    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.

    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.

    This video had a few good points but was marred, and it could confuse people. Had you simply mentioned _"parallel to serial compression"_ (like USB) requiring (a chipset) doing processing of it, it would have cleared up the "magic" mystery of why and how people managed to get from the data rates of parallel to those of serial. The pay-off and trade-off would start to dawn on them because it isn't "magic". You could then have simply "name dropped" Fourier mathematics, and then people could at least look it up in a book or online. There was a reason parallel existed (high data rates and also acting as the first GPIO), and yet form your video people could walk away thinking serial should have only ever been the way forward and that somehow there was no hurdle to get the benefits of parallel into serial. You don't even have to "explain" the complicated stuff. Just "mention" the word and then people can have a look.
    The notion of pins being prone to damage is *not* an argument against parallel when comparing to serial. Not only can you wire to (and thereby adapt) the shape of something else like an rj11 or rj45 connector for a parallel (so the size and pins can be smaller), but also a serial (e.g. a great big RS232 null modem cable) can be about the same size as a parallel printer cable.

    Fun fact: You can get a PCIe x4, 8, 16, etc card working in an x1 slot by either sawing the extra pins off the card or cutting open the PCIe connector on the motherboard. I had to do this once, to get a video card to work in a PC that only had 1 x1 slot remaining. (The x16 slot was occupied by an HBA.) It worked reasonably well, although the drop in bandwidth/performance was apparent even at the Windows desktop.

      well 12 years ago was in 2005 and USB was basically already the standard and SATA was gaining popularity over IDE. That and with IDE there was always a chance that the pins would bend if you didn't pull the cable out exactly at 90° and it was a huge chore to bend them back. Which, although it usually doesn't require IT assistance, is still a pain in the ass.

      you dont usually remove parallel ports as often. thats why most of the external parallel ports have screws and screwholes and the internal ones are, well internal and not plug and play. if you were to plug an IEEE 1284 connector into a port multiple times a day it would break in no time. but usually you don't actually remove or insert a plug a whole lot.

    This brings back memories from when PC parts were more expensive, and repairing parts was more common rather than disposing of them, and delicately straightening those bent pins on drives, cables, and motherboards.

    You didn't mention the speed of chipset meaning there was a limit to baud that each chip could interpret the data in serial. It was cheaper to put them in parallel and feed the more expensive CPU that way than to buy a chip fast enough to talk in serial at the same speed. It wasn't until these chipsets became more powerful and less expensive that serial was able to take over. It also helped that we were reaching limits with parallel speeds anyway due to the aforementioned crosstalk, etc.

  • @manuelruhguevara1601
    @manuelruhguevara1601 7 років тому +1

    USB does not have one data line in each direction. USB uses differential data signaling, this means that one data line can be mapped to 2 physical wires, one being D- and the other D+, so when one wire goes high voltage, the other goes low voltage. Differential signaling allow serial communications to be faster because they are able to send data with lower voltage swings without being affected by ambient noise. As for the clock it goes embedded in each data signal and is reconstructed by the receiver.

      Well, I suppose a machine-gun is just a gun that operates by using mechanisms for reloading, ejecting, and whatnot instead of needing the input of a human every step of the way.
      And automatic is a general term I suppose, so he's not that incorrect.
      So long as it functions by itself without someone having to baby it every step of the way I suppose it's automatic, and if it does that with mechanisms, it's a machine.
      I dunno, though.

    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. :)

    so why does usb 3 and 3.1 usb more than 4 pins? are there moultiple serial sonnections like pcie?

    I’m assuming this means that each wire in a USB cable (for example) handles one set of information bit by bit while other wires can handle other sets of info simultaneously. Parallel connections have every wire containing one bit of each byte so they’re effectively working together all the time whereas the wires in a serial connection operate independently

    Please do a video on PCI vs other serial protocols like I2C

    Why couldn't the parallel standard be improved to allow for the pins to transfer data independently like in PCIe?

    So wait if these are so technically different how do ide to sata adapters works? Or does it use a dram chip to store the data and then convert it from serial to parallel?

    I thought crosstalk was between a receiver and transmitter (side by side) wire. Cause the transmitter has much more signal in the beginning of the wire and after some distance (that the receiver's signal is not faided that much) had electrical interference

    There are definitely some limitations to standards like USB. Some industrial applications actually do work find parallel connection more reliable if they need a specific thing to be refreshed as quickly as possible. A serial bus really doesn't lend itself quite as well to real-time applications, and a couple of unusual examples would be USB keyboards not having NKRO, and the fact that an SNES controller can be more responsive on the original hardware than a USB knockoff can be on a PC. USB in particular has the limitation of relying on the OS polling a certain number of times per second, where some parallel standards can use straight up hardware interrupts, so the device can tell the computer about state changes as soon as they happen rather than waiting for the next poll. I'm kind of glad the PS/2 ports are still around.

      USB keyboards not supporting NKRO is a common myth. USB mice are also not any less fast or reliable than PS/2 mice. USB has matured and evolved enough at this point that the advantages PS/2 once had are pretty much moot.

    I have a whole bucket load of what appears to be DB 37 Serial data storage cartridges (predecessor to USB thumb drive by the looks of it, to me at least) and I'm trying to figure out more about them.
    I have these because my Grandfather custom built a few barrel organs in his life time, usually barrel organs are analog instruments which use rolls of perforated paper to produce music, my Granps being the absolute 1980s-1990s tech wizard he was, completely rebuilt the guts of the organs, turning them digital. They read MIDI files off of these extremely obscure, dated 37 pin cartridges (I think serial DB 37), the cardriges themselves are totally black plastic, about 3x2x0.75 inches with right angle edges and corners, and absolutely no branding or text on the device other than the hand written labels of what songs are on each cartridge.
    Anyway, I inherited all this stuff and would love to figure out more about it all, I'd LOVE to be able to hook up some of these cartridges to modern hardware and see if I can write any custom music to be played on the organ. I'm an actual musician, which is why I inherited all of this, so it would be a blast to give some new life to my Grandad's old project.

    0:58 hella wrong. USB 3.0 has two seperate "lanes", so it can send and recieve at the same time.
