One Terabyte (1TB) = 1,000 Gigabytes (GB). One Gigabyte (1GB) means 10
9
= 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.
