E-Book Overview
I highly recommend this book to anyone desiring to learn the basics about Cisco networking. This book has great visual illustration and easy to understand wording that a person can learn the terminologies and their functions. You will learn the OSI model and the way each layer communicate with each other. The technical aspect of the book is a guideline to understanding networking infrastructure, network design, securing a network and many more function such as VPN.
