I've been programming since punched cards. My first exposure to a "terminal" was 110 baud on a AT&T Model 33.
I could easily keep up with 2400 baud modem traffic. 9600 was the first that was faster than my eyes.

I live in a new house which is connected by optics, and the provider offers 10, 25 and 100 Mbps plans. I could afford the 100 Mbps quite easily, but the truth is I would not utilize it. I haven't hit even the limits of the 10 Mbps plan yet.
Is that dialup? When you run the internet speed site, it gives you a link to copy paste to share with friends. Then you come back here and choose the "img" button (fifth to right in the row of buttons) and paste that URL.
We ask to credit where the image came from. Didn't do that here since it is obvious. But if you post a pictures of some cute kittens, crediting the source is appreciated.
It's supposed to be "high-speed"...256Kbps down, 128Kbps up. Which seems to be exactly what I'm getting.
Not likely to get any sort of fiber out in rural SK anytime soon - I read on the news this morning they're finally putting it in the two major cities.

For normal telephone signals, there's a limited bandwidth allocated on the telephone line. Old-fashioned modems work by translating bits into sound, which gets transmitted over the normal telephone channel which you normally use for speech. Because the bandwidth of that channel is limited, there's a theoretical maximum speed, which is probably somewhere around 64 kbps.
Note that this limit isn't because of the copper wires - the wires can easily carry signals of much higher frequencies. For example ADSL works also over the normal telephone wires, but it uses another frequency band than the band that's normally allocated for speech.

It has to do with bandwidth multiplied by signal‑to‑noise ratio.
