Data Communications

With ready-to-use PC communications software, this book explains and illustrates the fundamental techniques of data communications and offers "Commkit" - a software package that is designed to allow readers to see how networking systems actually work. This book includes practical coverage of the function of synchronous and asynchronous communications, error detection and correction tools and techniques, strategies for using common-carrier telephone systems for computer communications, the three major multiplexing methods, network interconnection procedures and layered architecture construction. The "Commkit" software assists the reader by offering working simulations of modern software, error detection and LAN analyzers, and fully experimental models of a wide area network, token ring and UNIX socket interface.
