" Your hard drive is advertised as having a 60GB capacity, but your computer shows only 55.8GB. What gives? The discrepancy is the result of having two methods of measuring memory. Computers are binary, or &amp;quot;base two,&amp;quot; mathematical systems, and in a binary world a kilobyte is 1024 bytes (2 to the 10th power). When computers were new, the geekerati referred to this as a &amp;quot;kilo.&amp;quot; Noncomputer folks, however, understood kilo to mean thousand, and thought that 1000 bytes should equal a kilobyte. So, two different measurements of hard drive space were born. In 1998, the International Electrotechnical Commission (IEC) weighed in, defining 1 &amp;quot;gigabyte&amp;quot; as 1 billion bytes. Hard disk manufacturers agree, marketing their products using the rounder decimal value instead of the binary system. So, your drive is labeled as decimal (&amp;quot;giga&amp;quot;) and your PC reads binary (IEC&amp;#039;s term, &amp;quot;gibi&amp;quot;). Either way, you&amp;#039;re getting the same bunch of bytes.
