Query: Tries to teach everything but doesn't teach much

This book is supposed to teach you network design and admin, amongst other things including basic computer knowledge, in just 24 hours. If that is possible, all those network designers and administrators out there will be out of a job very soon.The only saving grace is that a bit of everything pertinent to networking is covered. For me, that's still insufficient reason to read the book.
