Starting with the client-server model, this book attempts to integrate disparate topics of state-of-the-art telecommunications principles. Typically, data communications and telecommunications have been separated, but are linked here. Timing of computers and the problems of jitter are brought to bear, as is multiplexing and circuit- and packet-switching. Protocol architecture is discussed from a point of functions that then lend themselves to the “layering” concepts. Business and regulation issues, pertaining to the issues discussed, are included. The book integrates these concepts by illustrating how these disparate issues form the underpinnings of the World Wide Web.
