An electrical connection which allows two or more wires or lines to be connected together. Typically, all circuit cards receive the same information that is put on the Bus. Only the card the information is "addressed" to will use that data. This is convenient so that a circuit card may be plugged in "anywhere on the Bus." All computers and most telephone systems use buses of some type. Computer buses are typically open. Telephone system buses are typically closed.
