– There are two ways that byte addresses can be assigned across words.

→ computer store data in Memory 

→Formating at the byte level of the data which is called endianness which refer to ordering of bytes.

→The name big-endian is used when lower byte addresses are used for the more Significant bytes (Left most)

→The little-endian is used for the opposite ordering where lower byte address are used for the less significant bytes (Right most)

Endianness refers to the way bytes are ordered when a data item with a site bigger than 1 Byte is placed in memory / transferred over a communication interface.

Two type of endianness:-

  1. Little endian- The bytes are ordered with the LSB placed at the low and address. 
  2. Big endian- The bytes are ordered with the MSB placed at the lowest address.
