This is fascinating. My brain always wants to know how things work completely, down to their most basic level. I still have a hard time wrapping my head around how you get from this simple logic to a modern computer program. It also blows my mind how fast it all happens. As I type this message there are thousands of electrical circuits and transistors doing thousands of cycles for every letter.
@@jonathanlarsen4177 Be careful with that. It tends to get things wrong often, but not blatantly, just subtle enough that you'd think it was right if you didnt know otherwise
I BARELY passed my electronics class in college. I was able to grasp the analog stuff, but the digital stuff...especially when we got into hexadecimal...was a complete mystery. I'm glad there are people like you who can make sense of this.
damn i missed teachers like you in my high school. I was too interested about these gates but no teacher explained me like you . Thank you and god bless you .
Great video. The last time I visited this subject was around 1980 when we were messing around with a Radio Shack TRS-80 when 144k floppies were huge memory. Now, in my mid-50s, I have time to revisit electronics. Thanks for your effort in making these videos.
I have worked on computers starting in '50s. I have not heard people discuss the basics for a very long time. When I saw you on you- Tube I had to watch. Boy! did this bring back memories. People can not emagine what it is like to restring a core memory. Keep it going. I love it!! John
Thanks so much! I was born in 1992 but i've always been fascinated by early stage computers/machine code/etc. My dad got his start in the 80s on a TRS-80 model 100 which he still has to this day and remembers how to write simple programs with. But even that's easier than having to actually fiddle with gates. Pretty amazing the stuff you guyshad to put up with back in the day so my generation could have visual coding languages and gaming engines. My thanks to you!
The best presentation ever ..Just amazing how you explain electronics making it easier to understand. Things that could have been otherwise very difficult to understand when my own University lecturer is presenting 😂😂thanks alot
thank you. it is always nice to brush up on these fundamentals. So, thank you. It would make much sense now to do a video about how registers and instruction sets (simple ones like a simple addition ) is implemented using these.
Nice video, it's amazing how hard it is to find videos that actually explain what is happening without referring to abstract circuit diagrams, which are useful but not entirely enlightening.
That was so cool ,I have searched about besic computer knowledge in internet for many times But I couldn't understand . Surprisingly your TH-cam channel gave me what I want. Your channel is awesome.
Excellent elementary presentation. I’m a computer architect and this is just what we need to get youngsters interested in the field. You covered the essentials beautifully.
Finally, the magical way of your explanation made me understand the way how the electrical signal works with transistors and the so-called logic gates' basic functions. Thanks a lot you could open my brain to pick the interest which was not possible with many teachers.
This is why I find computers so fascinating. The number of genius ideas and inventions are mind boggling. Some very simple ideas but incredibly difficult to wrap your mind around it.
What's difficult about binary? you only have 0 and 1. Then you have a few basic logic functions: AND, OR, NOT, XOR. Expand that to NAND and NOR where the behaviour is represented by truth tables. It's easy It gets a bit harder when thinking about the different types of flipflops. And a bit harder when it comes to finite state machines.
I'm not actually studying in the field of engineering or physical sciences yet I have immense curiosity to know how even the most mysterious technical device works. This video does real justice to explaining things that are oblivious to become obvious and satisfying.
FINALLY...maybe other videos chipped away at it in my brain but this was the most comprehensive talk to a four year old handhold I've watched and finally gave me the basic building blocks for understanding roughly what's going on in a computer. So many other tutorials leave a bunch of things unexplained which doesnt let the noob mind complete the concept. Thank you so much for making this! The simplicity of this is just remarkable and that this concept is the building blocks of making something like unreal engine has me feeling like yes, AGI is just around the corner.
It was just amazing! Please make more such videos. As students we seem to be working on a pile of abstraction. Your videos help a lottt to get the basics clear. Please build your channel on the spirit!
Hey, really great video as always. I got into CS a few months ago and this channel has been a godsend for learning about computer hardware components in a way that is intuitive and easy to follow along with. I read about logic gates and logic circuits a few weeks back, and one of the things that struck me was how apparently NOR & NAND gates are universal gates that can be used to construct all the other logic gates available. Perhaps for a future video, you could expand upon the stuff you talked about here by explaining how these more complicated gates work.
Thank you so much for explaining a densely subject in the easiest possible formats. You saved me a lot of time from going through many pages of reading. Yes, I would appreciate if you explained how to read or understand current vs voltage graph or hysteresis of capacity vs voltage or the physics of a single transistor(solid state memory) to the simplest circuit of transistors contains one transistor and capacitor. What's the difference between capacitors and transistors(their difference make up of the device). I am a chemist building the thin layer of a transistor and really want to understand beyond understanding the molecular make up of the thin film's chemistry or physics of it. Thank you so much!
I bet there wouldn't be any better video on very basic concept of logic gates switching circuitary. You nailed it man, you nailed it. A real master of your subject. ❤❤❤❤
Great job on this video, you have a knack for making these kinds of things easy to understand without overcomplicating things. Keep it up, I'd love to see your channel grow!
I would definitely be interested in a follow-up video on this topic! Thank you for the great explanation on how this works, it really helped me! Keep up the good work!😎
Ohhh boy came across your chaneel while searching for sRam abd DRam . What a great content now watching it all your vdos. Love you man for your hardwork
amazing brother, i loved the whole video and escpecially the part where you got into the physical reality of these logic gates which I strugged to find information about in my university textbooks the most. amazing
Crazy how people came up with this (computers). From physical hardware to software and how it all works. Lot that goes into it. Just like many other innovations. Fascinating. When this or other technological inventions did not exist, to conceptualize and invent it, is mind blowing.
This is a better simpler way for me as I do basic electronics, I know what the gates do, but explaining why they act this way using basic transistors is excellent for me.
Thank you so very much for sharing this video. I am studying for my ham radio extra license and this gate business is a little confusing for me but, you have explained it in a way that is much easier to see. Thank you so very much. Jan
I really liked this video. Glad you pointed the transistor arrangement. You really made a video that is precise and very informative. Thankyou so much.
I know you say you like to just keep it simple, but damn, I feel like I need an introductory video prior to THIS video lol. Will definitely have to watch again. Thanks.
Hey I honestly gotta tell you that I love LOVE your channel It is thee best for beginners who want to have a little knowledge n understanding on everything I use liek computers for example I totally live your tutorials and simple teaching concepts Thank you so much 😭😭✌🏼✌🏼
Hello, thank you for the video, i learned that everything in computers is done with logic gates. Can you make a detailed video on how things we see in daily life are done with logic gates? How do computers run exactly?
Thanks for your wonderful work, you are very good at explaining things and i really appreciate that you use your skills for helping the strangers on the internet, and i really hope you would explain how the CPU works and ROM i'll be very thankful for you. (Sorry for my English,it's not my first language)
I remember testing a computer. We had a bezzel that held about 10 sheets of 15 x 20 with the schematic on it. We started on page 1 at the top left and pur a scope on every test point. If a part did not work we replaces the diod or transister. The system was sesigned by math people. They knew nothing about a pulse being delayed going through a transister. We had to add in circuits to get everything in sync. If somthing did not function properly, we had to sit down with them and figure out the solution. Those were the days. The kids today have no idea what really goes on inside a computer. JP
Hello Sir. You are amazing. Could you please make more and more videos of computer science stuff like this, including some electronics. You are brilliant and God bless you.
As computer science student who just started out, with physics, chemistry, maths and computer science, I want to get as deep as possible.. Plz another video but with extreme detail and info about everything.. I'm here after veritasium made a video about computers.. The early transistors were glorified light bulbs.. A. K. A vacume tubes.. And before that was physical switches with magnetic stuff, that was attracted when a nearby coil was fed current, opening the circuit.. So I want to get deep into the chemistry side of things, the transistor, and the circuit side of things and stuff.. Plz
i was looking for a video on how computers actually work and found this,which i think shows the beginnings of how it operates...as you said at the end of the video,there is a lot more to it,which i would like to know about...
I’ve enjoyed this video on and gates and such. I’m interested in more info on this and binary if there is anything else to add to it. And if you have some on electronics topics? please do. Thanks again!
I was thinking of exactly that just a week ago. how the boolean logic represented inside of a computer and just got the video without searching for it 😂 thx
I don't know how computers are designed yet but I have designed a calculator. To make design easy counting devices maybe are the way to go. For example, counter 1 counts up or down. Counters 2 and 3 only count down. The answer is always in counter 1. When adding the first number is loaded into counter 1 the second is loaded into counter 2. Counter 1 counts up while counter 2 counts down. When counter 2 equals zero the sum is found in counter 1. For the difference both counters count down. Again the answer is found in counter 1 when counter 2 equals zero. For multiplication the first number is loaded into counter 1. But when the times key is pressed the number is transferred into counter 2. When the times key is released counter 1 is cleared (reset to zero). The second number is loaded into counter 3. The number in counter 3 is the number of times counter 2 will count down to zero while counter 1 is increased. The reloading of counter 2 is not difficult but I am going to stick to the counting description for now. Each time counter 2 counts down to zero counter 3 is decreased by one. When counter 3 equals zero the product is found in counter 1. Lastly for division the first number is loaded into counter 1. When the divide key is pressed the number is transferred to counter 3. When the divide key is released counter 1 is reset to zero.The second number is loaded into counter 2. Counter 1 is then used to count the number of times counter 2 can be subtracted from counter 3. The quotient is found in counter 1when counter 2 can longer be subtracted from counter 3. Sequencers made of AND Gates Or Gates NOT Gates and Buffers are used to cause the counters to count as described above. Write me at Mark Finn P.O. Box 5038 Sonora Ca 95370 for all the information needed to learn calculators and video game design free of charge. But don't expect financial gain to avoid being disappointed. I am pretty sure money is not that way for most of us.
