A BitTorrent client is an app used for peer-to-peer file sharing using the BitTorrent protocol. Such a program can prepare, request, and transmit any type of computer files over a network with the help of BitTorrent protocol. Computer with a running instance of a client app is considered a peer, hence peer-to-peer connection. To share an initial file, a small file with a 'torrent' extension is created on a peer machine. The torrent file contains metadata about the shared files and about the tracker, the computer coordinating distribution. In order to download shared files, peers need to obtain a torrent file first and then connect to a tracker, which coordinates them with other peers they can download pieces of file from.
