I was reading about Virtual Memory and I came to know that it serves as a backup memory for the Main Memory. I am failing to understand the advantage. Why would you make a backup from a memory location which would be accessed if the item is not found in the Main Memory. Please help me clear out the concept.

Virtual Memory is not really backup of your RAM memory, it is more like addition RAM memory in that it copies RAM memory to the page file so the active programs can have the use of the RAM memory. This page has good short explanation of Virtual Memory http://www.howstuffworks.com/virtual-memory.htm | |||
