BitTorrent is a peer-to-peer file sharing protocol used to distribute large amounts of data. BitTorrent is one of the most common protocols for transferring large files. Its main usage is for the transfer of large sized files. It makes transfer of such files easier by implementing a different approach. A user can obtain multiple files simultaneously without any considerable loss of the transfer rate. It is said to be a lot better than the conventional file transfer methods because of a different principle that is followed by this protocol. It also evens out the way a file is shared by allowing a user not just to obtain it but also to share it with others. This is what has made a big difference between this and the conventional file transfer methods. It makes a user to share the file he is obtaining so that the other users who are trying to obtain the same file would find it easier and also in turn making these users to involve themselves in the file sharing process. Thus the larger the number of users the more is the demand and more easily a file can be transferred between them.
BitTorrent protocol has been built on a technology which makes it possible to distribute large amounts of data without the need of a high capacity server, and expensive bandwidth. This is the most striking feature of this file transfer protocol. The transferring of files will never depend on a single source which is supposed the original copy of the file but instead the load will be distributed across a number of such sources. Here not just the sources are responsible for file transfer but also the clients or users who want to obtain the file are involved in this process. This makes the load get distributed
