  • Memory is addressed by the byte
    • Might be numbered first to last
    • Least significant bit to Most significant bit or vice versa
    • Computer designs need only be internally consistent in byte ordering
  • Byte order is important when sending information between computers, they have to know the order of the bytes to be able to interpret them
  • Little Endian vs Big Endian ordering
  • In Little Endian ordering, the least significant bit comes first. The “Little” byte is placed in the lowest memory address followed by rest from LSB -> MSB
  • In Big Endian ordering, the most significant bit/byte comes first, it goes in the lowest memory location. The remaining bytes take up the rest of the lcoations.
