[@bengalibabu2435]

Sirji you are from a different planet. Awesome master piece.

[@VitaminCode]

Kya kehna chahta hai bhai 😂

[@SushrutKanetkar]

One of the best teachers I ever came across ! Thank you sir, you are amazing

[@hocky-ham324-zg8zc]

Using your definition at around 17:15, threads are contained in the same process as the main thread, and therefore are run on the same core. I think the overall explanation was good but in order for multiple tasks to occur on different cores, you need separate processes, not threads. Threads are also context switching, but the specifics of when to join the threads, etc. is done manually whereas async/await is done for you by the language.

[@rahulk2573]

I have a doubt that even if multiple threads are running on a same core through thread interleaving then it will concurrent programming and not parallel programming right? So is multi-threading not always parallel programming?

[@hocky-ham324-zg8zc]

​@@rahulk2573 yes, multi-threading is not always done in parallel. I believe if you have a multicore CPU, most OS' schedulers are able to correctly dispatch different threads to different cores. For CPUs with 1 core, they are still able to perform tasks concurrently via thread interleaving like you correctly pointed out.

[@rubyc7771]

Thanks for teaching like we're dummies. I can't express how much I appreciate your teaching style.

[@dorinpopa6962]

The best explanation of those concepts I have found on KZbin! 10/10!

[@aasurjya]

Great One, helped me building parallel core app in unity.

[@heezukaa8803]

One of the best tutorial i have ever found thank you so much hope you will upload more updates video about c#.

[@abidzahid2974]

Explained very well now I must say I am theoretically clear on concurrency and parallism

[@publicfare8939]

the explanation is so detail and easy to understand, thanks for your hardwork

[@antonyspiano2403]

Great job, I searched more than 20 videos for sure , to get a confident view on this.. you did it . Great job!!! Thank you!

[@rishabhmalhotra6474]

what an amazing video! great work and very glad to be able to understand these concepts as I have always somewhat struggled with these

[@RajuPatil-w2u]

Very well explained. Thank You Shiv

[@questpondvideos]

Thank You :)

[@tonybapuji5956]

Excellent tutorial with fundamental points clearly and concisely explained. Thank you so much!

[@danielvisan3405]

Thank you! Very well explained!

[@iam_ashishmishra]

Really Impressive... Thank you for making me clear about these concepts.

[@deltaphilip8611]

This has cleared up a lot of confusion for me.

[@zeenatmalik2816]

This is the best lecture on these topics 👍

[@imsraone]

Last picture was just awesome and make really sense :)

[@alshifamedicine]

Nice Explanation At 11:44 if instead of placing debugger on LINE17 place it at LINE13 and debug through code and observe the threads, see multiple threads as in case of parallelism. It appears async await use multiple threading in background but if its using multiple threads then why they need context switching?

[@gipbwok2008]

Good explanation. I think at 14:50 the word is "undeterministic".

[@VIjayKumartheh2o]

So I have question after looking into this video. Is Async & Await coming under concurrency? That's what I understood after looking at the Threads in debug mode.

[@ashutoshmishra2170]

I am big fan of your teaching 💕

[@johnnguyen1655]

I love those explanations. Thanks for your hard work!

[@vineetchaudhary7082]

I am a big fan of you sir. What a knowledge you have sir. Thanks a lot for such tutorials.

[@PankajKumar-tb5up]

Last images summarizes the whole lecture :)

[@successquotes-ts3dw]

Your are really producing good content sir

[@aktchungrabanio6467]

Wonderful explanation. Just a small correction: Instead of determistic, it should be deterministic. Other than that, excellent content.

[@TarunKomma]

To the point with lucid explanation ... hats off sir ji

[@ghanshamkashyup6235]

Very nice explaination ur video better than udmey videos

[@JagadishMori]

Very helpful and easily explained, thanks again

[@shashidev7941]

Thank you for this wonderful Tutorial.

[@scubagrant6045]

Great job. Very clear.

[@RameezTV]

Hi, when you said that threads were not created, because you didn't want to run parallely, but threads can run concurrently as well, right?

[@vrajeshbadgujar]

You are a Gem. Thanks!

[@epuriraghavendra3847]

Such a great explanation. Thank you sir.

[@abhi1779]

I have never found anyone who can explain better then Shiv Prasad Koirala Sir

[@vaishalidube4312]

Beautiful explanation!!

[@Dharmeshpatel-to2nd]

Very nicely explained :)

[@mferreira1231]

Superb explanation!

[@slobodantajisic2762]

Since one core can have multiple threads, is performing different tasks on different threads of the same core parallelism?

[@saikiranbhr]

Hi, As mentioned if async and await doesn't use threads then i have a doubt, I have created 2 async methods which are having some 20secs of code (as an example task.delay(20seconds)) and i have called them one after the other. If async concept doesn't use threads and if it only uses context switch then i think in order to run my code and show me the result it shoud take 40seconds ideally. But when i tried, it is taking only 20sec and gives me correct and expected output. Could you please clarify the doubt and do correct me if i am missing anything. Thanks in advance.

[@KanhaiyaKumar-rn6zg]

you are right async and await are not just context switching, It is about multi theading as well. if you want to know more detail about this o'really media has very good on async and await.

[@AB-cn5hb]

I hope I am not late. It's case of multithreading. He mentions in video about context swapping that only happens if no more multithread is available. For example, I have 2 core CPU and it has multithreading enabled. That means, I have generally speaking 4 core. So, when u use async, it is as it is working in different thread hence u see 20 sec. But suppose, I have 1 core CPU no multicore or multithreading. That's means all tasks has to perform in same thread. Hence, context swapping or time slicing. In this case, there is no benefit of using async other than responsive.

[@ahmed19924]

@@AB-cn5hb In simpler words, threads basically does work on the same 'Worker thread' but if we use 2 tasks then it will use two different 'worker thread'. Correct me if I'm wrong.

[@TheRetrospective]

Good video! One quick tip: 'deterministic' is correct spelling and not 'determistic'.

[@saikiranankam7617]

Super impressive. Excellent 🙏

[@Mr-Doctor-King]

You are the real MVP.

[@321zipzapzoom]

Nice explanation Sir

[@adamakkouche3297]

So as a consequence at the end of the computation, running our processes in series or concurrently is in terms of total time speed equivalent ? This is just a matter of perception.

[@rr9336093122]

was really clear and concise....thanks

[@shashankpandey1019]

You are the Real Rocks Sir 🙏🙏🙏

[@petrcipera8999]

Nicely explained!

[@hornybastard]

thanks. very useful

[@deependrajoshi199]

I want to understand here that you created 2 worker threads: NewMethod() and NewMethod1() and there is one main thread means total 3 but here in the debug there are 3 worker threads and one main thread means total 4 threads so why there is one extra worker thread created for?

[@programmadore9588]

very good explanation tho !!!

[@mihailomarcetic2516]

great video !!

[@adelhishem1]

Thank you for the video, really nice work.

[@tomarshabh2199]

superbbb!!!!!!!!

[@JourneywithNarasimha]

Thank you so much..... Thanks alot for sharing such a wonderful stuff

[@chimakurthiharitha513]

Shiv sir - Can I use concurrency and parallelism both at once as I need performance as well as usage both at a time🤔

[@unbekannt6111]

If u use parallelism u have the non blocking aspect included so.

[@nithinchandran7959]

You just cracked something i was worried about for many days..when are u going to release the second part?

[@questpondvideos]

Its here kzbin.info/www/bejne/fWTXq2yordmmbqc

[@vamsikumar_n]

sirji please make a video on Dependency inject in c#

[@sushilsuthar356]

Now i understood after so many articles and videos.

[@hosamhemaily4817]

really good

[@uribe2211]

Great!! thanks for sharing

[@danyaathiyaguthiyagu8175]

Async have .configuration(false or true) in their calling level . That is helpful for performance ?

[@izzyr9590]

IT developers. This is such a interesting name.

[@tnduc91]

great work mate, thank you!

[@ananyafrederick2524]

Beautiful!!!!!!

[@Gauravkumar-jm4ve]

Tx sir

[@joselucargarrido7511]

Nice

[@kumargaurav8619]

Nailed it!!!

[@programmadore9588]

Why does it show no threads running for me? 11:05

[@PI-Thoughts]

do not know, how many times i have watched

[@sachinbonde89]

👍👍

[@benyahiahassen4540]

the threads do not appear in my thread panel, does any one know why?

[@edipocdf]

Valeu!

[@questpondvideos]

@Edipo G Thank you for your contribution; it will encourage us to create more useful content. Happy learning....!

[@wew6438]

omg i can finally found an indian acent that i could understand

[@リンゴ酢-b8g]

as to his accent, of course it's indian

[@HarshaVardhan-dg7ii]

Imagine juggling with computers!!

[@AngryBerserk]

It looks like you are confusing concurency with asynchronism

[@questpondvideos]

Do put more explanation.

[@HateExisting-d3o]

not working

[@dibbyo456]

Excellent explanation. Thank you 🙏.

[@navneethegde5999]

Nice explanation!
