bandwidth
     
         The difference between the highest and lowest
        frequencies of a transmission channel (the width of its
        allocated band of frequencies).
     
        The term is often used erroneously to mean {data rate} or
        capacity - the amount of {data} that is, or can be, sent
        through a given communications circuit per second.
