Synonyms

Morphology
The meaning 'a bit added to detect errors' is directly derivable from combining 'check' (to verify or test) with 'bit' (a binary information unit): it denotes a bit used for checking. This is a straightforward technical compound following normal English composition patterns, so a B1 learner who knows both constituents would readily infer the function of a 'check bit'.
Etymology
Check bit comes from the simple idea of adding one small extra bit that checks a group of bits by making the total number of 1s 'even', so a mistake will stand out. That's why a check bit helps find errors in data.
