least significant bit

[¦lēst sig¦nif·i·kənt ′bit]
(computer science)
The bit that carries the lowest value or weight in binary notation for a numeral; for example, when 13 is represented by binary 1101, the 1 at the right is the least significant bit. Abbreviated LSB.

least significant bit

(data)
(LSB) Bit zero, the bit of a binary number giving the number of ones, the last or rightmost bit when the number is written in the usual way.
