One Gigabyte (1 GB) means 109 = 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
1 GB = 230 = 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.
