The ordering of the bytes of a multi-byte value in addressed memory. Little-endian storage puts the least significant byte at the lowest address; big-endian storage puts the most significant byte there. Logical shifts of a value already held in a processor register act on bit significance, independently of that storage convention.

Endianness refers to the order in which bytes are arranged within larger data types (such as integers or floating-point numbers) when stored in computer memory. It plays a crucial role in data interpretation and communication between different systems and architectures. There are two primary types of endianness: 1. **Big-endian**: In this format, the most significant byte (the "big end") is stored at the lowest memory address, while the least significant byte is stored at the highest address.
