Powers of two are often used to define units in which to quantify computer memory sizes. A "byte" now typically refers to eight bits (an octet), resulting in the possibility of 256 values (2 8).

Apr 8, 2019 · 2^256 is pronounced “two to the power of two hundred and fifty six”. What does it represent? Computers represent numbers in binary. Here is an example where we have 2 bits, where each bit can represent a ‘1’ or a ‘0’ allowing us to produce 4 possible combinations: The formula “2^number of bits” gives us the range of numbers that we can represent.
