Overview
This article summarizes the differences between Little Endian and Big Endian.
What is Endian?
- The method of arranging multiple bytes is called Endian or byte order.
- It refers to how data is arranged when loaded into memory.
- Endian is determined by the CPU, protocol, and OS.
- Problems related to Endian can easily arise when exchanging data between different systems or networks.
- e.g. Endian conversion is necessary when analyzing binaries.
Big Endian
- A method where data is arranged from the lower address in the order of higher bytes to lower bytes.
- e.g. Hexadecimal 00 01 02 03 → 00 01 02 03
Little Endian
- A method where data is arranged from the higher address in the order of higher bytes to lower bytes.
- e.g. Hexadecimal 00 01 02 03 → 03 02 01 00
Middle Endian
- A more irregular method than the above two.
Bi-endian
- A method that switches between Big Endian and Little Endian.
