| Torrent is a P2P file sharing protocol used for distributing many files. It is one of the most widely used protocols for files distribution.A torrent means a torrent meta-data file or all files described by it and contains meta-data about all the downloadable files. Meta-data files aren't stored on the torrent host site, but are disseminated among many torrent file servers. Each torrent file guides to a trackers site, which centrally coordinates the PEER-TO-PEER transfer of data among Internet users and keeps record of all the downloaders and seeders of the certain file. One tracker server can monitor concurrent downloads of a few files. Following the link to the torrent meta-data file, a user gets from the tracker site a list of peers presently transferring bits of the files, with whom a direct connection to barter bits of the file can be established. A file ready for downloading via Torrent is known as a seed. A person who has the completed file and uploads or seeds it back to the web is called a Seeder. The more seeders, the better.A leecher is a person who downloads, or leeches, the file from the presently available seeds. As new leechers connect to the Internet and request the same file, their PC receives a different bit of the data from the seeder. Once several seeders have at their command several pieces of the seed, a source for that part of the file. So, the task spreads among the seeder and many peers, which easens the initial user. As soon as the file is downloaded by a given leecher, the peer is able to switch roles and become an extra seed, helping the remaining peers to get the entire file.Thanks to the nature of Torrent, files can be spread very quickly. For a secure and quick download, pick the torrents with more seeders than leechers, and read comments, if there are any. It will preclude you from downloading low quality or infected data. It should be mentioned, however, that torrent sites are less prone to viruses than PEER-TO-PEER programs. It is crucial to let your torrent-downloaded file seed so that you get a ratio of at least 1.0. This ratio means that you have seeded a file in exchange for the downloaded one. Some tracker sites count the quantity of data disseminated and downloaded by every user, and a insufficient ratio can be penalized with a bad download speed. Moreover, disconnecting as soon as the file is downloaded violates the idea of cooperation, which is the core principle of Torrent. |
