In many ways, our memories make us who we are, helping us remember our past, learn and retain skills, and plan for the future. And for the computers that often act as extensions of ourselves, memory plays much the same role. Kanawat Senanan explains how computer memory works.
Lesson by Kanawat Senanan, animation by TED-Ed.
The fact that humans managed to invent these things is insane
I swear if like 3000 of us were sent back to the stone age we all have trouble finding food to eat- let alone make a computer!

yup, deepens my appreciation and love for humanity

What I have learned from being a PC enthusiast for about 2 years:
Heat ruins everything
True
So true
yeet the heat
You don't need to be a pc enthusiast to know that
Oof
"Immortality is out of reach, for humans and computers alike."
That really hit me!
Yes but machines are not aware of their mortality.
@@marccolten9801 they will be soon
@@wisedude4506 Reminds me if Futurama.
Me too, it makes me really confused as to how should I behave.
Me too
Being a memory designer, i am shocked that this clip explained basics so easily, well done..
Teachers are worthless they manage to make everything impossible to learn
Haha yes
why are you here
Bruh...it would be so fun to create memories
@@architmishra0057💀
This was a lot more detailed than I expected it to be.
+MedEighty Ikr
I got more out of this video compared to a semester of school
+MedEighty yeah I feel the same too. It was a great lesson indeed.
same
+MedEighty agreed
Cave walls are the best for storing written data ...
Nah, erosion gets them in a few thousand years, unless you are lucky and find a very stable area.
Paul Mahoney
oh ... I was talking about the walls of the caves on the moon ...
ha ha ha...
roflmao....
@@morningmadera nah, man, moon's absence of dense atmosphere makes it vulnerable to meteor hits so it's also isn't the case
But yeah, storing data in an analog form with the good enough protection is the best way to do so. Like the message NASA sent to space which was supposed to last millions of years was written that way on a golden record
1:22 ted ed predicts the press f to pay respects meme
hahah
:O
Well aowkaowlaow
Its a meme since 2014.

Pretty awesome high level explanation. Once you learn more about the deeper layers, the more unbelievable it gets. But remember that this progress was made over thousands of years, from melting metal to creating nano sized circuits. It's overwhelming to suddenly try to understand every aspect of computer science.
Not that much since you are flooded with lot of resources to cover them all, your time and efforts are the only sacrifies to give.
I like the little happy faces.
Yeah, they look so cute :)
OMFG. Is it like Hell looks like?
@Readme .txt What are you even talking about?
jessiem6694 VERY
Kinda creepy how wide his mouth opened
So this was a very informative video and all but I can't get over the drawing of the 6 transistors holding hands. It was so cute and I'm so happy they're working together good job TED-Ed animation team.
+Jack Pinto Indeed, this is how infotainment works, to teach and to keep your attention by these cartoon stuff.
4:45 Happy computer memory friends :D
@@SamBorgman you prune it is not cartoon stuff at all in this Video
7 years later, I used this video the night before a test. The only study material that actually helped me during the examination, could remember the information due to the characters holding hands etc. Almost didn't even click on the video since it's so old. Amazing!
TED: When you Press "F"
ME: Oh, nice prediction
And this is the short story of me freaking out and instantly backing up my drives...
+Krisztián Szirtes
Which shows, that you seem to be a smart individual. Not backuped data = irrelevant data
+Krisztián Szirtes hahaha me too
+Frank Schneider Not in that sense, dude. Backup as in safety-copying all my important stuff.
Namely 4 gigs of music and 200 gigabytes of photos.
@@krisztianszirtes5414 lol only 4GB of music? you use mp3?
Me 2😂😂
This video is one of the best ones i've seen on youtube. It's Beautiful.
+Super Smelly Bob
Me too
agree
Same,
+Super Smelly Bob i totally agree
Very agree.
I've been wondering how this whole thing works for a while now.
This video answers my question perfectly
trust me, you still don't know how this works, this video was very basic over the top information about how memory works
@@BangMaster96 Well, even pro's won't know how it works unless they're working on it directly since so much knowledge and optimizations go into it.
But I'd say most of the important information is in this video. Stack fast, ram slow, and we will all die.
That was really well done! Love it.
indeed!
Would love to see a similar episode on quantum computing technology!
Yeah. And biological memory
it's a 1 and zero at the same time, and has a x and y axis really really simplified version xD
+Andrew Jones Well, there's quite a lot more to it though, like the 0+0, 0+1, 1+0 and 1+1 quantum superpositions and just how it works overall. I think these two topics would make amazing videos
+Bethel Imaging And the new ram that runs at 5% the energy and 500% the capacity through a clever mechanical arrangement that stacks memory chips on top of each other.
Thanks for giving me more information about my study field (IT) than my actual school that I go to for on average 7 hours a day 5 times a week and learn basicly nothing. I know, IT is about learning stuff on your own, but when I try learning more I just get confused or completely lost. So yeah I am really happy for channels like those that can put it this simply. :)
Fuck this. Science is magic.
+workwork damn My thoughts exactly.
+workwork damn sCiEnCe aRe mOtHeRfUcKiN MiRaClEs hOnK :o)
Fucking magnets, how do they work?
a computer is just a metal box that uses electricity and magic to do things
The script, voiceover, music and animation of this video was PERFECT.
+marcusezikel Welcome to ted-ed
Beautiful! For someone who isn't interested very much in a way computers work, and doesn't have any deep knowledge about computers, I think there isn't a better way to present this.
As a Superhero in training, I appreciate this video. Have a Heroic day!
1 minute into the video and I'm here to comment before it ends.
The editing is so visual. Literally almost every word is animated in one way or another. (Especially the sice, cost and speed one) And the idea to put smiles on the hardware components to make them look friendly and humane has literallly made me "think from the hardware's persective."
You mean size
Technology advancements ..
I went almost mad while studying basic transistor functions and see these memory, CPUs these are so so damn complex omg..😰😰
Super Respect to those who have made these possible 🙏🙏
this is true my brain is refusing to learn computer language i want to learn but still its complicated :D
4:46 don't go VSauce on me
Lol
+David Ndiulor Except Michael would have said "but what IS immortality?" And then gone off on a 10 speech about it.
+James Greydanus **creepy background music sets in**
+David Ndiulor hahaha
+NightFury so true!
That's why I always treated my computer I built like a baby. I get afraid when the power goes out, and my computer shuts down. That's what computer enthusiasts wishes never happens, like me.
I've seen many "how computers work" videos but it's all still magic to me
This is REAL teaching! Direct 'No BS' education. I like that. Thank you!
This was the best video in youtube I have seen so far!
good job TED
yay! i love videos relating to tech. I'm leading an intro to computing course at my university for non-tech majors and these videos are so helpful! for both myself and the class!
+Yesenia Torres
Do you show your class these videos ?
TED-Ed is great at explaining these sorts of things in a understandable way.
This video gives the answer of why and how in each second of it. GREAT EXPLANATION and can be understand by anyone easily
Seeing ted ed videos is always worth time, always
Though I think you should've also added that unlike magnetic and optical storage, SSDs can be read an infinite amount of times, just not written to as much as magnetic and optical storage.
SSDs do not have infinite reads
Ted-ed has literally got a video for anything and everything that I can ever think of!
Sometimes CZcams randomly recommended me this type of valuable videos. Thank you.
What a video to explain this complex topic..simply great
Less than 10 years? OMG I gotta buy new harddisk drive!
If you use alot foryour hdd 24 hours , less than 10 years. example : Server machine.
Don't worry We use pc, 10 hours a day, less than 20years.
unused hdd life is 5 year.
+Michael McNamara when it is not charged for 10 years
@Bammerbom I assume this means "not used for 10 years" ?
My hdd (old) survived 11 years, still working.
Wow, I️ thought this was just gonna be about how a RAM works - then you got to that and the HDD and SSD in 5 minutes. You guys are amazing.
I loved this video, very well done. It dose a very good job of getting a lot of technical information out in a way the is relatively easy to understand. The animation that was used really help to visually show something that can not be seen. I know that it is a brief overview of how the ram works but it explained a lot of what can take hours to breakdown. Thank you for a very well made video.
Really nice video. 👌
To add that: registers also form an important component in the memory hierarchy which are generally implemented by flip flops.
They are one of the most expensive components!
Happy learning! 😊
Couldn't get it ???
@@muzamilzaman7463 register is an electronic component consisting of many flip flops connected together. a flip flop is a 1 bit memory device it can store information of just 1 bit so the connection of flip flops can store multiple bits. Each flip flop is made by using some transistors hence using many of them is costly.
"For now immortality remains out of reach for humans and computers alike."
As a computer engineer, this is the truth of life...
this actually is super simple on the inside and goes on to get simpler but the final product is super complex (just another example how simple things make complex things when put together???)
I loved it! I have done my own research of the various parts of a computer and though personally done research is important, this video definitely expedites that process. 👍
4:28 looks like my 2012 data is gone now.
Amazing as always Ted!
Ted-ed is the only CZcams channel which I trust the most.
Easily one of the best videos I have ever watched. I will watch this once a week problem.
Unlike humans, the data stored on drives can easily be copied to other drives, creating virtual immortality for the data even though the hardware dies fairly quickly.
Actually Hard Drives will last for up to 10 years
This is nicely done and explained =)
great job done by kanawat senanan . typical and very much complex theories and facts are explained simply by using smooth animations . just loved it. keep it up.
When I am struggling with Computer Organization of Computer, I found this video. Thank you very much !!
Name:Yvon Colit B Takan
Section C
Pretty awesome high level explanation. Once I learn more about the deeper layers, the more believable it gets.Memory is the electronic holding place for the instructions and data a computer needs to reach quickly. It's where information is stored for immediate use. Memory is one of the basic functions of a computer, because without it, a computer would not be able to function properly.
the thought of my optical disks losing data is quite....disturbing to me.
As far as I know there is no dye in cds (it’s all reflective spots in the surface) and therefore the plastic it’s self has to degrade, I guess it’s more then 10 years for cds (we probably would have noticed by now)
I love ted ed it really helps me understand the world around me a lot better.
This is one of the best videos I've ever seen!
1:22 press f to pay respect

I wish everything could be explained like this
every aspect gets so deep!!! i need a video on each part. like magnetic films storing data? which i know about, but i do want to see it represented. i want to see a slooooooow illustration of the lights going on and off for 0's and 1's and the processor doing its thing in real time.
This definitely makes me curious and makes me understand that there is so much to learn and understand.
Make more riddles!
So basically if we humans suddenly disappear right now, and one thousand years later, an alien civilization discovers earth and also discovers the servers of Tumblr, they will not be able to see the stupidity of humanity?
For the aliens' sake, I sincerely hope not.
+hereLiesThisTroper Luckily not. But they might see the tumblerina-policies that have made its way into society. In the same way that we can see the fall of other once great societies.
I doubt an HDD would remain usable 1000 years into the future.
@@DLBBALL Thats if the pressure from the screws keep the rubber seal in shape, besides. Certain environments can preserve metal very well, not sure about motherboard PCB's though.
Maybe cockroaches will take over faster.
This was... actually accurate. Well done TED-Ed!
I'm glad I found this channel!
Sooo, if you really want to store something for millenia, books are still the way to go?
+Anston [Music] Even better : stone tablets.
+RedstonePF Gold tablets.
RedstonePF The data density is quite low on those.
Anston [Music]
Sometimes, there are some sacrifices that must be made for posteriority.
+Anston [Music]
To be serious at the moment the best way for long term storage is: either: hard discs and regularly copying or: micro film. Data density is higher than book
/paper and the plastics is also lot more resilient than paper.
Great now i can make a computer !
One of the best videos I've watched on CZcams
"Immortality remains out of reach for humans and computers alike" thats deep.
Can you do a more modern take, Harddrives and optical drives are basically obsolete in household PC's now and there are different types of ssd's and you used a flash drive as that reference. A better example would be the 2.5 inch sata ssds, the sata m.2s, and the more modern m.2 nvme storage. There are differences between these more modern types of storage and would be better addressed on a channel like this because people les tech oriented would come to places like this for help when making purchases for their electronics.
Incorrect many laptops still have hard drives and optical drives(my 6 year old laptop has them)
Surprised the word volatile was not used this video...
+Tyler Caporaso
I was expecting it here 2:43
jargon
I wish all of TED-Ed videos were like this.
Thanks for the shortened introduction to the memory system.
4:03
The bits doesn't feel so good....
I like how they specifically pressed f 😂
The best video about computer memory I have ever seen. Explanation is good because of text and pictures.
who ever came up with all of this should be known by everyone in the world. imagine how much hard work that would be.
It'ss not one person, the invention of computer memory took decades with thousands of computer scientists, mathematicians, and engineers.
Happy faces to not seem like it's teaching you something :)
RIP MY DATA!
Hello new computer..
I thought that i will not get any of the explaination, but somehow i understand everything he explained. Ted ed have a really good job at explaining thing
To me, its always amazing and "magical" how you can just take a bunch of 1 and 0 and turn it into This.
2:42 I feel like thats me on the wall.
We really take electronics for granted and not think of how complex and difficult to make them are.
I actually found a recent video on Facebook in which data was stores in water, in about 5-10 drops of water there were 1 million copies of what I think was a DVD film, I'm not entirely sure what it is used for but it shows that we may possibly find a whole new way of storing data compared to what we have now, it's quite fascinating.
truly great explanation. thank you
I have a literature paper tomorrow but why not
Muy interesante :D
This will make people's brains grow
We should store data on stone walls. It will last for thousands of years.
No it won't and that would also male it inacessible too
10? Crap! 10 years! I'm out of time! I have to back it all up!
***** Same mines 10 years. It's being spinning for 6.
It can last over 10 years
This Video is quite old and outdated now
Thank you for making such a good video. Perfectly explained and beautifully drawn.
I love how extremely happy these computer parts are
How much "detodated" RAM is there?
Wam*
1:10 why is there a hard drive in a PCI-E slot it doesn’t work that way
even worse, it's in a PCI slot.
Although it's not completely impossible - PCIe to SATA expansions cards do exist... the hdd just doesn't slot directly into the slot like that
I love these videos about how computers work.
Amazing video, it is perfect for any person trying to understand memory systems.
Yeah SRAM is akward... in my native Polish it's something like "I'm shitting". How wonderfull...
waw
+MuchozolF Yeah, and fluorescent lightbulbs manufacturers name OSRAM means "I will shit (on something)".
Adam Kudelski This name came from osmium and tungsten elements which are called "osm" and "wolfram" in Polish.
1:20 why did he press "F"?
Press "F" to pay respect
The fact that we discovered this is amazing
This nearly made me cry and I don't know why.
Gross so if we stopped making memory storage devices then all current devices will degrade over time until it is gone...
+xxuncexx yes. but that can be true for nearly anything
