Endianness describes the order bytes are stored in memory in a multi-byte piece of data.
For example, the 2-byte(16-bit) integer 27591 is stored differently in big endian(BE) and little endian(LE).
# left-to-right
BE: 01101011 11000111 # 0110101111000111

Terminology
background: If a large integer is stored in memory, it will require multiple bytes (8-bits).
For example, the number 4095 requires 12 bits.
In binary this would be0000111111111111.
If described in 2x 8-bit bytes, this would be00001111 11111111.terminology
most significant byte: | byte containing the highest chunk of the number. ex: 9876..... in 987654321 least significant byte: | byte containing the lowest chunk of the number. ex: ....54321 in 987654321
