Orders of magnitude of data. The yottabyte is a multiple of the unit byte for digital information. The prefix yotta indicates multiplication by the eighth power of 1000 or 1024 in the International System of Units (SI), and therefore one yottabyte is one septillion (one long scale quadrillion) bytes. The unit symbol for the yottabyte is YB.
A kilobyte equals 1000 bytes (actually 1024 bytes but we normally round it off). A megabyte equals 1,000,000 bytes. A gigabyte equals one billion bytes. For comparison, a standard 3 1/2 inch floppy disk holds 1.44 megabytes (1,440,000 bytes). A Zip disk holds 100 or 250 megabytes.
