BitTorrent is a collaborative file-sharing protocol that is ideal for quickly distributing large amounts of data. Unlike other file-sharing techniques, BitTorrent does not rely on a cross-file sharing network, but builds a separate distribution network for each file.
To participate in the distribution of the data of a torrent, the client usually uses a torrent file (filename extension .torrent or .tor). This contains the IP address (or host name) of the tracker as well as the file name, size and a list of checksums of segments of the data to be downloaded (one or more files). Torrent files can be created with many available bittorrent clients. In this case, the initial Seeder Peer (seeder) must establish the link to the file to be offered as a torrent and keep it available.
