A gigabyte is a measure of storage on a computer memory chip, a peripheral device such as a hard drive or flash drive, or the media used in these drives such as CD and DVD optical discs. One gigabyte, abbreviated GB, is equal to one billion bytes. Apple's iPhone 4 can be purchased with 16 or 32 gigabytes of on-board memory for storing multimedia files such as music, videos and voice mail as well as applications. You can view the amount of gigabytes on your iPhone and find out how much of this memory is available to you for storage through the iPhone's "Settings" menu.
