Answer

1. Break Down the Problem

   • Identify the protocols used in BitTorrent for two specific functions: exchanging pieces of data and communicating with the tracker.

2. Relevant Concepts

   • BitTorrent operates primarily over TCP for reliable data transmission. It also uses a variety of protocols for tracker communication.

3. Analysis and Detail

   • Exchanging Pieces: BitTorrent uses TCP for transferring data pieces between peers. TCP ensures that all packets are delivered accurately and in order, making it ideal for file transfers.
   • Tracker Communication: Trackers communicate using HTTP. This is because HTTP works well for client-server communication, allowing peers to get the list of other peers sharing the same file.

4. Verify and Summarize

   • For exchanging pieces, the protocol used is TCP.
   • For tracker communication, the protocol used is HTTP.

Final Answer

Torrent uses b. TCP for exchanging pieces, and it uses c. HTTP for tracker communications.
