My analogy after going through your video.

Parallelism is like cars running on 4 different roads and concurrency is when those roads meet at an intersection how to manage traffic without accident using traffic light.
Great video as always 👍🙏

Hi, what about this definitions, "Parallelism is about doing lot of independent things at once", and "Concurrency is about dealing with lot of dependent things at once", that is what I understood that according your explanation. :)

Possibly the best explanation of Concurrency & Parallelism I have ever listened to. Well done.

[remarofail]

For me, it is the best tutorial for explaining concurrency and parallelism

[SpiritualManish]

Awesome as usual, clear voice, simple explanation. Thank you :)

[mayurlohar]

I checked lot of other tutorials. But the way you explained the things comparing with similar options alongside really helped a lot. This reduces confusion and gives clarity. Thanks brother 😊

It really helped me clear the confusion between parallelism and concurrency.

One of the best-explained videos on concurrency, thanks!

[KarthikaReddyS]

Nice explanation, Just one suggestion it would be great if you could show the difference of both wrto definitions as a single slide it would be good to memorise. For example timestamps 1:32 & 6:51 can be shown next to each other in single slide to communicate the difference effectively

never seen such explanation anywhere..it cleared my all doubts

[nooruskhan]

This (playlist) is best video tutorial on modern multithreading concept, Thanks :)

[dwivedys]

Never seen a clearer explanation of this extremely tricky topic 🙏🙏🙏

My question is "which concept is used when we run the first program in a single-core machine?"
As per my understanding (someone correct me if I am wrong): Concurrency is the idea of structuring a program in such a way that it can achieve parallelism when multiple cores are available. It is not about synchronization between threads.
Parallelism is about execution and concurrency is about the structure. (Rob Pike).
So in that sense, the structure of a multi-threaded application in any modern programming language follows a concurrency pattern. And this can achieve parallelism when multiple cores are available.

Excellent! Easy to understand. Thanks for great video

[goodtime]

Clear core explanation is an outcome of you wonderful experience.
Thank you for making video.

[kunalrai]

You are simply amazing, I have really not seen such a clear explanation anywhere . God bless you dear brother.

[puneetmishra]

Thank you very much for making these concepts clear! This can definitely help many learners to continue or start learning these topics with a greater enthusiasm. Thanks again 👍🏻😊
