Torrents

Bit-Torrents are computer programs that allow users to search and exchange computer files through a network. These files include anything from music to movies, games, and other computer software. These torrents are so successful because the torrents are gathering the information for these files from several other users on the network at once. There are many different bit-torrent programs available.
