Torrent is a peer-to-peer file sharing protocol used for distributing large amounts of data. Torrent is the most common protocols for transferring large files.
The protocol works initially when a file provider makes his/her file (or group of files) available to the network. This is called a seed and allows others, named peers, to connect and download the file. Each peer that downloads a part of the data makes it available to other peers to download. After the file is successfully downloaded by a peer, many continue to make the data available, becoming additional seeds. This distributed nature of Torrent leads to a viral 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 and reduces dependence on the original distributor.
Programmer Bram Cohen designed the protocol in April 2001 and released a first implementation on July 2, 2001. It is now maintained by Cohen’s company BitTorrent, Inc. There are numerous BitTorrent clients available for a variety of computing platforms. According to isoHunt, the total amount of shared content is currently more than 1.7 petabytes.
Torrent principle
The Bit-Torrent protocol was made mainly for temporarily very popular file transfer – for eg: when a new music album movie or comes up. The download speed increases proportionately to the number of users downloading the same file & that is the biggest advantage of torrents.
Bit-Torrent-working
When you are downloading through torrent, you share your already downloaded part at the same time (for this reason you break the law in most countries when you are downloading illegal data). When you start download, first your application contacts a “tracking” server, which co-ordinates all clients (same time other users’ applications). From the tracker the application finds out where to download from, which parts have the other users already downloaded? & so on. Same time your application informs the tracker about what part you were able to download until now – and by that it gives it at other users’ disposal.
Some Problems also:
When the tracker server is not functional may turn up, you can’t begin downloading, but if you already are downloading data, it doesn’t have to be necessarily a problem to finish the download (your client already knows where to download from).
Then there may be no one downloading or sharing but you. Therefore you have nowhere to download from. This happens with old and unpopular torrents.
Theoretically a situation when there is nobody that has the file complete may come up (such user is called “seed” or “seeder”) and you simply can’t get the whole file together from the parts other users have.
Download Torrent
uTorrent
The most commonly used torrent client. It is very popular for its simplicity, reliability and also its size -its around 200KB. It has a very nice web site, including extensive forums – if you have any problems. The clear choice for newbies! The “u” at the beginning of the name means micro, they rather use “u” because it’s easier to write and there are no problems with encoding.
