Summary

Ethernet Networking Clearly Explained provides an in-depth explanation of all the interrelated pieces that go into an Ethernet network. It emphasizes that making a choice in one aspect of the network design often constrains choices in other aspects. It also emphasizes current Ethernet technologies, including Gigabit Ethernet, and how these new technologies affect network design choices. In addition, readers will be exposed to issues related to maintaining and securing their networks. This book is intended for IS professionals responsible for designing and implementing an Ethernet at a single location (LANs, not WANs) and readers who may not have a networking background. * Readers will learn to design and implement Ethernet networks that include a variety of hardware and computer operating systems * Shows how emphasizing a choice in one aspect of a network's design often contstrains choices in other aspects
