Groups establish electronic mailing lists shey can share information mon interest. Professional colleagues exchange business correspondence electronically, and relatives exchange personal greetings.
Unfortunately, work technologies are designed for a specific purpose. Each enterprise chooses hardware technology appropriate for munication needs and budget. More important, it is impossible to engineer a work from a work technology because no work suffices for all uses. Som groups need high-works to puters in a single building. Low-cos technologies that fill the need cannot span large geographic distances. Other groups settle for a slower work that connects machines thousands of miles apart.
For over two decades, a new technology has evolved that makes it possible to in terconnect many disparate works and make them function as a coordinate unit. The technology, called working, modates multiple, diverse underlying hardware technologies by providing a way to inter
