The content covers the basic knowledge and typical technologies of computer networks, and also involves practical parts. For people like me who are passionate about computer technology, it is simply a treasure book! The author Xu Lixin must be an experienced boss, and this book is the crystallization of his wisdom.

All in all, five-star praise!
