Definition

The least significant bit (LSB) is the bit in a binary number that represents the smallest value. Since binary numbers are widespread in computing and related fields, even the LSB significantly impacts binary data transmission.

In binary computation, the rightmost number is the least significant digit, while the leftmost is the most significant bit. Positional notations place the least significant bit in this position.

When transmitting binary data, the LSB is sent first using the LSB first technique, followed by the subsequent bits in increasing significance. Hash functions and checksums usually use the least significant bit.
