If you continue to run the BitTorrent client software after the download is complete, others may receive.Your computer receives multiple parts of the file simultaneously. The tracker helps the client software exchange parts of the desired file with other computers in the swarm.The tracker identifies connected computers that have all or part of the file and are in the process of sending or receiving it.The BitTorrent client software communicates with a tracker to find other computers running BitTorrent that have the full file (seed computers) and those with a portion of the file (peers). You open a web page and click on a link for the file you want to download.In order for a torrent to be downloaded, a seeder, which has a complete copy of all the files in the torrent, must initially join the swarm so that other users can download the data. Users who remain connected to a BitTorrent swarm even after downloading the entire file are called “ seeders” as they contribute more upload bandwidth so that others can continue downloading files. Users who download from a BitTorrent swarm are known as “leechers” or “ peers“. In this way the user receives multiple parts of the file to be downloaded simultaneously.Īnd, of course, the greater the number of computers involved in the swarm, the faster the file transfer. One of its most outstanding features is that it uses a principle called “tit-for-tat” since, in order to receive files, you must also provide them and the more files you share with others, the faster your downloads will be.įinally, as we have already mentioned, to ensure fast download times, BitTorrent downloads different parts of a file simultaneously from multiple computers.īehind this system there is a tracker that identifies the connected computers that have all or part of the file and that participate in the sending and receiving process. BitTorrent is a peer to peer protocol that offloads part of the file tracking work to a central server (called a tracker).
