Precise and clear explanation. Great video Ron.
I accidentally stumbled upon your and couldn't believe how good your content is!!! thank you
I accidentally stumbled upon your channel today and couldn't believe how good your content is. Coincidentally I also love DIY electronics and programming so this video is just *chef's kiss*
Major props! Your articulation is fantastic! Keep it up!!!
brilliant truly remarkable someone with such a small following makes a video this incredible
Not sure how I found you but what a great explanation of the the microcontroller and external rom ram access. Thanks
Major Tom, is this you? Your English is surprisingly amazing 😊 By the way this English version made even more sense to me than the russian one - which already was the best I could find on the KZread
Incredible explanation ❤👏 Much respect!
I thought this was like 5 or 7 minutes long so i can use this as reference whenever i got any presentation assignment. Then i saw the 27 minutes.. 🤣🤣. Anyway, good job Ron! I just woke up and making my cereal yet rightaway i already got the right video for me watching while eating 😆
Love the way you explain things clearly.. keep the good work.. thank you
Accidently come across your Programme... & decided to continue as articulation fantastic. Thank you But have to listen again on data transaction.
What a great explanation!! Thank you.
Thank you very much! Your Seminars are Very helpful to mel! ,And I can understand your clear English speaking 👋
very INSIGHTFULL 4 a layman ...... not seen video about programming with electronics fundamentals with such CLARITY .... need to watch it several times 2 internalise the knowledge
Great video and graphics! Thank you for this very enlightening explanation. I think it would be great if you can for example extend this to explain how C64 works (all different chips, etc)
you are amazing, thank you so much man
Its best video about this what i see, so clear explanation, thank you
very helpful ! thanks for sharing !
Fantastic presentation on how the computer is working. Thank you very much for the knowledge sharing. it was very comprehensive and soooo easy to understand. 🙏🙏🙏🙏👍👍👍👍💐💐💐💐
Is it 65536 bits or bytes ?? I guess it shall be 65536 bits.

You are confused. Address bus is of 16 bits. Hence it can access 65536 memory location in the storage or memory device. Each location of the memory can store 1 byte of data, which means 65536 memory location can store 65536 bytes of data.

brother is really good, top quality content
brilliant explaination
Excellent
Great video, should have more views!
👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏 no need words
The amount info this video contianed 😮👌
Really helpfulllll, thanks
It was great understanding microprocessor sequence, please if you can make more vidoes with simulation follow by arrow in input and output will be great.
thanksss alottt
Hey What u think happen if I make some kind pcb which has multi socket for two i3 processor and if I cam run the cpu does that make it faster ? Or it could just take single instruction and feed them into both and they both solving the same calculations?
I would to know how input works and how interupt bus works
Where eas this video 25 years ago? Would have saved me tons of time. 😂😆
My Idiot brain can understand to this difficult lessons in myl life, oke thank you my bro for yours video.
Finally a video that my smooth dumb brain can understand! 😁😁
How much max data can be read from memory at a time?.

Depends on data bus. If it's an 8bit bus, then 1 byte can be read at a time.
Whoa! It's crazy that no one person on earth understands how a pc works! That's probably why AI is beyond our understanding now.
Accidentally came... cleared almost all doubts
Thank you. Very informative video.
Thank you sire
