scalability
     
        how well a solution to some problem will work when the size of
        the problem increases.
     
        for example, a central server of some kind with ten
        clients may perform adequately but with a thousand clients
        it might fail to meet response time requirements.  in this
        case, the average response time probably scales linearly with
        the number of clients, we say it has a complexity of on
        "order n" but there are problems with other complexities.
        e.g. if we want n nodes in a network to be able to communicate
        with each other, we could connect each one to a central
        exchange, requiring on wires or we could provide a direct
        connection between each pair, requiring on^2 wires the
        exact number or formula is not usually so important as the
        highest power of n involved.
