[Understanding with pictures] The most intuitive understanding of the concepts of sync and async

Understanding the concepts of sync and async intuitively "with pictures"

Understand the concepts below in one glance with intuitive illustrations and explanations :)

1) The concept of sync/async
2) The concept of serial/concurrent
3) Why do we need the concept of concurrency programming?

I initially studied synchronous and asynchronous concepts using various examples to understand them, but I ended up becoming even more confused. Some parts were a bit tricky for non-majors to grasp at first... So, I created a diagram to help them understand intuitively and directly .

I think you'll understand how threads work more accurately and quickly if you look at a diagram. I'll try to explain it to you in a snap. ^^

(I couldn't edit the video for a while, so I uploaded it all in one take... Now that I look at it again... the breathing and speech stammering were really bad... I edited the video and re-uploaded it... As of October 6, 2020)

And, if you want to know more about the concept of Blocking/Non-Blocking, which is divided into more detailed concepts of synchronous/asynchronous, you can check it out in the news . ^^
(Since this concept may or may not exist depending on the language, you may want to check whether the language in question handles the concept of Blocking/Non-Blocking.)
