When is it useful past the point of just looking it up as need be?
It's not something you try to recite. You just do it so many times you became too good at it to look at the table.
Four bits can represent up to 15, from 0000 to 1111. Correspondingly, 0 to F in hex.
Binary from right to left is 1, 2, 4, 8.
One byte is eight bits. It takes eight digit places.
XXXX XXXX
0000 0000 to 1111 1111
00 to FF
0 to 255
I mean when would it be so necessary that it jystifies itself or the time cost to do so
It's useful if you're a network engineer or a web designer.
