32-bit machine:Typically, a 32-bit CPU means that the cup can compute 32 bits at a time. 64-bit machine:Typically, a 64-bit CPU means that the CPU can compute 64 bits at a time. 32-bit operating system:made for 32-bit machines. Refers to the operating system's word length is 32-bit, but also indirectly affect the address bus, therefore, the maximum address space
