Peer-to-peer (P2P) file sharing is the practice of connecting with other computer users to trade files over the Internet. Large online media "shared folders" are common - for example, anyone can put a free copy of their mp3 music in one folder and allow others to download it. The most well known P2P networks are Napster, Gnutella, Kazaa, iMesh and LimeWire. This method allows people to get access to media files that they wouldn't be able to through direct connections between computers on an open network or via websites. Using peer-to-peer technology may also mean you don't have to wait until your download is finished to share with others.
