    How much real data can be sent in 1 s over a synchronous link with a bandwidth of 512 kbps, without hardware and software compression?
    I've seen a question on the forum before, the answer is over 55 kB.
    Why? Please give me a precise explanation.
    Since 1B=8b, then 512kb/8=64kB

    512kbps : 2 = 256kbps because it's synchronous
    256kbps : 8 = 32kBps it can send in 1 second
    I hope its good.

    Doesn't the author mean Aero2?

    I think I will surprise you, I get 62.5KB of data :D

    There are also checksums, control packages and other things that make life difficult for programmers, so it will be even less.

    apart from other matters, only theoretically the bandwidth of the connection
    512/8/1.024=62.5
    throughput is wka data is in K

    I thought the author meant how much he could send. But unless I understood.

    In my opinion, that's how a kilogram is not equal to a kilogram
    speed small k = kilo, decimal 10 to 3 = 1000B
    big data K = Kilo, binary 2 to 10 = 1024B

    I don't understand why I have to divide it by 2
    After all, the type of connection does not matter, only what speed we have assigned
    it doesn't even matter if we receive or transmit in a given direction, we have 512 kilos

    I meant that if the link is 512kbps and it is synchronous, the upload and download are equal. So we divide by 2

    Does your colleague distinguish between the terms: synchronous - asynchronous link from symmetrical - unsymmetrical?
    With a 512kbps synchronous link, division by 2 makes no sense.

    And I actually got those ideas wrong.

Topic summary

The discussion centers on the amount of real data that can be transmitted over a synchronous link with a bandwidth of 512 kbps without compression. Various participants provide calculations and insights, with some suggesting that the effective throughput is around 62.5 kB/s, while others argue that factors like checksums and control packets reduce this figure further. The debate includes clarifications on the distinction between synchronous and asynchronous links, with some participants mistakenly dividing the bandwidth by two, assuming equal upload and download speeds. Ultimately, the consensus leans towards a theoretical maximum of 64 kB/s, but practical considerations suggest lower actual throughput.
