Explanation:
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.
