So we ended last episode at the start of the 20th century with special purpose computing devices such as Herman Hollerith’s tabulating machines. But as the scale of human civilization continued to grow as did the demand for more sophisticated and powerful devices. Soon these cabinet-sized electro-mechanical computers would grow into room-sized behemoths that were prone to errors. But is was these computers that would help usher in a new era of computation – electronic computing.

  1. Next video: “How to overclock a vacuum tube”

  2. 3:18 Did anyone else think of the smashed bug in the printer which sets events in motion in the movie "Brazil?"

  5. 영상만들어주신분과 자막만들어 주신분께 감사합니다.

  7. Why is she speaking so quickly? Love it tho

  8. 6:35 The C in ENIAC stands for “computer” and not “calculator”.

  9. My goal is to spend the most time on the computer than anyone in history.

  11. When you realise that for the first time, most people here are actually professionals and not desperate kids grabbing at a last minute oppurtunity to cram stuff

    Unlike me. Sigh.

  12. mam, u told that 140 relays need to be changed every day… please tell me how u, calculated the no of relay

  15. I used this for my homework, and it’s a very good source👌

  17. Who else is watching this on their tabulating device

  18. Watching day before computer science exam 😢😢😢

  19. grace hopper said there was a bug in it?
    thats where you got the term computer bugs?
    when you say grace hopper, i say grass hopper!!!

  20. In the future I will share these presentations with my kids, not school.

  21. 1:04 Harvard Mark I
    2:33 Additions, Subtractions, Multiplications, Divisions. Computer Bugs
    3:34 John Ambrose Fleming, Thermionic Valve.
    Lee de Forest
    4:55 Triode Vacuum Tubes
    5:31 Electronic Computing. Colossus MK1. Alan Turing
    6:35 ENIAC
    7:40 A Transistor. Computers get smaller, Computers get cheaper
    9:35 Silicon Valley

  22. My teacher is making me watch this it’s pretty stupid if you ask me lol Dislike this video

  23. no offense to the lady doing the talking on the video,but Im gonna suggest that your should speak a bit slower for the sake of learning,again no offense,just an observation,you talk way to fast for a video that is meant to teach people,content is awesome but way to fast paced. we know it will drive the video to get heavier and longer but it will be nice to learn on a slower rithm

  24. Wow this course is GOD DAMN HELPFUL and REALLY AMAZING 😍😍😍😍 Thank you so much 🤗

  26. These videos are immensely informative thanks so much

  28. 8:42 that's showing a vacuum tube and a film capacitor side by side as they're talking about the size of a transistor to a vacuum tube am I wrong? Maybe I just don't know what early transistors looked like

  32. Omg this chick so ugly I can't even use this 😒. The guys at least wear decent clothes and try to be funny. She in a ratty t and not funny at all

  33. Question: You said Harvard Mark 1 had 3500 relays and if each relay has 10 years of life. Then how you came up on the conclusion that you have to replace 140 relays every day. I didn't understand math behind this. Could you/anyone help me?

  34. From a guitar guy's view
    Very appreciate that you have a valve in your hand.
    I can't get focused on anything with these fantastic looking bulbs!

  35. أين نجدها مترجمة أو مدبلجة للعربية .

  36. Great channel

  45. 6:22 …so I pressed F10 to "Save", but it just muted the audio.

  46. Bloody brilliant videos

  48. I'm pretty late to seeing this series, and a new watcher of Crash Course, but I'm hoping to eventually get a degree in computer engineering and this is some of the most fascinating material I've ever watched, presented in a manner that my dumb brain can understand it. Thank you very much!

  49. "sticky, slow, and just plain unreliable" – sounds like me Lol
