What is a string of 8 bits called?

Why is MSB and LSB important?

In a binary number, the bit furthest to the left is called the most significant bit (msb) and the bit furthest to the right is called the least significant bit (lsb). The MSB gives the sign of the number (sign bit) , 0 for positive and 1 for negative. The remaining bits hold the magnitude of the number.

## Can MSB or LSB first?

As with bits, the MSB (byte) is normally the byte farthest to the left, or the byte transmitted first in a sequence. When the MSB in a sequence is farthest to the left (or first), the least significant bit or byte (LSB) is usually the one farthest to the right (or last).
