Bit. Torrent - Wikipedia. Bit. Torrent is a communications protocol of peer- to- peer file sharing (. Bit. Torrent is one of the most common protocols for transferring large files, such as digital video files containing TV shows or video clips or digital audio files containing songs.

Peer- to- peer networks have been estimated to collectively account for approximately 4. Internet traffic (depending on location) as of February 2. A Bit. Torrent client is a computer program that implements the Bit. Torrent protocol. Popular clients include . Bit. Torrent trackers provide a list of files available for transfer, and allow the client to find peer users known as seeds who may transfer the files. Programmer Bram Cohen, a former University at Buffalo student. Based on this figure, the total number of monthly Bit. Torrent users may be estimated to more than a quarter of a billion. By the time a copy to a destination computer of each of those parts completes, a copy to another destination computer of that part (or other parts) is already taking place between users. The tracker (server) provides only a single copy of the file, and all the users clone its parts from one another. Description. Rather than downloading a file from a single source server, the Bit. Ganool.IS is the Official Ganool. Watch Full New Movies, TV Series Online, Stream or Download Anime Free. Compatible with iPhone and latest Android mobile devices. The top 8 torrent sites 2016-17 are rounded up here to help you find torrent files of hot/new movies, music, games and software easily, and download them to your PC. Torrent protocol allows users to join a . The protocol is an alternative to the older single source, multiple mirror sources technique for distributing data, and can work effectively over networks with lower bandwidth. Using the Bit. Torrent protocol, several basic computers, such as home computers, can replace large servers while efficiently distributing files to many recipients. This lower bandwidth usage also helps prevent large spikes in internet traffic in a given area, keeping internet speeds higher for all users in general, regardless of whether or not they use the Bit. Torrent protocol. A user who wants to upload a file first creates a small torrent descriptor file that they distribute by conventional means (web, email, etc.). They then make the file itself available through a Bit. Torrent node acting as a seed. Those with the torrent descriptor file can give it to their own Bit. Torrent nodes, which. As each peer receives a new piece of the file it becomes a source (of that piece) for other peers, relieving the original seed from having to send that piece to every computer or user wishing a copy. With Bit. Torrent, the task of distributing the file is shared by those who want it; it is entirely possible for the seed to send only a single copy of the file itself and eventually distribute to an unlimited number of peers. Each piece is protected by a cryptographic hash contained in the torrent descriptor. If a node starts with an authentic copy of the torrent descriptor, it can verify the authenticity of the entire file it receives. Pieces are typically downloaded non- sequentially and are rearranged into the correct order by the Bit. Torrent Client, which monitors which pieces it needs, and which pieces it has and can upload to other peers. Pieces are of the same size throughout a single download (for example a 1. MB file may be transmitted as ten 1 MB pieces or as forty 2. KB pieces). Due to the nature of this approach, the download of any file can be halted at any time and be resumed at a later date, without the loss of previously downloaded information, which in turn makes Bit. Torrent particularly useful in the transfer of larger files. This also enables the client to seek out readily available pieces and download them immediately, rather than halting the download and waiting for the next (and possibly unavailable) piece in line, which typically reduces the overall time of the download. Once a peer has downloaded a file completely, it becomes an additional seed. This eventual transition from peers to seeders determines the overall . As more peers join the swarm, the likelihood of a completely successful download by any particular node increases. Relative to traditional Internet distribution schemes, this permits a significant reduction in the original distributor's hardware and bandwidth resource costs. Distributed downloading protocols in general provide redundancy against system problems, reduce dependence on the original distributor. If a BOINC distributed computing application needs to be updated (or merely sent to a user) it can do so with little impact on the BOINC Server. Each client is capable of preparing, requesting, and transmitting any type of computer file over a network, using the protocol. A peer is any computer running an instance of a client. To share a file or group of files, a peer first creates a small file called a . This file contains metadata about the files to be shared and about the tracker, the computer that coordinates the file distribution. Peers that want to download the file must first obtain a torrent file for it and connect to the specified tracker, which tells them from which other peers to download the pieces of the file. Though both ultimately transfer files over a network, a Bit. Torrent download differs from a classic download (as is typical with an HTTP or FTP request, for example) in several fundamental ways: Bit. Torrent makes many small data requests over different IP connections to different machines, while classic downloading is typically made via a single TCP connection to a single machine. Bit. Torrent downloads in a random or in a . However, this protection, theoretically, comes at a cost: downloads can take time to rise to full speed because it may take time for enough peer connections to be established, and it may take time for a node to receive sufficient data to become an effective uploader. This contrasts with regular downloads (such as from an HTTP server, for example) that, while more vulnerable to overload and abuse, rise to full speed very quickly and maintain this speed throughout. In general, Bit. Torrent's non- contiguous download methods have prevented it from supporting progressive download or . However, comments made by Bram Cohen in January 2. In January 2. 01. Cohen demonstrated an early version of Bit. Torrent streaming, saying the feature was projected to be available by summer 2. The peer creates a hash for each piece, using the SHA- 1 hash function, and records it in the torrent file. Pieces with sizes greater than 5. B will reduce the size of a torrent file for a very large payload, but is claimed to reduce the efficiency of the protocol. The exact information contained in the torrent file depends on the version of the Bit. Torrent protocol. By convention, the name of a torrent file has the suffix . Torrent files have an . Though SHA- 1 has shown signs of cryptographic weakness, Bram Cohen does not consider the risk big enough for a backward incompatible change to for example SHA- 3. The tracker maintains lists of the clients currently participating in the torrent. Azureus was the first. An alternative and incompatible DHT system, known as Mainline DHT, was released in the Mainline Bit. Torrent client three weeks later (though it had been in development since 2. The purpose of the flag is to prevent torrents from being shared with clients that do not have access to the tracker. The flag was requested for inclusion in the official specification in August 2. The client connects to the tracker(s) specified in the torrent file, from which it receives a list of peers currently transferring pieces of the file(s) specified in the torrent. The client connects to those peers to obtain the various pieces. If the swarm contains only the initial seeder, the client connects directly to it and begins to request pieces. Clients incorporate mechanisms to optimize their download and upload rates; for example they download pieces in a random order to increase the opportunity to exchange data, which is only possible if two peers have different pieces of the file. The effectiveness of this data exchange depends largely on the policies that clients use to determine to whom to send data. Clients may prefer to send data to peers that send data back to them (a . But strict policies often result in suboptimal situations, such as when newly joined peers are unable to receive any data because they don't have any pieces yet to trade themselves or when two peers with a good connection between them do not exchange data simply because neither of them takes the initiative. To counter these effects, the official Bit. Torrent client program uses a mechanism called . Peers arriving after the initial rush might find the content unavailable and need to wait for the arrival of a . The seed arrival, in turn, may take long to happen (this is termed the . Since maintaining seeds for unpopular content entails high bandwidth and administrative costs, this runs counter to the goals of publishers that value Bit. Torrent as a cheap alternative to a client- server approach. This occurs on a huge scale; measurements have shown that 3. It is possible to obtain the IP addresses of all current and possibly previous participants in a swarm from the tracker. This may expose users with insecure systems to attacks. However, there are ways to promote anonymity; for example, the One. Swarm project layers privacy- preserving sharing mechanisms on top of the original Bit. Torrent protocol. A moderate degree of anonymity, enough to keep ISPs from giving the user trouble at least, can be achieved with seedboxes such as Bitport. Tor does not provide anonymity on Bit. Torrent. This can be useful for users trying to avoid copyright complaints from their ISPs, maintaining privacy, or avoiding censorship. Bridging between i. It has a plugin that connects to the i. If the user adds a torrent from i. For this reason, torrents previously published only on i. Internet, and users of i. Internet while maintaining the anonymity of i. Independent adopters report that without using Bit. Torrent technology, and its dramatically reduced demands on their private networking hardware and bandwidth, they could not afford to distribute their files.
