Learn about Networking (Ethernet/IP) with these videos

Recommended Posts

The user Ben Eater on YouTube makes excellent videos on how computers work at their basic level, how networking works, etc.  I love his series on building your own computer from scratch.  By scratch I don't mean by buying a power supply, motherboard, etc.  I mean from LOGIC GATES and physical wire.  I know what accumulators, program counters, and registers are (intimately!)  His videos showed how they actually work on the hardware level.  I knew what they did - now I know what they are.

This led me to his other videos, and a set he has on Networking.  His videos take you from the lowest levels of computer communications, all the way up to IP.  They are easy to follow as each video builds on the previous ones.  You are not going to be a network engineer when you are done with them , but they will give you some insight as to how everything fits together.  Some of the concepts are very technical but he does a good job of explaining them.  For example, one of the topics he goes into detail is about having an accurate clock at both the sender and receiver of information (data framing).  He then goes on to explain how clock and data signals are combined in something called 'Manchester Encoding'.  You'll NEVER EVER have to know how to 'Manchester Encode' ANYThING in your life, but seeing how it is done gives you the tools to understand how other encoding is done.

He is not going to teach you how to assign a static IP address, how to turn off adapters, or anything like that.  Instead, you will come away with the knowledge of WHY you need to set a particular address, or WHY a packet doesn't make it to your PixCon when you have 2 adapters active without routing metrics/tables, or why your ISP just shut down your connection because you were leaking E1.31 packets onto the internet.

I suggest setting aside approximately 2 hours and watching the entire 13 video series from start to finish in one sitting.  Remember that the idea is not to become a network expert, but to get a general understanding WHY things work the way they do.  Don't get hung up on the details, just learn the how the  parts all stack together.

This is the first video in the series.  The entire playlist is linked above.

I'm interested if anyone has watched these (or one) and what they thought...  Doing these things for a living means that I could be wrong in thinking he is explaining things in a down-to-earth, easy-to-understand manor.

Just my 2 cents 🤓

I watched all 13.  My question is how it relates to LOR networking of the LOR or E1.31 networks?  With my background I can make the basic jump from IP/TCP to LOR/E1.31 but I wonder how many others can make that jump.  The youtube vids were very technical, interesting and informative, well worth my time, but was hoping for just a little more insight into the technical way LOR handles networking.

Thanks for the reply! 

For me, understanding how E1.31 works starts with a foundation of understanding of how networking happens.   

E1.31 sits at the top of the osi model, and these videos build from the bottom.   It was my thought that a good foundation could help.  Knowing why a packet does what it does could help with why you can't configure your controller. 

Thanks for giving them a watch !

Just saw this thread and watched the 1st one {in your post above}, plan on watching all 13, but it's about time for me to hit the bed shortly.  But will definitely be giving these a watch.

Thanks for the link and info on these, I believe these will be well worth watching!

P.S. Got both links bookmarked for later watching!
