Sir, you have a very neat handwriting. Very easy to see and understand. Also your accent is clear to understand. Thankyou

[akshatpitale]

Sir your videos help very much to understand concepts easily. Thank you

[nayanjain]

Sir please make video on DMA 8237
Or give a brief what is the difference between 8257 and 8237

[Krish-uyxy]

It is very usefull to me to understand the DMA

[arnabchakraborty]

Sir how can we use DMA for Memory interfacing?

[mnada]

During HOLD active is the microprocessor executing anything ? or is it waiting the DMA finishing its task ?

[tapaskumarojha]

How data transfer is happening between io and memory in the diagram?
This part is not clear.

[deivaffgaming]

Sir pls post mpmc notes in your website

[kanzariyakrutik]

if you will teach something advance in it then it will more usefull

[chinmaymathur]

Content is extremely short and not very useful where is pin diagram, you didn't explained about 4 channels, functional block diagram and etc are missing. I don't know why you did this sir.
