Detailed explanation-1: -One gigabyte (GB) is about 1 billion bytes, or 1 thousand megabytes. A computer might have 4 GB of RAM. A flash memory card used in a camera might store 16 GB. A DVD movie is roughly 4-8 GB.
Detailed explanation-2: -A gigabyte (GB)–pronounced with two hard Gs–is a unit of data storage capacity that is roughly equivalent to 1 billion bytes. In decimal notation (base 10), a gigabyte is exactly 1 billion bytes. In binary notation (base 2), a gigabyte is equal to 230 bytes, or 1, 073, 741, 824 bytes.
Detailed explanation-3: -A kilobyte (KB) is 1, 024 bytes, not one thousand bytes as might be expected, because computers use binary (base two) math, instead of a decimal (base ten) system. Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB).
Detailed explanation-4: -An extraordinarily large unit of digital data, one Exabyte (EB) is equal to 1, 000 Petabytes or one billion gigabytes (GB).
