...2 20 (1 048 576) rather than 10 6 (1 000 000). However, there is a variation in usage depending on the context. In discussing memory capacities megabyte generally means 2 20 bytes, but in disk storage (and data transmission) megabyte is often taken to mean 10 6 bytes. (In some contexts, as in the capacity of a floppy disk, it has even been quoted as 1 024 000 bytes, i.e. 1000 times a (binary) kilobyte.) The IEC attempted to resolve this confusion by introducing binary prefixes, modelled on the normal decimal prefixes, as follows: kibi- 2 10 mebi- 2 20...
