Web12 feb. 2024 · 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. Bit position n has the value of 2^ n, so, for instance, the number 1010 (unsigned) will be equal to 2^3 + 2^1 = 8 + 1 = 9. In this instance, the rightmost bit is the LSB and the leftmost bit the MSB.
