Profinet is 'one' of the several Industrial Ethernet protocols in the market. And one of the most popular/important one. Other ones are EtherCat, sercos, Modbus TCP, EthernetIP
Dear Ashwin, To make a long answer short: PROFINET is standard Ethernet reloaded for industrial purposes. You know and probably use Ethernet on a daily basis (at work, at home,… - e.g. when you watched this clip on RU-vid). PROFINET uses the same Ethernet as offices and IT departments, but you could say it is a potent and more reliable type of Ethernet. Its capabilities have been enhanced to meet the far tougher conditions encountered in industrial applications. Lost data packages while loading a website for example are nothing more than ‘a little inconvenient’, imagine a robot not moving properly, trying to pick up a component where it isn’t, or screwing something on in the wrong place. A lost data package in industrial automation could mean: you’re screwed.

Hello JK J, this is a very broad question. A lot of technical questions are answered at PROFINET University: profinetuniversity.com/industrial-ethernet/why-ethernet/ ("Why Ethernet?" or other articles like this one on the difference between PROFIBUS and PROFINET: us.profinet.com/the-difference-between-profibus-and-profinet/ )
In the network stack animation at 2:53 the IP and TCP/UDP are switched, aren't they? IP comes on top of Ethernet, then come TCP/UDP and above HTTP, SNMP, and so on.
Yes, you are correct, it appears this was swapped in the animation. TCP/UDP should be layer 4, IP layer 3. We will try to edit the video to put a comment on that section as well. Thanks for your attention to detail. :)
