File:Byte Order (Endianness)

This computer science lesson explains what is meant by byte order, also known as endianness. It covers the difference between storing data in memory, or files, either in big-endian format or little-endian format. The historical advantages of each byte order are discussed, but the video also explains why both byte orders are equally as good with today’s computers. The endianness used when transmitting data on computer networks, that is Network byte order (big endian), is also described.
