Why each option
This question asks about the theoretical maximum addressable memory space for a 64-bit processor, which impacts the maximum addressable hard drive space.
16TB is significantly less than what a 64-bit processor can theoretically address, as 16TB is 2^44 bytes, not 2^64 bytes.
64TB is also significantly less than the 16EB theoretical limit for a 64-bit architecture and is not the correct calculation for 2^64 bytes.
A 64-bit processor can theoretically address 2^64 bytes of memory, which calculates to approximately 18.4 quintillion bytes. This value is approximately 16 exabytes (EB), where 1 EB equals 1024 petabytes (PB) or 2^60 bytes, representing the maximum addressable space for both RAM and storage.
64EB is incorrect because 2^64 bytes equates to approximately 16 EB, not 64 EB.
