Least significant bit

Sometimes abbreviated as LSB, the least significant bit is the lowest bit in binary numbers. It is either the leftmost or rightmost bit in a binary number, depending on the computer's architecture. If the LSB is on the right, the architecture is called "little-endian." If the LSB is on the left, the architecture is called "big-endian."

For example, in a little-endian architecture, the LSB of binary number 00000001 is 1, as it is the rightmost bit.
