WebFeb 12, 2024 · Definition: The least significant bit (LSB) is the bit position that has the least value associated, that is, the value of 1. Let's say we have a 32-bit machine that deals with 32-bit words. Each word is a string of four octets (bytes), so there are 32 bits in it. Then, generally, bit position 0 is the LSB, and bit position 31 is the MSB. Web2 Answers. It doesn't.
