"Maaaaan, you're from waaay back or something. Ugh. Vera or Googz would probably be better at explaining this than I am, but I guess I'll do my best. Okay, so once upon a time, in like... the stone age or something when our parents were teenagers, they were stuck on dial-up. Outside the computer we communicate with phones. Well, dial-up used those phones to connect them to the 'net. Which meant only one person could access it at a time, and no one could use the phones. That was a problem, so they developed better things. Cable modems, DSL, wifi, stuff like that. Now we can use the net at the same time, or tie up the phones, not that anyone uses those old phones anymore anyway, and our bandwidth is like a gazillion times faster."

[How best to make it clear?]

[Ah.]

"Here, so first day at my new school, I used my phone to upload a video outside the school. Phones these days are powerful, all the data on the mainframe system we found you on? Smaller than my screensaver. So, I took a video and uploaded the file. By the time I got close enough to reach the doors? Someone found me, she'd already watched the video. Five times, apparently. I mean, I knew my vlog had some viewers but... Right, not the point. Anyway, upload and download speeds are just that fast these days."
