 = 1,000,000,000 bytes using powers of 10.  A computer 
operating system, however, reports storage capacity using powers of 2 for the definition of 
1GB = 2
30
 = 1,073,741,824 bytes, and therefore shows less storage capacity.  Available storage 
capacity will also be less if the computer includes one or more pre-installed operating systems, 
pre-installed software applications, or media content.  Actual formatted capacity may vary.
