32 bit vs. 64 bit:The two main classes of processorsCPU are 32 bit and 64 bit. The kind of a CPU changes the ordinary efficiency of a pc and it also determines what kind of application is used. For example, a computer with a 32 bit CPU cannot have a 64 bit version of an put in operating systemOS.
On any other hand, a pc with a 64 bit CPU can have the both types of OS but with a 32 bit OS, it cannot reach the maximum performance. A CPU register stores memory addresses, which is how the CPU accesses data from RAMphysical memory. Therefore a 64 bit CPU can do more calculations per second, so it provides much more speed and effectivity.
