequency signals such as video or radio.  The shield is
        usually connected to electrical ground to reduce electrical
        interference.
