CompTIA NET+ Cert, Part 02 of 17: Media and Hardware

Course description

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.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes the user has some experience with computer hardware, software, and understands the concept of a computer network. The user should have viewed CompTIA NET+ Cert: Theory and Communications before taking this course.
