40 seconds advice from 13:00 was much needed !!

[@SunilKumar-yx6db]

Your explanation is awesome. Please upload notes.

[@imerence6290]

Your async explanation is slightly off. Code will still run in a single threaded manner all the time. The only difference is, when Task 1 has to wait to do something, task 2 can start. When the task 1 is done waiting, it can pause executing task 2 and continue task 1. Here, the waiting scenario could be anything like disk read write, database read write, or hitting a URL. Asynchronous mean concurrent and Multi Threading/Multi Processing means parallel.
