<Note for storage capacity calculations>
 Memory capacities and requirements, file sizes and storage requirements, etc. must be
calculated according to the formula 2
n
. The following examples show the results of such
calculations by 2
n
(to the right of the equals signs).
1 KB (kilobyte) = 1,024 bytes
1 MB (megabyte) = 1,048,576 bytes
1 GB (gigabyte) = 1,073,741,824 bytes
1 TB (terabyte) = 1,099,511,627,776 bytes
 Disk capacities, however, must be calculated using the formula 10
n
. Listed below are the results
of calculating the above example capacities using 10
n
in place of 2
n
.
1 KB (kilobyte) = 1,000 bytes
1 MB (megabyte) = 1,000
