Actually, no. The braid definition works, but ribbon cable, which indeed has separate conductors, should not be confused with ribbon shaped single conductors like flat magnet wire or the ribbon bond wires used for MMICs and certain other RF devices. In other words, "ribbon" is a general shape. It is true that there are varieties of ribbon cable based on ribbon conductors, in addition to the ordinary stuff.
