A 128-bit register can store 2 128th (over 3.40 × 10 38th) different values. The range of integer values that can be stored in 128 bits depends on the integer representation used.
a general rule for binary is that the number of alternatives = 2 raised to the # of bits power. Two to the seventh power is 128
With 4 bits, you can represent 2^4 or 16 different numbers. This is because each bit can have 2 possible values (0 or 1), so with 4 bits you have 2 x 2 x 2 x 2 = 16 possible combinations. These numbers range from 0 to 15 in decimal representation.
Binary bits are necessary to represent 748 different numbers in the sense that binary bits are represented in digital wave form. Binary bits also have an exponent of one.
