• 32-bit word:  VAX computers and personal computers of the IBM PC type, the byte order is 1,2,3,4 with the least significant byte written first. In Hewlett Packard, Macintosh and Sun computers, the byte order is 4,3,2,1 meaning that the least significant byte is written

last. In PDP-11 computers the byte order is 3,4,1,2 meaning that in the two 16-bit words comprising a 32-bit word, the most significant 16-bit word is written first. Within the 16-bit word, however, the least significant byte is written first, which is the same as for a PC.
