- This is one of my peeves. Most people, even educated, computer-literate types,
- don't distinguish between 1000 and 1024. Few people seem to realize that,
- although the difference is small for values up to the hundreds of K, when you
- are dealing with megabytes and gigabytes they really diverge quite a bit.
-
- In practice, as when calculating transfer rates or repartitioning a disk, I'm
- careful to calculate in terms of true K, M, and G, but when someone asks me how
- big a file is or how much space is left on a partition, I'm sloppier and
- sometimes use K as an abbreviation for "thousand", etc.
-
- Bottom line: if it matters, make sure it's clear which meaning is being used.
