Business Data Communications

< >

This new textbook is designed for a one-semester undergraduate course in Business Data Communications for Information Systems students. Accordingly, it focuses on providing working knowledge of the data communications concepts and technologies that most students are likely to encounter after graduation instead of trying to cover every possible topic and technology in this vast field.

The author presents the minimal set of technologies that are absolutely necessary to enable computer networking in organizations -- including Ethernet, TCP/IS, ARP, NAT, DNS, DHCP, routing, subnetting and security – and focuses on showing what each of the technologies does, why each is necessary, and how each one works

Students will find this book uniquely engaging with hands-on exercises and two cases in every chapter to help them use and understand the networking concepts covered.
