I'm really confused which operating system 32-bit or 64-bit is for x86 and for x64????. I have searched on web and someone said x86 is for OS 32-bit and x64 is for OS 64-bit. Is that right??? This is really confusing. If anyone doesn't mind to tell me why it is called x86 and x64, I really appreciate it 

. Thank you and appreciate in advance
