Detailed explanation-1: -Typically, BitTorrent uses TCP as its transport protocol for exchanging pieces, and it uses HTTP for tracker comms. The well known TCP port for BitTorrent traffic is 6881-6889 (and 6969 for the tracker port). The DHT extension (peer-to-peer tracker) uses various UDP ports negotiated by the peers.
Detailed explanation-2: -BitTorrent is a distributed peer-to-peer system which, it is stated, has the potential to change the landscape of broadcast media and file distribution. It uses a symmetric (tit-for-tat) transferring model in an attempt to reach Pareto efficiency.
Detailed explanation-3: -Peer-to-peer BitTorrent Each client uploads their part of the file to other clients while simultaneously downloading bits of the file they don’t have from other clients. All the clients work together as a swarm to share the file.
