These free networking training videos provide you with comprehensive prep material for the CompTIA Network+ certification exam. Reinforce your knowledge of routers, media converters, switches, and network devices, all of which are necessary for the CompTIA Network+ certification exam. These materials will help you to understand the differences between load balancers and bandwith shapers, basic DHCP and DNS servers, firewalls and proxy servers, and so much more.
If you’re just getting started with networking or computer components, then you’ve got your work cut out for you. There’s a lot of equipment, system specs and best practices to keep track of, but they’re all important if you really want to work in IT. Quickly learn how to handle CPU fans and motherboards in these clips from our CompTIA A+ Training.
In this video presentation Ed Liberman, a 20 year IT veteran and Microsoft Certified Trainer, will provide you with a practical understanding of IP Addressing, working with Binary numbers, Internetworking and much more.
From our MTA Networking Fundamentals Training, Ed Liberman gives an overview of the hosts file on a Windows machine: where it’s located & how to find it, and how to alter it.
SWITCH Training by CCIE Joe Rinehart gets you ready for the CCNP exam, but takes the extra step to prepare you for real-world environments. This video explains the port variations among different switches.
You’ve read about IP addresses. You’ve explored the network settings on your computer before, but you may not know how all the piece work together—yet. Ed Liberman explains the TCP/IPv4 properties, what they do and how to change them on a Windows 7 machine.
“Show” and “debug” commands are common tools used to troubleshoot OSPF. This video from CCNP ROUTE Training features CCIE Joe Rinehart explaining the application of 10 common command tools for troubleshooting OSPF.
So, what is a command prompt? MTA Networking Fundamentals and Ed Liberman answer this question and many more about introductory networking concepts. This video shows how to use the command prompt window to view information.
In this video presentation Ed Liberman, a 20 year IT veteran and Microsoft Certified Trainer, will provide you with a practical understanding of the OSI model and the TCP/IP protocol suite — all in under 1 hour.
IPv4 addressing is quickly becoming something of the past. This video from CCNP ROUTE Training covers IPv6 routing and how it differs from (for the better) IPv4.
This network devices review concludes our CompTIA Network+ training series. These videos help to describe various network devices, functions, and appropriate times to use them.
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 [...]
Learn what a media converter is, how it works and how it differs from Channel Service Unit/Data Service Unit (CSU/DSU).
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 [...]
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, [...]
Continuing our free CompTIA Network+ training videos on the various network devices included in the exam, I’ll explain what a Wireless Access Point (WAP) is and how it is similar to, but different than a hub. Once you’ve finished this video, be sure to continue your CompTIA Network+ training by learning about other networking devices [...]
In this CompTIA Network+ Training video, I’ll explain what firewalls and proxy servers are and how they work. You’ll learn about their core functions and how they are different from one another. I’ll show you how firewalls control what data is allowed in or out of a network to protect private networks from external intrusion. [...]
In this CompTIA Network+ training video, I’ll go over some of the more advanced functions of switches. I’ll explain each function and give examples of when said functions are generally used. You’ll learn about the following Advanced Switch Functions: Power over Ethernet (PoE, used to transfer electrical power along with data over standard twisted pair [...]
In this video, we’ll be continuing our CompTIA Network+ coverage on network devices. I’ll be going over the different types of switches available including Multilayer Switches and Content Switches. You’ll learn about how multilayer switches provide functionality at higher OSI (Open Systems Interconnection) layers and how content switches actually handle the information being transmitted by [...]
A router is used to connect multiple networks together using sophisticated routing tables, which can determine the best route to get information or data packets from one network to another. The most common types of routers are meant for home users and simply send router information such as web pages, email, and other data from [...]
In this CompTIA Network+ training video, we’ll go over two network devices, bridges and switches, which are used to create and control collision domains. As you’ll learn in the video above, bridges operate at the Data Link layer of the OSI (Open Systems Interconnection) model. They have simplistic routing tables (compared to routers) based on [...]
