Networking Essentials, Third Edition

Book Description

Thoroughly updated to reflect CompTIA’s Network+ N10-005 exam, Networking Essentials, Third Edition, is a practical, up-to-date, and hands-on guide to the basics of networking. Written from the viewpoint of a working network administrator, it requires absolutely no experience with either network concepts or day-to-day network management.

Networking Essentials, Third Edition, includes expanded coverage of cabling, a new introduction to IPv6, and new chapters on basic switch configuration and troubleshooting. Its wireless and security chapters now focus strictly on introductory material, and you will also find up-to-date introductions to twisted-pair and fiber optic cabling, TCP/IP protocols, Internet and LAN interconnections, and basic network problem identification and resolution. Clear goals are outlined for each chapter, and every concept is introduced in easy to understand language that explains how and why networking technologies are used. Each chapter is packed with real-world examples and practical exercises that reinforce all concepts and guide you through using them to configure, analyze, and fix networks.
