Detailed explanation-1: -In principle, a 64-bit microprocessor can address 16 EiB (16 × 10246 = 264 = 18, 446, 744, 073, 709, 551, 616 bytes, or about 18.4 exabytes) of memory.
Detailed explanation-2: -A 64-bit processor can actually process much more than twice the data that a 32-bit processor can handle. In fact, a 64-bit processor can theoretically process up to 18, 446, 744, 073, 709, 551, 616 bytes, or 16 exabytes (EB) at one time.
Detailed explanation-3: -One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4 gigabytes (4, 294, 967, 296 bytes) of RAM. The actual limit is often less – around 3.5 gigabytes – since part of the registry is used to store other temporary values besides memory addresses.
