The Byte Chain (1.3.1, 4)

Knuth asks:

A kilobyte (kB or KB) is 1000 bytes, and a megabyte (MB) is 1000 kB. What are the official names and abbreviations for larger numbers of bytes?

Thanks to wikipedia we have

1000 MB = 1 gigabyte (GB)
1000 GB = 1 terabyte (TB)
1000 TB = 1 petabyte (PB)
1000 PB = 1 exabyte (EB)
1000 EB = 1 zetabyte (ZB)
1000 ZB = 1 yottabyte (EB)
