Explanation
A 32-bit operating system uses 32-bit memory addresses. The maximum number of unique addresses is 2³² = 4,294,967,296 bytes, which equals exactly 4 GB. Windows 32-bit editions (x86) enforce this ceiling regardless of how much physical RAM is installed; the OS simply cannot address memory beyond that boundary. 64-bit editions remove this limitation and support terabytes of RAM depending on the specific edition.
