WebApr 8, 2016 · Bits aren't given numeric positions. Instead we speak of the least significant bit (LSB) and the most significant bit. Unfortunately, in general things aren't that simple. The generalization of the LSB is the "lower 8 bits" or the "lower 4 bits", and you might speak of e.g. the 3rd-lowest bit. Insofar, terminology is definitely 1-based. In computing, the least significant bit (LSb) is the bit position in a binary integer representing the binary 1s place of the integer. Similarly, the most significant bit (MSb) represents the highest-order place of the binary integer. The LSb is sometimes referred to as the low-order bit or right-most bit, due to the convention in positional notation of writing less significant digits further to the ri…
