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. WebAug 6, 2014 · Solution 1. Simple: one can contain negative values, the other can't. To expand a little, a signed value uses one bit (usually the top, or most significant bit) to indicate if the number is positive or negative, and an unsigned integer uses all available bits for the number - so the number of different values that can be held is the same, but ... marketing mix of a company
