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.

Good job brother. Am from kenya Africa...i love the way you are explaining them from real understanding. Very nice teaching

[@CHEVI789]

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.

[@maleeha9482]

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!

[@Sebkarp0]

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.

[@amjadiqbal478]

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. ❤❤❤❤

[@Chunat]

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 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.

[@suryakamalnd9888]

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

[@elenavolkova3515]

Thanks a lot for this valuable material and high quality video performance!

[@gregmckinley5178]

logic values are either positive (logic 1 floating) or negative (logic 0 grounded) current. So when the logic state is 0, the circuit is actually going to ground allowing it to power a small load from the output

[@johnplump3760]

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

When you play games, the processor remembers its achievements, and uses its new features for other applications. One is the "luck". By choosing luxury cars in Need for Speed, you upgrade the MB luxury car, your luck will increase in just 3-4 steps, that can be noticed during gameplay. In Explorer, your search results will become more lucky. It seems to be, Strength, Dexterity, Magic, Vitality, Agility, Intelligence, Luck are processor functions, when upgraded, it is stored in the internal cache. Old computers didn't have an external cache, SX had a 1 kb cache not described.

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.

[@brendawilliams8062]

I got this but computers? Well, no

[@deang5622]

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.

[@timrogers2638]

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.

[@ivarorno]

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.
