Prepare to pass CompTIA's new Network+ Exam! This straightforward, no-nonsense guide to installing, configuring, and troubleshooting computer networks not only prepares readers to pass the certification exam, but serves to provide information on basic computer technology to the networking professional as well. Topics are thoughtfully organized in accordance with CompTIA's test objectives, taking readers through the seven layers of OSI so readers learn how information starts at one computer and ends up at another. From there, hands-on coverage of how networks are set up and configured is provided, which transports readers out of the realm of theory and into the "real world" of networking.
