24 What are the memory capabilities of the 32 bit and 64 bit CPU architectures?

The primary difference in memory capabilities between 32-bit and 64-bit CPU architectures lies in the amount of addressable memory. A 32-bit architecture can theoretically address up to 4 GB of RAM (2^32 bytes), while a 64-bit architecture can address significantly more, up to 16 exabytes (2^64 bytes), although practical limits are lower due to operating system constraints. This increased addressable memory in 64-bit systems allows for better performance in applications requiring large amounts of RAM, such as databases and high-performance computing tasks. Consequently, 64-bit systems can handle more applications simultaneously and manage larger datasets more efficiently.
