Understanding Logic Gates

День тому

We take a look at the fundamentals of how computers work. We start with a look at logic gates, the basic building blocks of digital circuits. These gates include NOT, AND, OR, NAND, NOR, XOR, and XNOR.
0:00 Transistors
1:21 NOT
2:13 AND and OR
3:28 NAND and NOR
5:17 XOR and XNOR

Easily the best "basic" video on the topic. Other videos either go into too much detail and are complicated, or miss the mark of making it clear, visual and accessible. Thank you!!!

Thank you for actually taking the time to explain the negations like NAND, NOR, and especially XNOR, that last one I was struggling with and the others videos I saw skipped all three of them completely

@@arjay_2002 I disagree.. Logic gates are fundamental to programming/software. I wouldn't say it's "useless" per se. My first few programs were input/output from logic gates (countdown timer, elevator controls, simple calculator) and ultimately got me interested in learning programming languages. Buuuuttt I would agree if you just want to program in C# or Javascript, etc., would be better to just go straight for it.

And this guy is not just reading from a book like a robot he actually knows what he talks about and hence I can learn more naturally from you bro. Excellent work. Really thankful for the help that you are providing I am gonna now go ahead and check all the videos on your channel. Much love❤❤❤Thank you...

I learned all this back in 1964, when I went to my very first electronic switching School, number one ESS, electronic switching systems. In the Bell System. I used it, daily, until I retired after 36 years. I was systems qualified in, number one ESS, tsps, traffic service position systems, number for ESS, First All Digital electronic switching system, number five ESS, first All Digital fiber optic system. All these systems are used in the Bell System for communication, that's how you telephone systems work. Today is October 1st 2022.

The way you explained the XOR gate made it all click in my head. I'm trying to understand computers on a lower level by creating one in Minecraft, and this video just demystified the concept of XOR gates for me. Thank you so much, and I hope you decide to continue this series.

@gregdemko5732 5 місяців тому

by creating one in minecraft?? been a while since i played that game, what kinda updates have made that possible lol

@datboi1861 5 місяців тому

@@gregdemko5732 Redstone can be used the mimic the "low voltage" and "high voltage" states of electricity, so it's a suitable source of power for machines in Minecraft. You can then use a combination of levers/buttons and redstone blocks/torches/etc. to get the functionality of basic logic gates. And you can go on from there to build some really cool stuff. People have been creating redstonde computers in Minecraft for a while now. Look it up. Its really interesting to see.

Can you make a video or tell about how computers perform what they do by combining these logic gates? This is exactly what i would like to learn. Thank you in advance.

@nathanaelculver5308 Рік тому

Very concise, clear explanation. Because I’m a visual learner, the one thing I would like to see at the end would be a simple example of doing an actual calculation with logic gates, just to give a taste of logic gates in action. _Telling_ me they form the building blocks of computer computations is one thing. _Showing_ them in action is much more satisfying.

@epicfilms4life507 Рік тому

6:07, the way I see the XOR gate is that we are checking if the two bits are in an OR state AND in a NAND state (exactly what you see in the text, but it makes sense this way to me.). Look at the diagram, the AND gate is connected to an OR and a NAND gate (the AND followed by the NOT) SO we check if its in a NOT AND state, and it is also an OR state basically, which essentially ends up ruling out the AND situation and also the both off situation as it must be an OR, keeping the OR states only.

Interesting topic... wonder if quantum cpu's are based on the 3 logical gates combined all together where 1 an 0 are the same. Because this looks very familiar to that concept. As Nand is already used for memory storage devices and obviously have a higher performance rating than traditional one's, wonder if there is any connection or just coincidence after all they all rely on electronic and physics rules at their fundamentals the only difference isthe application field . Maybe a good followup for a future IT video ;)
