Very very very very clear explanation. Im saying this after referring to many youTube channels, many articles and many chat GTP responses. You gave me a better understanding about this concept. Thank you so much for your time, i know this would have taken lot of efforts, like creating the PPT's, scripting, fetching sensible and easy examples. Kudos to your work & keep the good work going

THANKS !
