Client A BitTorrent client is any program that implements the BitTorrent protocol. Each client is capable of preparing, requesting, and transmitting any type of computer file over a network, using the protocol.
PeerThese are the clients who are
responsible for the file transfer.Peers = leechers + seeds.Downloading speed of any file
using torrent depends on number of peers.
Seeder
Someone who has finished downloading and is only uploading
Leecher
Someone who is downloading
TrackerA BitTorrent tracker, for those of you that don't remember, is a server that regulates the communication between those downloading and uploading torrents.
General Idea of BitTorrent
File is broken in to many different pieces
Each piece is downloaded in a “rarest” first order
As peers get more pieces they seed those until 100% - then they become a seed
