# Off The Wall: How Many Combinations?

How big is 64 K, really? Have you ever wondered exactly how many possible combinations there are in 65536 memory locations, each capable of assuming values from 0 to 255? Well, 64K bytes is 524288 bits, so the number of possibilities is 2**524288, or about 2.6E157826 (26 followed by 524,287 zeros). Printing this number in decimal would take 225 screens on your computer display.
