Meaning – The word exabit, refers to a subunit of the standard storage unit (bit) of computer storage or digital information. Mathematically speaking, the prefix exa (symbol E) is defined in the International System of Units (SI) as a multiplier of 10^18 (1 quintillion, short scale), and therefore
1 exabit = 10^18 bits = 1000000000000000000 bits
The Exabit has a unit symbol Eb.
TThe unit exabit is also said to be related to the exbibit, a unit that is derived from the binary prefix exbi of the same order of magnitude, which is equal to 2 ^ 60 bits = 1152921504606846976bits, or approximately 15% larger than the exabit.
Example of usage – “When she was studying the concepts of computer storage and digital information, she came across the unit exabit, something she had not heard of before.”
