Can any body tell me how search engine ( specially Google ) calculate page rank of a particle page....
Their exact algorithm for page rank is a secret however they have said that things such as keyword density, title keywords, age of site, sites linking in, and the content you have on your page plays a significant role in how Google ranks you.
^^^ good info. I have always wondered this as well. If you site is linked on sites with high PR your own PR will go up as well. There is some chart that explains this.
