P2P

File sharing refers to providing access to digitally stored information such as computer programs, audio, images, videos, documents, or electronic books.

Peer-to-peer, or P2P, refers to a computer network where each computer can act as a client or server for the other computers in that network, allowing shared access to files without the need for a central server.

The first peer-to-peer application was the file sharing system Napster. Others include Kazaa and WinMX. Just be careful how you use it, you don't want to end up like the Minnesota mom who was hit with a $1.5 million dollar fine for illegally downloading music through the peer-to-peer file-sharing network Kazaa in 2006!
