Why each option
A 32-bit processor can address a maximum of 4 gigabytes (GB) of memory.
1GB is well within the 32-bit addressing limit but is not the maximum supported amount.
2GB is well within the 32-bit addressing limit but is not the maximum supported amount.
A 32-bit processor uses 32 bits to address memory, which means it can access 2^32 unique memory locations. Since each location addresses 1 byte, this calculates to 4,294,967,296 bytes, or exactly 4 GB of RAM.
8GB of memory requires a 64-bit processor architecture because 32 bits are insufficient to address that much RAM.
