- 650 to 700 Megabytes - A CD-ROM
Gigabyte
Gigabyte (2^30 = 1.073.741.824 Bytes ca. 10^9 Bytes)
- 5 GB - A compressed movie
Terabyte
Terabyte (2^40 = 1.099.511.627.776 Bytes ca. 10^12 Bytes)
- 20 TB - The text size of the collection of the Library of Congress with about 20 million books (1963 - should now be up to 80 TB)
