This text investigates the foundational principles and technical implementation of broadband data communications and local area network architectures. The authors, N. Squibb and R. G. Willson, provide a technical overview of the hardware, protocols, and signal transmission methods required to build and maintain interconnected computer systems. The book serves as a reference for understanding the transition from early networking standards to more robust broadband infrastructures.

The subject matter points to a dense, specialist text intended for engineers and students of computer networking during the late 1980s. The framing suggests a foundational, technical introduction to the hardware and logic that governed early local area network development.
