What is pagerank?

confused on its meaning

[Andrew Thomas]

I hear about page rank, i have a page rank of 3 out of 10, how does page rank work, is it calculated on the number of hits recieved through google, and whats the best way of increasing my pagerank?

Also is pagerank on a single page or my entire website?

thanx
