ABSTRACT
High-speed local area network (LAN) and wide area network (WAN) media give people access to the information they need by connecting information devices through intelligent, mostly secure, and reliable networks. Regardless of differences in time, place, or type of computer system, high-speed LAN/ WAN hardware and software products link computers so people have access to information. This efficient exchange of information has led to cost savings, process efficiencies, and closer relationships with customers, enterprise partners, and employees. High-speed LAN/WAN planning solutions have become the networking foundation of thousands of enterprises, universities, utilities, and government agencies worldwide — and the focus of this book.
