WebEndianness can be either big or small, with the adjectives referring to which value is stored first. Big-endian is an order in which the "big end" (most significant value in the sequence) is stored first, at the lowest storage address. Little-endian is an order in which the "little end" (least significant value in the sequence) is stored first. WebMar 3, 2011 · @Marisha Note the historical ordering: 1) Arabic numerals invented, little-endian; 2) European cultures copy-paste Arabic number and math notation without adjusting for opposite written language direction, causing endian-flip; 3) modern American culture derives from European culture, including the big-endian number notation; 4) …

WebBig/little endian is of course also implementation-defined. This means that your struct could be allocated in the following ways (assuming 16 bit ints): PADDING : 8 f1 : 1 f2 : 3 f3 : 4 or PADDING : 8 f3 : 4 f2 : 3 f1 : 1 or f1 : 1 f2 : 3 f3 : 4 PADDING : 8 or f3 : 4 f2 : 3 f1 : 1 PADDING : 8 Which one applies?

Each group is assigned a number, called its address, that the computer uses to access that data. On most modern computers, the smallest data group with an address is eight bits long and is called a byte. Larger groups comprise two or more bytes, for example, a 32-bit word contains four bytes.
