LIMOR said “ computersword on ones & zeroes but actully today almost nobody deals directly with ones & zeroes but ones & zeroes do play a big role in How computer work if we have a single can either be on or off thatsa lot of choices but it’s raelly important start with one wire we can represent a yes or no true or false or 1 or 0 .”
