This has been answered, but I'll do it again:
Demonoid is a website and BitTorrent tracker created by an anonymous Serbian known only by the pseudonym "Deimos" and "Zajson". The website indexes torrents uploaded by its members. It is the second largest,[3][4] and is the most popular, Public tracker,[5] and is ranked the 403rd most popular website overall in December 2008, according to Alexa.[6] Demonoid's torrent tracker had an estimated 3 million peers in September 2007.[5] The site had over 252,427 torrents indexed as of May 3, 2009 (torrents uploaded prior to August 4, 2005 were removed to free server resources).
A BitTorrent tracker is a server that assists in the communication between peers using the BitTorrent protocol. It is also, in the absence of extensions to the original protocol, the only major critical point, as clients are required to communicate with the tracker to initiate downloads. Clients that have already begun downloading also communicate with the tracker periodically to negotiate with newer peers and provide statistics; however, after the initial reception of peer data, peer communication can continue without a tracker.
BitTorrent protocol allows users to distribute large amounts of data without the heavy demands on their computers that would be needed for standard Internet hosting. A standard host's servers can easily be brought to a halt if high levels of simultaneous data flow are reached. The protocol works as an alternative data distribution method that makes even small computers (e.g. mobile phones) with low bandwidth capable of participating in large data transfers.
First, a user playing the role of file-provider makes a file available to the network. This first user's file is called a seed and its availability on the network allows other users, called peers, to connect and begin to download the seed file. As new peers connect to the network and request the same file, their computer receives a different piece of the data from the seed. Once multiple peers have multiple pieces of the seed, BitTorrent allows each to become a source for that portion of the file. The effect of this is to take on a small part of the task and relieve the initial user, distributing the file download task among the seed and many peers. With BitTorrent, no one computer needs to supply data in quantities which could jeopardize the task by overwhelming all resources, yet the same final result—each peer eventually receiving the entire file—is still reached.
After the file is successfully and completely downloaded by a given peer, the peer is able to shift roles and become an additional seed, helping the remaining peers to receive the entire file. This eventual shift from peers to seeders determines the overall 'health' of the file (as determined by the number of times a file is available in its complete form).
This distributed nature of BitTorrent leads to a flood like spreading of a file throughout peers. As more peers join the swarm, the likelihood of a successful download increases. Relative to standard Internet hosting, this provides a significant reduction in the original distributor's hardware and bandwidth resource costs. It also provides redundancy against system problems, reduces dependence on the original distributor and provides a source for the file which is generally temporary and therefore harder to trace than when provided by the enduring availability of a host in standard file distribution techniques.
