Great book if you're a manager and you want to understand every 3rd word of what your tech geek is saying.Good book if you haven't the slightest idea what a network is. You'll still need a tech geek to set it up.Terrible book if you're a tech geek. Doesn't give any information about configuring networks or troubleshooting. Plus the hardware is changing so rapidly that I'm not sure a technical guide in a book would be of any real use. Even the hardware companies refer you to their websites for current information.A friend in the biz gave a copy to me. He probably thought it was a waste of space on his bookshelf...If you're just starting out, visit PracticallyNetworked on the web. It's free and much more up to date.
