It's the old question: is a "megabyte" 2^20 bytes or 10^6 bytes? Marketers like base 10 because they can report bigger megabyte counts on their hard drives, but many engineers still see everything in base 2. Hard drives, even in sizes greater than 100G, are still measured in megabytes. So a drive with 1200 base-10 megabytes (120G) only counts as 1144 base-2 megabytes (114G). (1200*(10^6))/(2^20) = 1144 The disparity is even wider if you do battle at the next level up: is a gigabyte 2^30 or 10^9? In that case, the 120G HD is only 111G: (120*(10^9))/(2^30) = 111 Reminds me of Tom Lehrer's semi-classic "New Math": Now, that actually is not the answer that I had in mind, because the book that I got this problem out of wants you to do it in base eight. But don't panic! Base eight is just like base ten really - if you're missing two fingers! Shall we have a go at it?
