Query: Technical Info, Laymen's Terms

I haven't read the entire book, but have used it as a reference. Its description of how a Token Ring network works is the most complete, yet clearest, I have ever seen. Anything I've looked up, I've understood by the time I've put the book down. The only problem is that, since it was copyrighted in 1992, some of the info is getting dated.
