For what it’s worth, there were computers before transistors. So really what transistors did for us was to make the computer a more practical tool by virtue of being much smaller, less power hungry, and far more reliable in operation (e.g. no burning out vacuum tubes left and right, no need to constantly tune or tweaks parts to keep it operating correctly). - electromechanical relays -> vacuum tubes -> transistor with a lot of interest rabbit holes like magnetic logic/

++ I always wondered, if they're really a switch, then who turns it on or off, turned out a quartz clock ticking at some billion times a sec (GHz) is ignored or taken into account by some already encoded transistors/memory in BIOS chip, if there is no initial memory/information then transistor would do nothing, as you don't have anything to control them... Manufacturers program a BIOS chip externally and then solder it in on the motherboard.

A Richard FeynmanIf quote comes to mind watching this: "If you cannot explain something in simple terms, you don't understand it. The best way to learn is to teach. The ultimate test of your knowledge is your ability to convey it to another. " I would say you pass that test, beautiful work.

@SergiuCosminViorel Ай бұрын

not very smart, as the understanding of things one man has, cannot be conditioned by the unwillingness of others to learn. in fact, a person understands more than can ever teach, therefore the fact that that person failed to teach, is not real measure of what that person knows. the real state of understanding is limited to the person only, has only sometimes to do with the teaching. Feynman just something that is not really smart. we can talk even more about understanding things, when we acknowledge knowledge is not only compared with some absolute refferencial, but it is also relative, meaning among people who know less, you don't need to know a lot, in order to know more than others. again, Feynman not so smart.

You can count binary on your fingers, using each of your digits as a binary digit, carrying to the next finger just as the flip boards at that timestamp. Expressing 4 this way is flipping the bird but you can do it in front of anybody comfortably if they're aware the context is counting to 4.

@Ramy_Ramz Жыл бұрын

That’s a 5 digit so every digit that’s 0 doesn’t get added and every 1 does. Reading it from right to left so it goes like 2, 4, 8, 16, 32.. and so on. Every digit gets multiple to the power of two starting from 1 (1^2) because we have 2 selections for every switch “on” and “off”. So 10101 would be 1+4+16=21

Cool video, I really love this kind of projects and yours look awesome. Just wanted to point out a transistor is very fast, but it's not even near the speed of light. They have a switching speed, which is defined by it's capacitance and it's shape (size) and it's measured in frequency. If you check the transistor datasheet you'll find the gate delay and it's probably going to have a formula. Also, the wire's in a circuit are not perfect conductors and they have resistance, which makes the electricity move at around 1/3 the speed of light. It's still pretty fast, but not speed of light fast.

My Clock, RAM and address register is pretty much identical to yours.
