Personal Communications Networks Permit person-to-person rather than location-to-location Each person will have his or her own personal phone number associated with a lightweight telephone that he or she carries around. People will not only transmit telephone conversations but also computer-based information, voice mail, electronic messaging, call screening, and other personal from anywhere. They will unlock levels of freedom we dont yet know, and they will be important for special events, such as political conventions and sporting events. as well as for emergencies. such as those caused by natural disasters

Procedure-Based Vs, Goal-Based Information Activities Procedure-Based activities Tend to consist of high volumes of transaction in which each has relatively low cost or value Are based on well-defined procedures (or algorithms)where the outputs are well-defined too Are based on the handling of data Goal-Based activities Tend to handle fewer transactions of higher value or cost Are based on ill-defined processes(or heuristics)and the outputs are less defined as well Tend to focus on defining the problems and the end results or goals with effectiveness stressed in achieving them Are based on the handling of concepts
