Endianness refers to the order in which bytes are arranged in multi-byte data types.

Most Significant Byte (MSB) is stored first. Used in network protocols and some processors like Motorola.

Example: 0x12345678 → [12] [34] [56] [78]

Least Significant Byte (LSB) is stored first. Used in x86/x64 processors and many embedded systems.

Example: 0x12345678 → [78] [56] [34] [12]
