Studying computer science is really the best way to understand computer networks from the inside out. The best computer scientists will have advanced knowledge about how the seven layers of a typical computer network operate in tandem - to keep data moving where it's supposed to go. A daily computer user who has not studied computer science will probably have very little understanding of how his or her computer network really operates. In a sense, technology has evolved to the point where it is completely mysterious, or magical, to millions of users. Of course, for computer whizzes in Silicon Valley or Tokyo, the language and behavior of computer systems is easy to understand, and it is used to make refinements and advancements that change the way we live our daily lives.
Most libraries will have textbooks on computer science; however, these textbooks may be somewhat obsolete. In general, books from bookstores will have more up-to-date information. If you're looking for cool books on computer systems, look for manuals and textbooks written this year or in the last year. That way, you'll get information that isn't from the computer "dark ages".
