CompTIA NET+ Cert, Part 06 of 17: LAN and WAN Infrastructure

In this course we’ll took a more detailed look at the various network devices that you will be involved with working as a network technician. We’ll start by analyzing the various types of switches as well as their cost and capabilities. Next in this session we’ll shift focus to look at WAN transmission and connectivity options that exist for today’s networks. We start by describing the various methods that organizations might tap into to provide connections to the internet as well as other offices. These included various styles of networks such as circuit switching networks used by DSL, ISDN, and T-Carriers, cell-switching networks used by ATM, and packet-switching networks used by Frame Relay and MPLS. We then discuss various options for connecting to the service provider providing access to those networks. We’ll finish by looking at the common concept of converged networks where we can maintain different types of traffic, such as voice, video, and data on the same underlying infrastructure.
