P2P Networks and Piracy
P2P = Peer to Peer(“Peer” – Rhymes with “beer”)Peers = Equals/People belonging to the same
category
A peer-to-peer computer network is a network that relies on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers.
- Wikipedia
P2P is all about sharing resources like• Your CPU Processing Time• Your bandwidth• Your disk space
Grid computing […] performs higher throughput computing by taking advantage of many networked computers to model a virtual computer architecture.
- Wikipedia
Grid computing is just sharing processing power across a network.
P2P evolved from the concept of grid computing as a means to share files between friends.
Client – Server Model Grid Computing P2P: Client =

P2P
Peers:A peer is another computer on the internet that you connect to and transfer data.
Torrent:Usually this refers to the small metadata file you receive from the web server or tracker you are downloading files from.
Seeders/seeds:A computer that has a complete copy of a certain torrent. Once your
client finishes downloading, it will remain open until you click the Finish/Stop button (or otherwise close it.) This is known as being a seed or seeding.
Swarm:The group of machines that are collectively connected for a particular file. For example, if you start a BitTorrent client and it tells you that you're connected to 10 peers and 3 seeds, then the swarm consists of you and those 13 other people.
Tracker:A server on the Internet that acts to coordinate the action of BitTorrent clients.
Ratio:In some torrent sites, you are expected to maintain a download to upload ratio.
Client:The program that enables p2p file sharing via the BitTorrent protocol. Examples of clients include µTorrent and Vuze.
Hash:The hash is a string of alphanumeric characters in the .torrent file that the client uses to verify the data that is being transferred.
Scrape:This is when a client sends a request to the tracking server for information about the statistics of the torrent.
Announce:A client announces that it wants to join the swarm and that server
should add it to the peers in that swarmPiece:This refers to the torrented files being divided up into equal specific
sized pieces
