Intel PAE if the answer, but it still came with other issues, so 64 was still the better answer.
Also the entire article comes down to simple math.
Bits is the number of digits.
So like a 4 digit number maxes out at 9999 but an 8 digit number maxes out at 99 999 999
So when you double the number of digits, the max size available is exponential. 10^4 bigger in this case. It just sounds small because you’re showing that the exponent doubles.
10^4 is WAY smaller than 10^8
