Endian

The endianess defines the way data is stored in physical memmory.

There are two standards:

• Little endian
• Big endian

Both are well-widely used and common.

Little endian requires the bytes with the numbers with lower weight to be placed first in memory.

Big endian requires the bytes with the numbers with higher weight to be placed first in memory.

Other endianness exist (such as middle-endian) but are mostly very old, outdated and non-standard.
