CCNA Self-Study: Network Media (The Physical Layer)

Chapter Description

To determine what transmission media is right for particular networking enviornment you must consider organization's required throughput, cabling distance, noise resistance, security, flexibility and plans for growth.In this article Steve McQuerry highlights the concepts and procedures for assembling and cabling Cisco routers.
