According to Microsoft’s definition, 32-bit and 64-bit refer to the way a computer’ processor (also known as CPU) handles information.

The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system (32-bit processor supports 3-4GB while 64-bit supports over 4GB). The Operating System and software on a computer is also determined by its processor.

A computer with a 64-bit processor can have a 64-bit or 32-bit version of operating system and software installed. However, 32-bit computer can only accept 32-bit operating system and application.
