Very well explained, thanks a lot for your continuous support. One beautiful thing I observed is, Arun explains with general practical examples when any new process/concept comes in the topic, and that will help us remember permanently. Especially In the previous RAC topics the Airport and receptionist example was amazing about how a Scan listener performs load balancing. We look forward to more like this as much as possible.
That's a minor point. You have a video called an ovrview on tea and you start talking about cups, perhaps he was lazy and used a coffee cup or maybe he's talking about sweet milk vs blackness but he hasn't started by discussing what tea is. Isn't he a guy with a phd?,
