BitTorrent is basically not a program instead it is a way or method for downloading large files like videos,albums etc using a distributed peer-to-peer sharing system. Some programs are written in the BitTorrent protocol to download files from the server called BitTorrent clients. BitTorrent is a little bit confusion to new users because it is slightly different from the older programs like Kazaa,Limewire etc. In this torrent the large file is divided intlo several small chunks of data with a lesser size.The main advantage here as soon as the small amount of data is downloaded,it can be shared with others that is there is no need of waiting foe the entire large file to be downloaded.The BitTorrent was written by Bram Cohen in Python.This is made available from the year 2001.It is a open source license available to anyone and can be downloaded from internet.This operates and works effectively over networks with lower bandwidths. The classic download in BitTorrent can be made with either HTTP or FTP request.
