How to Tell If My Computer Is 32 or 64 Bit?

A 32-bit computer and 64-bit computer process information differently. A 32-bit computer processes information less efficiently than a 64-bit computer. It’s important to know which type your computer is simply because device drivers that run on a 64-bit system will not work at all on a 32-bit system and device drivers built for a 32-bit system will not run on a 64-bit system. Finding out what your computer is only a matter of completing a few steps.
