SUBJECT: BIO's vs. DIO's

Hello,

     I understand the glossary definitions of Direct and Buffered I/O's,
but what do they mean in real life?  We are trying to set up a system of
monetary rates here, but we don't really understand what generates a DIO
and what generates a BIO.  Could anybody explain what these counts REALLY
mean, as far as actual operations are concerned?  Thanks in advance,
