In computing, and specifically peer-to-peer file sharing, seeding is the uploading of already downloaded content for others to download from. A peer, a computer that is connected to the network, becomes a seed when having acquired the entire set of data, it begins to offer its upload bandwidth to other peers attempting to download the file.
The hash is a digital fingerprint in the form of a string of alphanumeric characters (typically hexadecimal) in the .torrent file that the client uses to verify the data that is being transferred. "Hash" is the shorter form of the word "hashsum". Torrent files contain information like the file list, sizes, pieces, etc.
In the BitTorrent file distribution system, a torrent file or meta-info file is a computer file that contains metadata about files and folders to be distributed, and usually also a list of the network locations of trackers, which are computers that help participants in the system find each other and form efficient distribution groups called swarms.

In file sharing, super-seeding is an algorithm developed by John Hoffman for the BitTorrent communications protocol that helps downloaders become uploaders more quickly, but it introduces the danger of total seeding failure if there is only one downloader. [citation needed] The algorithm applies when there is only one seed in the swarm.
A BitTorrent tracker is a special type of server that assists in the communication between peers using the BitTorrent protocol.. In peer-to-peer file sharing, a software client on an end-user PC requests a file, and portions of the requested file residing on peer machines are sent to the client, and then reassembled into a full copy of the requested file.
Users wishing to obtain a copy of a file typically first download a torrent file that describes the file(s) to be shared, as well as the URLs of one or more central computers called trackers that maintain a list of peers currently sharing the file(s) described in the .torrent file. In the original BitTorrent design, peers then depended on this ...
BitTorrent files can be seen conceptually as a hyperlink. However, it can also be a very specific instruction for how to obtain content on the internet. BitTorrent may transmit or include illegal or copyrighted content. Court decisions in various jurisdictions have deemed some BitTorrent files illegal.
It supports saving of sessions and allows the user to add and remove torrents. It also supports partial downloading of multi-file torrents. In the release of rTorrent-0.7.0 support for BitTorrent protocol encryption was also implemented. [6] PEX, DHT and initial seeding were recently [when?] implemented in rTorrent.
