  • actually they would be correct :

    USB began as a protocol where one side (USB-A) takes the leading role and the other (USB-B) the following role . this was mandated by hardware with differently shaped plugs and ports . this made sense for the time as USB was ment to connect computers to peripherals .

    however some devices don’t fit this binary that well : one might want to connect their phone to their computer to pull data off it , but they also might want to connect a keyboard to it , with the small form factor not allowing for both a USB-A and USB-B port. the solution was USB On-The-Go : USB Mini-A/B/AB and USB Micro-A/B/AB connectors have an additional pin which allows both modes of operations

    with USB-C , aside from adding more pins and making the connector rotationally symmetric , a very similar yet differently named feature was included , since USB-C - USB-C connections were planed for

    so yeah USB-A to USB-A connections are explicitly not allowed , for a similar reason as you only see CEE 7 (fine , or the objectively worse NEMA) plugs on both ends of a cable only in joke made cables . USB-C has additional hardware to support both sides using USB-C which USB-A , neither in the original or 3.0 revision , has .



  • autistic complaining about units

    ok so like I don’t know if I’ve ever seen a more confusing use of units . at least you haven’t used the p infix instead of the / in bandwith units .

    like you used both upper case and lowercase in units but like I can’t say if it was intentional or not ? especially as the letter that is uppercased should be uppercased ?

    anyway

    1Mb

    is theoretically correct but you likely ment either one megabyte (1 MB) or one megibyte (MiB) rather than one megabit (1 Mb)

    ~325mb/s

    95mb/s

    and

    9mb/s

    I will presume you did not intend to write ~325 milibits per second , but ~325 megabits per seconds , though if you have used the 333 333 request count as in the segment you quoted , though to be fair op also made a mistake I think , the number they gave should be 3 exabits per second (3 Eb/s) or 380 terabytes per seconds (TB/s) , but that’s because they calculated the number of requests you can make from a 1 gigabit (which is what I assume they ment by gbit) wrong , forgetting to account that a byte is 8 bits , you can only make 416 666 of 4 kB (sorry I’m not checking what would happen if they ment kibibytes sorry I underestimated how demanding this would be but I’m to deep in it now so I’m gonna take that cop-out) requests a second , giving 380 terabits per second (380 Tb/s) or 3.04 terabytes per second (3.04 TB/s) , assuming the entire packet is exactly 114 megabytes (114 MB) which is about 108.7 megibytes (108.7 MiB) . so anyway

    packet size theoretical bandwidth
    1 Mb 416.7 Gb/s 52.1 GB/s
    1 MB 3.3 Tb/s 416.7 GB/s
    1 MiB 3.3 Tb/s 416.7 GB/s
    300 kb 125.0 Gb/s 15.6 GB/s
    300 kB 1000.0 Gb/s 125.0 GB/s
    300 kiB 1000.0 Gb/s 125.0 GB/s
    30 kb 12.5 Gb/s 1.6 GB/s
    30 kB 100.0 Gb/s 12.5 GB/s
    30 kiB 100.0 Gb/s 12.5 GB/s

    hope that table is ok and all cause im in a rush yeah bye












  • autistic complaining about improper use of SI and SI adjacent units , going into a bit of self parody at the end

    please fucking capitalise units properly , the most valid interpretation of “mbps” is millibit picosecond which is invalid anyway (should be femtobit second or fb s) and also not a unit of any kind of speed , not that you are asking about speed but likely bandwidth , but also in this specific case , ignoring that you use this stupid per construct , leaving it to interpretation which letter is meant to be capitalised and which lower case leaves megabits per second (Mb s^(-1)) and megabytes per second (MB s^(-1)) (of course milibits per second and milibytes per second are also units of bandwidth) , and also because bits and bytes are involved , are you using the mega- prefix per SI or , I would argue incorrectly , per JEDEC (as in 1 KB = 1024 B ) , I don’t know because you have shown a complete disregard for units and all they represent , for everyone who takes the time to understand , learn and properly use prefixes to convey a specific meaning , in a way that cannot be misinterpreted . You may not think this is important because “oh Lily you understood me anyway” and ? you have shown a complete disregard for all that anyone with a computer science degree should stand for , shown no intention to properly understand how the more and more computerised would around us works and for what ? so that your fingers can use a few less calories , putting of the heat death of the universe by an unimaginably irrelevant amount , which you will unknowingly spend anyway when you hear a bird sing across the road , is that really worth it to you ?
