Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but there’s one foundational invention that almost everything else relies upon: the transistor. Gokul J. Krishnan describes what a transistor is and how this small device enables all the amazing things computers can do.
Lesson by Gokul J. Krishna, animation by Augenblick Studios.
this showed what i studied in a year in three minutse
A year? At school? In university we covered that in the first month.
during freshman year this topic was so annoying
+DarkPrject i cant say it ...in university (whispering)
because they tell us alot of nothing good like equations and how they are made ,material etc....they go deep in the unneeded
+DarkPrject i think he was joking :/
Mohammed Sami Yeah we went there too, but we just scratched the surface of materials and exactly how to build which logic gate. my condolences that you had to sit through more than three hours of those two topics in particular.
As a person who is currently studying Analogue Electronic and Digital Electronics , your animation and information on how Transistors work is 10x better than what my college teaches us . Hope you could expand more into this topic !
Indeed!
It's sad to see that an Engineer who builds these amazing technology makes less money than the Kardashians
Exactly I feel the same bro.
True dat
Lol
I think 80% of people in the world are fools leaving in to the society.
lol we still make good money just not billions
Every person living in the modern era deserves to watch this explanation. Well done!

***** u mad bro?
The most important thing i learned from this video is some transistors are friendly and wave to you when viewed under a microscope.
This is really interesting. Ted-Ed, can you make a video on how computers generate random numbers? A lot of software and games use random number generators nowadays. Are those numbers REALLY random? And if not, is there a way for a computer to generate TRULY random numbers? (without using internal clocks.)
every second would be much too slow, its more often, but jeha thats what they do. if you want it more random use something that can detect cosmic noise, this is unpredictable for us at the moment and i think it will be for very long time...
no, they're not. Computers are deterministic (they will always give the same results for an identical set of inputs), which is why the clock is commonly used as a seed to generate pseudorandom numbers, but it's still deterministic. There have been several approaches to generate 'truly' random numbers using atmospherical and thermal noise observed from earth, but that's the thing, you would need something external to the computer to create 'randomness'.
That has always made me think: the world operates by physic laws, for every action there is a reaction and it can be explained with mathematics, so, in a way, there is no randomness in the universe. If you, hypothetically, were able to take in account ALL of the world's 'variables', and knew ALL of the laws of physics (if that is even possible), you could in fact predict the future, it seems. That speaks in favor of a 'destiny', everything that happens is the only thing that could happen. Just a thought.
+Robin Maurya there is a way to generate truly random numbers using radioactive decay, but obviously you cant use it in typical PC, but maybe there is a new clever way of doint it that we dont know.
Quantum effects are random. A quantum computer is the only machine that can generate a 'truly random' bit stream. Having said that, pseudorandom generators can suffice for all practical applications.

Holy cow, amazing!! This system is so complex and interconnected. How did people even begin to think up a system like this? It's all so beyond me!
Little by little. It's not that complicated if you think that everything that is super complex is in fact just simple operations. A TON of them but still just simple operations.
From the bottom up, layers upon layers are built, hiding the complexity of the hardware or the software below and providing more and more powerful instructions.
I've had transistors explained to me so many times but i could never quite understand, which is embarrassing because i've been working with electronics for years.
Your explanation of vacuum tubes tho, with the grid, finally made it all make sense. I'd never known how vacuum tubes worked before. It was the missing link, now i finally get it!
Thankyou so much.
트랜지스터의 쓰임과 트랜지스터가의 원리, 또 트랜지스터가 만들어지기까지의 트랜지스터의 발전에 대하여 배워보는 의미있는 시간이 되었습니다. 감사합니다. 언제나 응원합니다.
I feel like I get it but I know I don't
I'm on the same boat. The video was literally in like another language.
Myrrh
same here
Watch Crash Course Computer Science's first few videos, they explains transistors and logical circuits in more detail
Me too
You should watch crash course computer science. It’s mainly for kids but still...
This video is so beautiful that I almost cried. Thank you and bless your heart.
That was awesome.. I never fully understood computers, mostly because people just say its just switches and never went into detail.
Check out this awesome video about CPU if you are interested in this topic /watch?v=cNN_tTXABUA
Are you interested? I a few days ago came across a great series of videos (its quite long) which explains how these things internally work and it is just brilliant, better than anything I've ever watched related to the topic.
+Chitraansh Popli. Bring it on
This video didn't go into any detail on how any of the logic operations work. The example they used with the adder and subtractor circuit didn't even tell what gates and their purpose was.
In the Adder circuit, for example, it makes SO much more sense if you know what an AND and XOR gate is, and what transistor circuit it is made of. Then you can truly see the beauty and simplicity that computers are comprised of.
+joel13598 and you might want to set the speed of the video to 1.25 or 1.5 :p
This was beautifully explained. Thank you.
Please make more about this topic, I'm now more hooked into learning the basics of working machines: namely computers.
4:53 a computer using a calculator. ASTONISHING!
PLEASE MAKE MORE VIDEOS LIKE THIS , about computers , networking, storage , etc. You guys are awesome!!!!!
This was far more thorough than I expected. Well done.
This was awesome. I want to thank the animator for the wonderful graphics and animation
I could not have even imagined that such an amazing videos can exist.
"what a time to be alive"
Especially when you have this video,yes
Hi I like the video
Where can I found out more about 1:15 ? Thank you
Search for Basics Computer architectures
Visit crash course
Look up Ben Eater’s videos on CZcams about logic gates.
The most easy-to-understand video about transistor I found on CZcams
This was a fantastic presentation. Thank you so much for creating it !
You've done a great job. I'd been looking for this precious video thanks for giving us.
Possibly the best video I have seen on youtube.
I remember discussing the old names and uses old computers in 3rd grade, takes me back so much
This was the first video iv'e seen that actually explains how computers work from the ground up and in a way I can actually understand.
most videos skip alot of the important detail that you included.
This video covers everything in a perfect way. Nice work 😊
Thanks a lot for explaining.
Thank you very much TED from morocco(المغرب) 👍
Great simplified video.
Wow! Computers have become so advanced. It's amazing what people have developed.
Magnificent explanation. Thank you.
Videos like these give you a very very very vague understanding.
For the love of god do not stop with the technology videos!
Really help to gel a few learning points. Thanks
treat to watch all the best for future
even though i had known nearly everything it was very interesting to watch, thanks for the amazing video!
Thank you for such a great video!
this is why i find computing so fascinating
Thanks a lot guys
Amazing. Such a small small thing making technology possible.
I wish this video was made an year ago. It would've helped me understand everything so much more clear than my prof.
Amazing animation this time!
Finally understood it! :)
컴퓨터와 트렌지스터의 작동 원리를 알고 나니, 컴퓨터가 수행하는 작업들이 한층 더 대단해 보입니다. 일상생활에서 쓰이는 물건들의 원리를 배우는 것은 참 재미있습니다. 유익한 영상 감사합니다.
This was much needed! thanks :) my exam's next week
I loved this video so much!
Very insightful.
Very well-explained.
I like how the transistors are moving characters from the system. I guess you could compare it that way.
Interesting and well explained. Keep the good work!
I enjoyed it a lot - thank you .
Very good explanation !
Just simply amazing......
I've never seen so concise and comprehensive lesson. Loved it. Keep this work up!
That was nice and easy to understand, thank you :)
What a nice video! All my 2 months research in a 5 min video :)
Thanks, for information
Once Again An Amazing Explanation..!! 😁
Finally another animation. Am 35 years. But dude your animation can catch attention
Really good one!
Nice video shot, thanks for sharing it with us, well done :)
Please tell me me more about computers! These videos are awesome
Amazing how intelligent we are.
Amazing how I get to grasp an idea, yet have no idea how would it be implemented ... I mean some people do miracles.
Yeah,I know right and plenty of still beat up our self with
words saying that we are not good enough,not smart enough
and that we will never be this and that but look at insects or
observe them (maybe ants)they join together to float in water and Use fungi
to help them break down food and have the ability to carryout incredible
incredible function like sight and they even make incredible decisions
and ones which are logical and that also say plenty about us we are
amazing look at the development of StEm for instance what we humans
has done is Incredible and we are all special.And everything we try
to understand have a simple way of being understood why because
our brains we say that this is hard and so on and that we are
not intelligent enough are say we will never be the next einstein or
terence tao but when say that we are only lying to our self because
we have plenty of potential but waste it.
Actually look how intelligent very few people are, and how dumb the rest are. They use the technology, but in the main would never even consider how they work.
***** But really the people who invented all of these amazing things aren't that different than everybody else. They just used their time and energy towards different goals.
Speak for yourself!
superb
Amaaazing! Can you make a video about how we got from simple calculations to complex graphics? Or how a touch screen works?
You are amazing!!!
Amazing sir 😊
Simply Awesome.....!!! 🙂
👍👍👍👍👍
beautifully explained TQ so much!!! :)
Very interesting! I love to see videos on how tech works, because for most electronics I have no idea.. 😅
Blows my mind how smart and dedicated people are. I just know how to do left and right click....
You explained it better than my instructors at Aviation Electronics Technician school while I was in the Navy.
Well I mean it is the Navy after all
these videos are too good..👌
takes me back to high school physics.. although i've all but forgotten this stuff..
Why do we call computer glitches "bugs?"
Back when computers used those vacuums, bugs would get sucked into them and they would stop working. Literally a bug.
i thiink it is where they coined the term
thanks for letting me know
Bugs got stuck in relays, not vacuum tubes though. It wouldn't be much of a vacuum tube if a bug could get into it.
According to this article, both of you wrong: curiosity.com/topics/why-do-we-call-computer-glitches-bugs-curiosity/
It comes from Edison's personal notes about his work.
Because bugs are annoying
awesome work dude :D
I love this channel sooooooooooooooooooooooooooolllloll much
Love to see how you tackle transistor theory.
awesome
Interesting...Computers never fail to amaze me....
marvelous
Learn lot of thanks
Brilliant
Awesome
brilliant
you guys are helping me so much in school
this is so cool.
What makes computers tick?
Broken components. You shouldn't be hearing ticks from your computer.
I put a baseball card on my GPU fan so now it sounds like a motorcycle
LMAO
Dad jokes
Hahah
Those vedios are great and helpful
I learned more from this than my three months at computer science. Yes, I have concentration issues
The transistors used in microchips are not bipolar transistors (with emitter, base and collector) but field effect transistors, which work somewhat differently.
/nitpicking off
like=true;
Hehe. True. For FETs, watch the Veritasium video on the same topic. The fundamentals are mostly the same but instead of a base being directly connected, it's just inducing a field.
Actually, most, nowadays, are FETs. :P
*The last words of this guy was amazing*
Great video. It is based on very real terminology. I often find videos that are too simplistic for the topic, this is not one of them even though it might seem like it.
Finally, clarification!
So cool
cool xplanation
Thanks
