Hi Vijay,

Sorry for omitting this one.

It is absolute:
A leecher is a peer that is downloading chunks from other peers, but it does not have the complete content. And of course, it is uploading while downloading. 
A seeder has complete copies of the content. So it is only uploading.
A leecher can become a seeder once it finishes downloading. But a peer can't be both a leecher and seeder at the same time.

BR,
Rachel
