Peer to Peer (P2P) refers to a self organized network, in which each connected computer has equal rights and functions at the same time as a server and a client.
One thing that can be accomplished by such a network is file-sharing (another one is for example VoIP like Skype), where each downloader automatically turns into an uploader for other downloaders.
To access a P2P network one needs a dedicated application, based on different prior conditions, depending which P2P technology you decide to use.
Broadly known names are for example 'BitTorrent'‚ 'qBTorrent'‚ 'BitComet‘, uTorrent'‚ 'eMule‘ and Vuze.
Peer to Peer filesharing is most commonly known for its role in how Torrents work.
This type of file sharing can be is very effective, allowing for greater download speeds as opposed to downloading from a website (which usually stores files on an actual server).
Peer to Peer is not prone to being limited by any particular file hosting service and part of its efficiency has to do with the fact that each downloader can also be an uploader, even if they haven't finished downloading the entire file (they can instantly start uploading any parts of the download they already have).
However, Torrent Trackers can be blocked in certain countries and in some areas, even downloading Torrents (regardless of the nature of the file) is frowned upon.
