Course description

** this course is updated for current certification N10-008 with parts 1 through 7 starting at https://www.learnnowonline.com/course/npe** In this session we cover a lot of ground on cables, cables, and more cables. First there were the twisted pair cables that are most prevalent on today’s networks, then there was the history lesson on coaxial cables used in earlier implementations of Ethernet. And then you will see the various types of optical cables that exist, single mode and multi-mode fiber of various types and distances. We will see that in some cases you aren’t dealing with cables at all but instead the various wireless communication technologies. We'll end things up with an overview of the network devices that are required to connect nodes on the network.
