The document explains the foundational concepts of the BitTorrent protocol, including the terms 'seeds,' 'peers,' and 'leeches.' Seeds represent users uploading a fully downloaded file to the network, promoting availability. Peers are individuals actively sharing portions of the file, whether uploading or downloading. Leeches are users primarily downloading while contributing minimal upload. BitTorrent operates as a decentralized peer-to-peer solution to efficiently distribute large files, reducing bandwidth pressures on central servers while remaining resilient to censorship.
