- I don't know what they are teaching CS people these days, but one KB of RAM
- has always been 1024 bytes which corresponds to the number of address
- lines. Also, by the same reasoning, 1 MByte, is 1024 x 1024. Now, the
- question is: do disk manufacturers follow this convention or do they use
- the Mega = 10^6 value? If they do, it is another marketing ploy to use
- the largest number they can get away with (similar to unformatted disk
- capacity).

- ps Maybe the different convention determines whether you are hardware or
- software oriented.
