IPA: /ˈsʌbˌblɒk/
KK: /sʌbblɑk/
A smaller section or part of a larger block, often used in data organization or construction.
The software divides the data into several subblocks for easier processing.
Subblock → It is formed from "sub-" (meaning under or below) and "block" (from Old French *bloc*, meaning a solid piece of material). The word "subblock" refers to a block that is situated under or below another block.
Think of something that is 'under' ('sub-') another 'block' — that's why a subblock is a block located beneath another.
