Endianness

Dictates which orders bytes are written and read (e.g. in memory). Can apply to processors, or formats, etc

• Little endian is least-significant byte first
  • E.g. x86 and x64
• Big endian is most-significant byte first
  • e.g. RISC
• Some formats can be either-endian (e.g. UTF-8 has a Byte Order Mark)
• Some systems can work in either-endian
  • ARM can configure endianness
