How will you know if you are using a 32-bit or 64-bit PC? What are the differences between the two? I'm sure most Windows PC users didn't even know about it.
Have you ever experienced trying to download a software that requires you to choose between 32-bit and 64-bit and you didn't know what to choose because you have no idea about the system type of your computer? That is one of the reasons why you should know about it.
