Computer Networks

Computer Networks won't save one minute over the next year. It has no step-by-step procedures, no problem solving sections, and no butt-saving tricks. The only purpose it can serve at a downed site is as a shield against thrown objects from frustrated users. Normally, theoretical books like this one receive a quick skim and are promptly sent to my for-looks-only tome tomb. However, this isn't a normal theoretical book. It's fascinating. In fact, I read it not once but three times. Tanenbaum fills over 700 pages with everything I didn't know, or better still, only thought I knew about networks.
