Hello all,

Five months ago, I posted this thread announcing a new (free) video series I am creating that will teach anyone the core of networking: How data moves through a network.

It was well received by this community, and I've since then continued the series and created four more videos discussing Switches and Routers and wanted to share them with this community.

• Network Devices - Part 1 - Hosts, Clients, Servers, IP Addresses, Networks
• Network Devices - Part 2 - Repeaters, Hubs, Switches, Routers
• OSI Model - Part 1 - Layer 1, Layer 2, Layer 3
• OSI Model - Part 2 - Layer 4, Layer 5/6/7, Encapsulation De-Encapsulation
• Everything Hosts do to speak to other Hosts on the Same network
• Everything Hosts do to speak to other Hosts on the Foreign networks
• Everything Switches do to facilitate communication - Part 1
• Everything Switches do - Part 2 - Unicast Flooding, VLANs, Multiple Switches
• Everything Routers do - Part 1 - Routing Table and how it's Populated
• Everything Routers do - Part 2 - Using the Routing Table and ARP table to forward packets

Each video above is meticulously crafted to build upon the prior videos. At the end of the serious, you'll have a very firm understanding of everything involved to make packets move through a network.

A lot of you are already familiar with all this. But I'm sure you all know people that are wondering what "the networking folks" are doing all day... this series is a perfect answer to that, and will give anyone else you might work with a run down on how Networking works.

Hope you enjoy the series. Any feedback is welcome (positive or negative).
