About These Units
About Gigabyte (GB)
The Gigabyte is a unit of information storage equal to 1024 megabytes in binary terms, or approximately one billion bytes in decimal terms. It's commonly used to measure computer memory, storage capacity, and data transfer rates.
About Megabyte (MB)
The Megabyte is a unit of information. It is very common in the computer world, but it is poorly defined. Often it means 1 000 000 bytes, but sometimes it means 220 = 1 048 576 bytes. As if that werent confusing enough, the 1.44 megabytes stored on "high density" floppy disks are actually megabytes of 1 024 000 bytes each. This uncertainty is a major reason for the recent decision of the International Electrotechnical Commission to establish new binary prefixes for computer science.
