A First Course to Network Coding/How to Use this Book
As readers may already noticed, there are one or two sentences under each chapter's title. It briefly summarize the content of said chapter, so readers have a general idea of what they are getting into when click in.
The background section, as the name indicates, is a supplementary section for look-ups. There's no need to finish the section before entering the main body of this textbook. Rather, when you get stuck on a new term or find a concept blurry in memory, then open this chapter and look up for a definition, example or explanation. An alternative way is to seek explanation from Wikipedia, the free encyclopedia. The articles will be longer, sure, but more elaborate and rigorous due to mass review and edition.
