Can you solve the burning stick riddle? ft Simone Giertz part 3/3

First off, just subscribed to the channel, love the videos, a smart, funny and bubbly woman showing cool physics things is definitely up my alley.
But I have to ask Diana, how did you not instantly know bit vs byte? I thought you were working as a programmer? Granted, it's usually just ints everywhere (not even specifically 32 bit ones but ints dependent on the underlying architecture the code is compiled for), but still there's the occasional necessity for bytes (bits are always in use, but they're most often called bools so fair enough on not connecting that dot) which also equate to 256 bits (0-255) which, for example, constitutes colours; usually you have an (a)rgb definition of a colour with the channels of it in separate byte variables.
I'm not slagging or something, I'm just curious how this is not something you instantly recognise?
