[Understanding with pictures] The most intuitive understanding of the concepts of sync and async
This is a 19-minute lecture that will help you understand the concepts of synchronous and asynchronous programming very easily.
About the concept of additional Blocking/Non-Blocking
Hello! This is Alan.
I made a short lecture, but I don't know if it was helpful! However, many people left good reviews saying it was helpful, so I feel like it was a good idea to make the class. ^^
It's nothing else, other than the occasional synchronous and asynchronous concept,
What is the concept of Blocking/Non-Blocking ? These kinds of questions have been coming up.. If there is anyone who might be interested, I am leaving the content here in case it will be helpful.
I think it is a priority to first learn the synchronous/asynchronous concepts that I talked about in class. Since some languages do not use the Blocking/Non-Blocking concepts, I think you should first check if these concepts exist in the language you are studying. ^^
Yes, if you are using a language that uses the Blocking/Non-Blocking concept, I recommend that you refer to the content below.
▶︎ Blocking / Non-Blocking is an important concept in whether the called function returns immediately or not.
1) Blocking - does not return immediately (blocks work from being done)
2) Non-Blocking - returns immediately
▶︎ Synchronous/asynchronous : Whether the calling function or the called function (callback) cares about whether the task is completed
1) Motivation - the calling function cares about completing its work
2) Asynchronous - the called function (callback function) cares about the completion of the task.
(However, it is said that this concept of combining Blocking & Async is not used intentionally because it does not allow other tasks to be done anyway .)
And in languages where the concept of Blocking/Non-Blocking is not generally used, as I said in class,
It is convenient to think of synchronous as a concept combined with Blocking , and asynchronous as a concept combined with Non-Blocking .
And if there is any other material that someone else has written very well, I will also attach a link. ^^

Thank you. :)
