A 64-bitWindows 7 Professional computer can theoretically handle how much memory?
  1. 4 GB of RAM
  2. 192 GB of RAM
  3. 8 GB of RAM
  4. 512 GB of RAM
Explanation
Answer: B - A 64-bitWindows 7 Professional computer can theoretically handle 192 GB of RAM. However, it is unlikely that you would install that much memory.

Key Takeaway:In theory, 64-bit computers can support up to 16 exabytes of RAM, but a physical limit of 4 petabytes has been imposed due to size limitations on physical memory chips. Also, operating systems impose further limitations on the amount of memory they can address.
