What is a Gigabyte?
The gigabyte equals 1,024 megabytes (1,073,741,824 bytes) in binary conventions, or one billion bytes in decimal SI conventions. It is the principal unit for consumer storage: smartphones, USB drives, and most hard drives are sized in gigabytes or terabytes. A full-length HD movie in compressed format requires about 4–8 GB. The discrepancy between binary and decimal definitions means a '1 GB' drive shows as about 0.93 GB in Windows.
