CCNA Jumpstart

Use CCNA JumpStart to get up to speed on what you need to know before you begin Cisco certification training. This book provides a thorough grounding in the essentials of internetworking -- from the OSI model and TCP/IP stacks to routers, switches, bridges, and hubs. You'll learn what the components of internetworks are, how they communicate, and what contributes to performance (and what degrades it). Written by two Cisco Networking Academy trainers, this approachable book features end-of-chapter review questions and is great for both classroom use and self-study.
