Processor architecture
  1. x86
    1. A 32-bit architecture that processes multiple instructions using a 32-bit address space.
      1. An x86 processor uses fewer registers than an x64 processor.
        1. Registers are storage areas used by the CPU when performing calculations.
          1. An x86 processor can support a 32-bit operating system.
          2. x64
            1. This 64-bit architecture adds additional registers specifically for instructions that use a 64-bit address space.
              1. The additional registers allow the CPU to process instructions much faster than x86.
                1. The x64 processor is backward compatible with the x86 processor.
                  1. An x64 processor can support 32-bit and 64-bit operating systems.
