Problem
Consider peer X that joins BitTorrent to download the pieces of a file F from a seeder as well as from its peers. However, peer X does not want to upload any of its own pieces (i.e., X is a free-rider!).
i. Explain why it is or it is not possible for peer X to download a complete set of pieces of file F.
ii. Explain why or why not peer X can download a complete set of pieces of file F faster if peer X uses multiple computers to download the pieces.
