And 1 KB is 1,024 bytes. So a 320GB hard drive has 320,000,000,000 bytes (or so). To your computer's operating system, a GB is 2^30 bytes (1,073741824). So it will report as about 298GB. I'm not sure if that answers your question, but your question isn't precise enough to answer completely.

As you can see, to the left, eukaryotic cells are typically larger than prokaryotic cells.
