One of the best videos ive came across explaining cpu, moms, and rams
Major props! Your articulation is fantastic! Keep it up!!!
Incredible explanation ❤👏 Much respect!
What a great explanation!! Thank you.
Wow. This is better than any course I've taken. The visualizations are extremely helpful
I accidentally stumbled upon your and couldn't believe how good your content is!!! thank you
Precise and clear explanation. Great video Ron.
Thanks 👍
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 😆
Thank so much . I enjoyed your presentation.
Not sure how I found you but what a great explanation of the the microcontroller and external rom ram access. Thanks
Thank you very much! Your Seminars are Very helpful to mel! ,And I can understand your clear English speaking 👋
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*
Same case here me also
Accidently come across your Programme... & decided to continue as articulation fantastic. Thank you
But have to listen again on data transaction.
Your show makes me, as a keyboard specialist, continue to appreciate the technology of the microcomputer, like the one I use. 💙
brilliant explaination
Its best video about this what i see, so clear explanation, thank you
very helpful ! thanks for sharing !
Brother,This is the most impressive video I have seen that explains how computers function.
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
Xcellent presentation was able to understand most of it except how the cpu understands signals from input output and also the reset circuit and how it interacts with the cs port of ram
you are amazing, thank you so much man
brilliant truly remarkable someone with such a small following makes a video this incredible
brother is really good, top quality content
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 RUclips
that was damn understandable. Very good job there!
Great video, should have more views!
Great content! Keep it up!
Thank you. Very informative video.
Wonderful content 🎉
Crazy ! Using a computer ( android smart-phone ) to learn how a computer works.
Really helpfulllll, thanks
very awesome and amazing 👍
The amount info this video contianed 😮👌
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)
Very good !
This a great channel
Excellent
thx sir.😅
AMAZING
👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏 no need words
thanksss alottt
this is incrible😲
superb
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.
Love the way you explain things clearly.. keep the good work.. thank you
Нифига Том тут отжигает 😂
I like this picture 🖼️ 10:34
👍
one subscriber 👍
this video is fucking awsome, now I understand why cpus are called 8 bit or 32 bit etc. amazing, how fascinating the world of it is
I would to know how input works and how interupt bus works
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?
wow >> where have u been ?
Where does the frequency of the cpu and memory come in?
My universitys full "microcontroller and interfacing" course in this one video 🤝🙆
They need to add a dual read and write ✍️ with multiple SSD
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. 🙏🙏🙏🙏👍👍👍👍💐💐💐💐
Computer lover🗣️🧎 0:32
Finally a video that my smooth dumb brain can understand! 😁😁
Lmao smooth brain
hello but 32bits architectures means that the size of the bus is 32 bits 32 wires
Where eas this video 25 years ago? Would have saved me tons of time. 😂😆
What is data and bit in an computer
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.
Byte
Answer is "bytes".
In the video , example has 16 bits wide adress bus and 8 bits wide data bus system. 65536 x 8 bits (1 byte ) memory at one memory module.
*_The data center in Nagawara has imploded, suffering 6,000,000 casualties , due to a buffer in the amount of data required for fision maintanence._*
Is 65536 bits not bytes
My Idiot brain can understand to this difficult lessons in myl life, oke thank you my bro for yours video.
What do you mean the reset vector is at address 0? Is it not at 4GB - 16 bytes?
We are talking about 8 bit CPUs here. Both the i8080 and Z80 have reset pointing at address 0.
Perfect illustration of how it could work in an 8-bit microprocessor interacting with memory and indicator LEDs.
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.
please fix the audio, your ‘s’ is very sharp and makes the vid nearly unwatchable
Gotta take care of this, thanks.
@@RonMattino thanks a lot, it is a great vid even with the sharp ‘s’ es but it can become even greater
Thank you sire
Accidentally came... cleared almost all doubts
