Direct Memory Access - DMA - Simplified Explanation

[@manojprabakaran5769]

this is the best simplified version of DMA. No where else you can find such an explanation.

[@pabloseijo572]

I have an exam of this in 4 hours, you just saved me mate

[@anamikakumari9536]

Please don't use background music for educational videos, it's irritating.

[@manoranjanbiruli2789]

After reading this comment my whole focus shifted frm topic to background music

the explaination is soo good

[@suryateja99660]

thankyou very much sir, This vedio saved my life, of 5 hours.

[@garvsrivastava9397]

The way you simplified the DMA structure was perfect. Animation made things easier for us. But why have you stopped posting videos. Please keep posting more videos on OPERATING SYSTEM :-)

[@joinsomejoy5473]

If you have any doubt don't ask me.. 😂 nice one... Bohot videos dekhi lekin kisi ne ye nhi bola

[@moazzamajameel8619]

I never comments but your video too good real😍

[@parthpatel8633]

There is one small mistake in diagram -> Step No 2 is DMAC request Disk Controller. Diagram mistake:- Step 2 look like CPU request Disk Controller.

[@jeevagayu9530]

Cpu initialize disk.. And DMA requst done

[@samarthtandale9121]

Awesome Video Brother !!! Keep up videos like this, you are really underrated - and when you get famous, don't forget me as one of your earliest subscriber 😁

[@goncalosousa9691]

DMA never interact with CPU??? And when we want to interact with CPU wich one is faster polling or Interrupts?

[@JeetKRamnani]

perfect explaination buddy good work

If these type of explaination can get from the profs.. then there will be no less. marks or F grades...

[@srinevassrinevas2637]

Which addresses will present in the DMA which is set by the CPU

[@praveen.3783]

[@nurazmanbinjunaini9998]

you are MVP..thanks

[@subhasishaditya4802]

U made it interesting . Thank u!

0:28 start 0:59 - 1:09 DMA is an operation in which data is copied from one resource to another resource in a computer without involvement of CPU.

[@vishwamcheedalla3926]

Its my humble request make videos on coa subject sir

[@asimahmed4277]

very usefull one and easy to understand

[@jeevagayu9530]

Cpu waits till data transfer? Or perform other operation?

[@beatx2173]

🎉♥️🔥good explanation

[@sardsagai7114]

perfect teaching bro

[@thoshifkhan6816]

For doing all these operations will take only one clock cycle? Since it was taking 2 cycle!!!

[@Tamilss2510]

looking forward for more videos

[@karanb2067]

are disk controllers present in the motheboard or are they having a space in main memory?

[@AhamedKabeer-wn1jb]

Thanks man.

[@pawankalyanks]

Well explained dude✨✨

[@parpudinaresh6295]

Hello Bro, I have a doubt that is disk controller also an another device? I thought that buffers also included in the DMA itself and the data transfer done by DMAC only ! if the disk controller transfer the data then why we need DMA ? Thanks in Advance,

[@nitikshaparekh6246]

I also have a doubt isme starting mei bataya hai ki computer ya laptop mei se data external storage device mei transfer hota hai but in explanation CPU reads the data from the external device ye meri kuch samaz mei nhi aaya

[@petersonjr8015]

Great explanation. But I'm kinda confused with the definition, which states that DMA removes the CPU from the process of data movement, but apparently the CPU still has to continually send the "DMA request" signal to the disk controller. This shows there's still a lot of CPU involvement; why can't the subsequent "DMA request" signals be sent by the DMAC instead? I think it would be great to see how things will happen without DMA, so as to better appreciate how much of the work is actually offloaded from the CPU to the DMAC.

[@francescocarboni50]

Every type of I/O device has it's own controller. A controller "translates" I/O device signals to commands readeble by the OS. Every controller needs CPU to access needed data in the main memory. With the DMA mechanism, a device can directly access the main memory, without "asking" CPU. This mechanism is controlled by the DMA Controller and affects the interrupt signals system. Hope I helped :)
