Hello friends I am using my computer system form last one year and still dont know whether my processor is a 32 bit or a 64bit. I know this is really stupid question to be asked but I really want to know how can I be able to know which processor am I using. Is there any software to know about it or it is that there this is written some where in the internal hardware of the CPU. So can one help me to know about this. I would be thankful to any one who comes up with the solution.
