I was going through mails and in one mail a person asked me, what is this 32 bit and 64 bit things and how do I know if my system is 32 bit or 64 bit. Which application my system would support and so on…So, I thought better to document one small article which will answer those questions with minimal essential explanation of the terms involved using simpler way. I googled and collected few important paragraphs from various tech sites and posting it at one place.
