-BitTorrent is a protocol for downloading and distributing files across the Internet. In contrast with the traditional client/server relationship, in which downloaders connect to a central server (for example: watching a movie on Netflix, or loading the web page you're reading now), participants in the BitTorrent network, called **peers**, download pieces of files from *each other*—this is what makes it a **peer-to-peer** protocol.
