The animals went in two by two, the elephant and the kangaroo. . .. It was a binary parade of sorts that went into Noah's ark "for to get out of the rain" - the critters were represented in pairs. If you recall those partnered beasts, you'll remember the etymology of binary, because it traces to the Latin bini, which translates as "two by two." Although "binary" can be used for anything with two parts, it is now used especially in relation to computers and information processing. Digital computers use the binary number system, which includes only the digits 0 and 1, to process even complex data. In binary form, for instance, the word HELLO looks like this: 1001000 1000101 1001100 1001100 1001111.
