The Complete Network Upgrade & Maintenance Guide [With Includes the Entire Text of the Book, Tools...]

The book covers about every networking related topic with enough theoretical and practicle depth to really understand what's going on.Some topics described are a little outdated but before a person can understand what's going on with today standards it should understand previous technologies. It's the only book i know that covers about every protocol used for the various OSI layers (from application standard to the cabling part) without getting too technical on the bit's and bytes level.I don't really understand why they choose the title "The Complete Network Upgrade & Maintenance Guide" since the book is more a global networking tutorial.A good, huge book i recommend to everybody that wants to learn about all concepts used with LAN/WAN (inter)networking.
