We have discussed s e technological trends and some technologies and have attempted to forecast some of the implications of each to communications and computing. Some general conclusions hich cut across technologies an worth reemphasia ing in omens global context: We are on the verge of an era in which we will have significantly re bandwidth and interconnection flexibility than we have ever had. It is likely than there will be more, inhially at least, than we now know how to use to advantage. Similarly, we will have a greatly enhanced capability to distribute processing among a large number of data processing hosts. At present, however, we have no good criteria by which to determine when distributed processing makes good long-term economic sense; frequently it is difficult even to see it distributed processing is currently feasible a given application situation because of the complexities introduced by sharing data bases and application logic, for example.
