Free CompTIA Network+ Training: Load Balancer and Bandwidth Shaper
By Ed Liberman ⋅ February 21, 2010 ⋅ Post a comment
In this video, I’ll go over two networking devices that you’ll need to know about before taking your CompTIA Network+ certification exam. You’ll learn about the differences between load balancers and bandwidth shapers. Load balancers are generally used when there is more than one form of communication available. They help to divide communication evenly between [...]

Free CompTIA Network+ Training: CSU/DSU
By Ed Liberman ⋅ February 21, 2010 ⋅ One comment
In this CompTIA Network+ training video, I’ll go over what Channel Service Units (CSUs) and Data Service Units (DSUs) are, what they do, and why they are used. A CSU/DSU is a hardware device that converts data frames used on a LAN into data frames used on a WAN. Typically, a CSU/DSU will be used [...]
Free CompTIA Network+ Training: Basic DHCP Server and DNS Server
By Ed Liberman ⋅ February 21, 2010 ⋅ 2 comments
In this free CompTIA Network+ training video, I’ll define basic DHCP (Dynamic Host Configuration Protocol) servers and DNS (Domain Name System) servers. I’ll also explain where you might find a basic DHCP server and why they are described as “basic” DHCP servers rather than simply DHCP servers. Finally, I’ll explain what a DNS server is, [...]
