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 👍🙏

[@devtest8078]

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

[@rolandovillcaarias5112]

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. :)

[@pablon3115]

Best comment ever.

[@gnosis8142]

I would use "codependent" or "interdependent" instead of "dependent".

Hi Deepak, Love you content, way of presentation and in-depth concept explanation. Was wondering if you have any repo created for all the code that you showcase as example in the sides. It would really help to grasp the concept even further. Keep up the good work.

Very good explanation

[@ankurtripathi9799]

this is AKA race condition in os we can use binary semaphore(mutex) to solve this problem which ensures that only one thread can run the piece of code at a time and block other threads in blocking queue.

[@ShivamKendre-fc3su]

great playlist

[@rajeshg3570]

Very nice explanation. I've a question here -- I'm just trying to understand how 'CompletableFeature' could be used to achieve concurrency ( i mean to say, in the context of inter leaving)

[@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

[@DefogTech]

Good point, thanks.. will note it for future videos

Excellent, do u know O’Reilly? If u can make a total series of multi-threading courses, I’m going to subscribe to it! U r teaching style is really amazing! Fantastic!

[@parmarkamlesh6493]

Can you create video for system design like geo location based staff management and some custom frameworks.

[@lipi6535]

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.

[@DefogTech]

Agree about concurrency is about structure. But all programming languages require explicit use of tools (locks, threads, coroutines,async-await etc) to make it happen. Even on single-core machine, a thread waiting for IO can be bounced out and other thread allocated for efficiency (which speedens up the program).

[@lipi6535]

@@DefogTech I totally agree with you on this. To create proper concurrent programs you need tools like mutex locks, routines, threads etc. All I am saying is that program in the first example is also of concurrency. The execution of it is an example of parallelism.

[@cepi24]

Pleaae make video about various concurrency models

[@opentech5972]

ty man

[@gosnooky]

People like to bag on Indian KZbinrs, but this guy knows his shit

[@abhishekgowlikar]

Hats off

[@raghavdave1]

Can the lock be called inside the 2 thread functions? Instead of defining them outside the functions?

[@cpsarathe]

If you can convince experienced professional (I am convinced :)) with your explanation I would suggest go for big and conduct professional training online or onsite.

[@publicindia1179]

Nice one 👍🏼!

[@DefogTech]

Thank you!

[@winwinindiamyindia9980]

In the given example of Parallelism all tasks are independent to each other , but what if they are depends on each other or if they are sharing some object... wouldn't it be similar to concurrency where threads couldn't be execute in parallel manner

[@abhishekmishra-ph1dz]
