What is Gigabyte?

Gigabyte is a digital storage unit used to express file size, memory or device capacity.

Short history of Gigabyte

It uses a decimal SI prefix (kilo = 1,000, mega = 1,000,000). Storage makers and network speeds use these decimal values, while some operating systems report sizes in binary units (KiB, MiB), which is why a drive can look smaller than its label.
