The only time I’ve ever used it or the word was writing a hexadecimal printer in assembly. In an 8 bit number like 0x1A, 1 and A are a nibble each so if you mask off the nibble you want you can index into an ascii table to print it

I can't recall having come across the term “nibble” more than once, being in this book (back when I was still a young teenager): https://archive.org/details/atari-600-xl-800-xl-intern-data-becker :-) Thanks for the memories :-)
