Techopedia explains BitTorrent Client
BitTorrent Client is primarily designed to enable peer-to-peer communication services through the BitTorrent protocol for sharing, downloading and seeding data to a group of globally connected peers powered by the same protocol.
BitTorrent client tools work by enabling a local user to find desired torrents and downloading torrents that relate to a file or data. BitTorrent client connects with the central server through the underlying protocol, which in turn activates all the peers or trackers who have part of or the complete torrent file. Upon successful authorization and connection, BitTorrent client initiates the fetching of data from the remote peers to the local machine and reconstructs the file to its original state after downloading.
