The first edition is still relevant today. You'll find that alot of books are still quite valid, mainly because the majority of today's technology came from years ago. The 2nd edition really just expands upon the first, and is equally good, but if you want to save yourself some money for now reading the first edition is just fine. Kris, From: "Jim Rampley" <[EMAIL PROTECTED]> Subject: Radia Perlman's Interconnections I know I have read from several posters that Radia Perlman's Interconnections book is a great book. Are we talking about the first or 2nd edition or both? I found the first edition on a bookshelf at work, but it was copyrighted in 1992. Seems kinda old, but thumbing through the book most of the concepts still seem valid. Is this edition worth reading or should I skip it for the 2nd edition?
