CCNA Module 4: Physical Layer – Introduction to Networks (ITN)
This is the third module of a series of videos I will publish on the Cisco NetAcad (CCNA) Introduction to Networks Course (ITN version 7). In this lecture, we will be exploring the Physical Layer of the OSI model, which is responsible for the transmission and reception of raw bitstreams over a physical medium. It includes NICs, cables and networking devices. The course materials are provided by Cisco Systems and they are copyrighted to Cisco. This video is made under fair use for educational use.
