  • "Array" conveys a sense of homogeneity (and often arbitrary length), i.e. where all the bits mean the same and are distinguished only by their index. A bit mask/map may be heterogeneous and contain individual flags with different denotation. Commented May 5 at 21:50
  • @Bergi, it is of homogenous data type (i.e. bits), and the length could be varying (i.e. there could be unused bits within the overall fixed-length field allocated). I would associate the "mask" with the value used to modify the effect of the bitwise operators, not with the main field being operated upon. Commented May 5 at 22:17
  • I agree, I'm just not certain that the OP made this distinction Commented May 5 at 22:21
