The exabit is a multiple of the unit bit for digital information or computer storage. The prefix exa (symbol E) is defined in the International System of Units (SI) as a multiplier of 1018 (1 quintillion, short scale), and therefore 1 exabit = 1018 bits = 1 000 000 000 000 000 000 bits = 1000 petabits. The exabit has the unit symbol Ebit or Eb.
The mebibyte is a multiple of the unit byte for digital information. The binary prefix mebi means 220, therefore one mebibyte is equal to 1048576bytes = 1024 kibibytes. The unit symbol for the mebibyte is MiB. Technically a megabyte (MB) is a power of ten, while a mebibyte (MiB) is a power of two, appropriate for binary machines.
