Hands-On Networking with Internet... | Buy

Acclaimed author Douglas E. Comer's book, "Hands-On Networking with Internet Technologies, " upholds the assertion that the best way to learn is by doing. Through laboratory experimentation, students and professionals gain a better understanding of how computer networks and Internet technologies operate in practice. Organized into sections that focus on the hardware and software platforms of different lab facilities, this book systematically constructs and augments a practical knowledge of networking. From single computer applications to advanced network systems engineering, a broad spectrum of hands-on experiments addresses a variety of difficulty levels, and guides the user to a deeper comprehension of the functionality and subtleties of networking in action.

Douglas E. Comer is a professor at Purdue University, where he develops and teaches courses in computer networking and internetworking
