How Computers Work: Binary & Data

You’ll hear that everything’s “1s and 0s” in a computer, but what does that mean? Find out how computers represent numbers, words, images, and sound.

    Still, what I don’t understand is that how these electrical signals converted to 0 and 1???🤔🤔

    Pythagoras is dancing in his grave.



  10. Michael Landon on September 7, 2019 at 3:20 pm

    Can any one tell me how they organize and categorize these datas so they aren’t jumbled? And how they do it with so so so much data?



  11. SimonFox YT on September 7, 2019 at 3:21 pm

    Transistors aren’t just wires!



  12. Eng.Mervat ghanem on September 7, 2019 at 3:21 pm

    I really appreciate your effort to make such video , thank you so much

    Very good, my one year old finally gets it.



  14. Kuzenbo on September 7, 2019 at 3:22 pm

    She seem’s like a pro on binary stuff if you know what I mean xDDD

    what that !!

    This was a very good video! The visuals were a great addition and were well made.

    I think the video would have been more effective if while talking about decimal vs binary a little bit of history as to why we chose computers to read binary instead of decimal was included. Something I wondered for awhile was: "Why don’t we have computers read ten different states of something so that it could read straight decimal?".

    I’m about to present a speech about how computers work, using bits of information. This video jogged my memory and helped my confidence a bit in how I’ll approach my speech. Thanks!



  20. JY Panda on September 7, 2019 at 3:29 pm

    this saved my life, finally i understand what is binary, thank you sooooo much~



  21. Darius NoName on September 7, 2019 at 3:29 pm

    Can anyone expain to me, where instructions of what binary means ar stored in a computer(how computer can decide that 10 is 2, or how some binary code means as a letter). And how do we program that?



  22. Michael Goodman on September 7, 2019 at 3:30 pm

    that was actually very useful to understand.

    I found Limor’s lip ring and hair color too distracting to concentrate…..at least there was no background music …so that was certainly worth a 1



  25. LeCoureurDesBois on September 7, 2019 at 3:37 pm

    Thanks now I can build a calculator



  26. Arjun Singh on September 7, 2019 at 3:37 pm

    one of the best videos i ever seen in youtube thanku



  27. Amit Barjatya on September 7, 2019 at 3:41 pm

    This is really informative and helpful….!



  28. Jaemin Choi on September 7, 2019 at 3:41 pm

    thanks for making this video!



  29. Damian Clarkson on September 7, 2019 at 3:42 pm

    This video should be the one used in schools everywhere to understand binary. Iv watched so many others and struggled but this one just makes sense. Brilliant!



  30. Ronan Rox on September 7, 2019 at 3:42 pm

    Couldn’t you be technically precise?



  31. Rajesh Raut on September 7, 2019 at 3:43 pm

    How will computer understand that ‘00001’ is ‘A’ , ‘a’ ,or 1



  32. M Iftekhar Abir on September 7, 2019 at 3:47 pm

    This is the video that i was looking for … I’ve always wondered how binary works with other thing except numbers



  33. Nick Calingo on September 7, 2019 at 3:47 pm

    My brain just died a little…



  34. Hello 3 on September 7, 2019 at 3:47 pm

    This is terrible. I’ve had shite with better structure than this video

  37. Zzzzzz... on September 7, 2019 at 3:50 pm

    I guess I wanted something a little more complex, this doesn’t really actually tell you how computers work. There should have been talk on what are NAS gates and terminology like that. So electricity comes from the wall into the power supply and then the power supply delivers the necessary power to each component. Billions of transistors turn various signals on and off, but how does the transistor sort of "know" to turn the switch over to either on or off position? How does machine language, that are binary numbers, work with the hardware? Is one of my premises wrong? Could someone educate me on how computers work on a more complex level?



  38. Quavo Huncho on September 7, 2019 at 3:50 pm

    This video is really bad. Pls delete it and move to Russia



  39. Jason Miller on September 7, 2019 at 3:53 pm

    I like to smell ass



  40. Ima Lallawmkima on September 7, 2019 at 3:57 pm

    And that is how you store data in images eg: virus



  41. Chiagozie Ogbonna on September 7, 2019 at 3:59 pm

    The numbers Mason! What do they mean?



  42. Enver Dashdemir on September 7, 2019 at 4:00 pm

    How many bit is the 3rd wire?



  43. sachin awesome on September 7, 2019 at 4:02 pm

    Thank you



  44. Ronan Rox on September 7, 2019 at 4:04 pm

    How can you represent something with numbers when numbers themselfs have to be represented?



  45. IZAAC SEGURA on September 7, 2019 at 4:05 pm

    It is noice



  46. DinodollGaming on September 7, 2019 at 4:05 pm

    So you can make a memory wheel to see the inputs that are activated



  47. Arul R on September 7, 2019 at 4:07 pm

    but how computer knows we got 1 so we want to switch on the current



  48. Ann RT on September 7, 2019 at 4:07 pm

    Thank you so much for making my basic idea clear. If you need 8 wires for a single letter,how computers are so small,can you explain briefly?



  49. sawajiri100 on September 7, 2019 at 4:07 pm

    Digital Computer is best man creation. without this. we have no here to watch and say everything



  50. Mahawa Sackor on September 7, 2019 at 4:08 pm

    WOW I NEVER NEW I COULD LEARN THIS 0w0
