What's the Difference Between Parallel and Serial?

At first, parallel connections might seem like better ways to send data - so why are most modern interfaces like USB serial?

That brings back nightmares about removing IDE cables. You couldn't pull the cable itself because it could damage it, which meant pinching both sides. When you finally got it loose, your hand would slingshot out and you could cut yourself on the sharp edges that used to be in cases.

You guys should do a collab with LinusTechTips

My sister heard you talking and said "Is that bob the tomato from veggie tales?"

I loved the machine gun/shotgun analogy. Genius!

3:33 explaining clock recovery encoding protocols like 8/10 might be relevant for future videos, as it helps viewers understand how high speed communication work without a dedicated shared system clock between components. Also useful for understanding why 1Gbit=100Mbyte.

Other relevant topic: Could be interesting to also cover the actual pins on a cable, e.g. USB, Ethernet, SATA, and wtf they actually do, and cover differential signaling and how it reduces interference problems.

Sorry, but saying "USB got one data line in each direction" is false.
USB 2.0 and lower only has D+ and D- as signal lines, but this is a differential pair. Meaning, that it basically carries the same information at the same direction at each time (half-duplex), but the signals are the inverse of each other to block outside interference.
From USB 3.0, the cable got two more pairs for each direction (SuperSpeed tx/rx), but the old pair is still there to make your statement false and to confuse everyone.

concise, well thought out, and well written. Keep up the good work, whoever wrote this episode and did the animations!

[robertwitt]

seriously an awesome video man! studying right now for my embedded miscroprocessor systems design class right now and you are motivating me to study!

[Velo]

Dude! You have one hell of a YouTube channel. That energy is exciting. I appreciate what you offer in learning- fun graphics and easy to understand. Keep up the great work.

[webbophone]

Thanks very much! Been trying to wrap my head around this for a while and I am glad I found your video!

[Tobiasize]

3:32 tfw you forge a pc in a dying star

[bushmasters]

great visuals to help. thanks for your content.

let's all eat cereal at the same time so we can be parallel.




and no, it doesn't all have to be the same cereal :)

I needed ALL OF THIS ENTERTAINMENT. Reminds me of how engaged I was watching Bill Nye the Science guy as a kid. He made me fall in love with science and you make learning boring info easy.

Great video! :)

I would find it very interesting if you could do a Techquickie on computer component power consumption, particularly that of CPUs and GPUs and what constitutes it. What does the electricity actually do inside the components - what is it needed for? Also, the GTX 580 from around 7 years back and a modern GTX 1080 Ti both have similar power consumption yet the difference in performance is, of course, absolutely massive. Similar trends can be seen on CPUs as well. What has allowed these huge advancements in power efficiency and can we expect this trend to continue still as time passes on - is there still much that can be done to improve power efficiency? Where are the physical limits as to how low power consumption could be dropped in the future for a given level of performance (a certain amount of FLOPS)? Also, how are CPUs used on mobile devices and laptops able to achieve such low power consumption ratings despite still being fairly powerful?

It would be very interesting to learn about these things! All the best to the whole team and thank you for making these videos. :)

Linus thanks for helping me learn lots of stuff daily. Hailing from Nigeria as me and my buddy watch you all the time

[DanneManne]

You are King Linus! Continue with the good work !

[maurices.]

You took a funny example with the soldiers. Made my evening today.

[suitub]

Make great great great sense to me! Thank you so much, dude
