# Most significant bit or byte

The most significant byte (MSB) is the byte that contains the most significant bit (MSB) in a multi-byte number. In a two's complement number, the MSB is the sign bit. In a big-endian system, the MSB is the byte at the lowest memory address. In a little-endian system, the MSB is the byte at the highest memory address.

### What is LSB and MSB examples?

The least significant bit (LSB) is the bit position in a binary number having the least value. The LSB is sometimes referred to as the "right-most" bit, due to the convention in positional notation of writing less significant digits to the right. For example, the decimal number 12 can be represented as:

The most significant bit (MSB) is the bit position in a binary number having the greatest value. The MSB is sometimes referred to as the " left-most" bit, due to the convention in positional notation of writing more significant digits to the left. For example, the decimal number 12 can be represented as:

MSB
LSB

0

0
1

1

The value of the MSB depends on the number of bits used to represent the number. For example, if we use 4 bits to represent the number 12, then the MSB will be 1:

MSB
LSB

0
0

0
1

1
0

1
1

If we use 8 bits to represent the number 12, then the MSB will be 0:

##### What is the least significant byte?

The least significant byte (LSB) is the byte that represents the smallest value in a word. In a two's complement system, the LSB is the "1" bit. In a system using sign and magnitude representation, the LSB is the "0" bit. In a system using excess-3 representation, the LSB is the "3" bit.

What are least and most significant digits? Least significant digits are digits that carry the least weight or importance in a number. In our number system, the least significant digit is the digit in the ones place. Most significant digits are digits that carry the most weight or importance in a number. In our number system, the most significant digit is the digit in the tens place. What is bit significance? The bit significance of a digital signal is the number of bits used to represent the signal. For example, the digital signal from a microphone may be represented by a 16-bit word. How do you calculate MSB and LSB? MSB stands for Most Significant Bit and LSB stands for Least Significant Bit. To calculate MSB, take the binary number and divide it by 2 until you get a number less than 1. The number of times you divide by 2 is the MSB. To calculate LSB, take the binary number and divide it by 2 until you get a number less than 1. The number of times you divide by 2 is the LSB.
