 The binary representation of decimal 149, with the lsb highlighted. The msb in an 8-bit binary number represents a value of 128 decimal. The lsb represents a value of 1. In computing, the least significant bit (lsb) is the bit position in a binary integer giving the units value, that is, determining whether the number is even or odd. The lsb is sometimes referred to as the right-most bit, due to the convention in positional notation of writing less significant digits further to the right. It is analogous to the least significant digit of a decimal integer, which is the digit in the ones (right-most) position.

The binary numeral system (base 2 numerals) represents numeric values using two symbols, typically 0 and 1. ...
Originally, the word computing was synonymous with counting and calculating, and a science that deals with the original sense of computing mathematical calculations. ...

The binary numeral system (base 2 numerals) represents numeric values using two symbols, typically 0 and 1. ...
The integers consist of the positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero. ...
Positional notation is a system in which each position has a value represented by a unique symbol or character. ...
In mathematics and computer science, a numerical digit is a symbol, e. ...
The decimal (base ten or occasionally denary) numeral system has ten as its base. ...
In referencing specific bits within a binary number, each bit is assigned a bit number, ranging from zero to n (depending on the number of bits in the number.) The phrase bit zero may refer to either the lsb or the most significant bit (msb), depending on the bit-numbering endianness. The binary representation of decimal 149, with the MSB highlighted. ...
Endianness generally refers to sequencing methods used in a one-dimensional system (such as writing or computer memory). ...
By extension, the least significant bits (plural) are the bits of the number closest to, and including, the lsb.
The least significant bits have the useful property of changing rapidly if the number changes even slightly. For example, if 1 (binary 00000001) is added to 3 (binary 00000011), the result will be 4 (binary 00000100) and three of the least significant bits will change (011 to 100). By contrast, the three most significant bits stay unchanged (000 to 000).
Least significant bits are frequently employed in pseudorandom number generators, hash functions and checksums. A pseudorandom number generator (PRNG) is an algorithm that generates a sequence of numbers, the elements of which are approximately independent of each other. ...
A hash function or hash algorithm is a function for examining the input data and producing an output hash value. ...
A checksum is a form of redundancy check, a very simple measure for protecting the integrity of data by detecting errors in data that is sent through space (telecommunications) or time (storage). ...
LSB, in all capitals, can also stand for "least significant byte". The meaning is parallel to the above: it is the byte in that position of a multi-byte number which has the least potential value.
