Types of file sharing

There are many options for sharing files on the Internet. One of the most popular is peer-to-peer networks, or P2P networks. Some of the most popular networks are FastTrack, Gnutella, Gnutella2 and eDonkey network. With these networks, the user downloads a program to their computer that allows them to connect to the network. Then with this program the user can search the shared media on other users’ computers and download this media from them across the Internet. These networks allow the sharing of any type of digital content, including songs, DVD-quality movies, computer programs and video games.
One of the most popular ways to get very large files like movies, computer applications, and video games is to use BitTorrent, another type of peer-to-peer network. With BitTorrent large media files are broken down into smaller chunks, which are then transferred to the user (or peer) depending on the fastest possible connection to the missing piece; all of this is done while the user is uploading the pieces it already has to other users. While this type of file sharing is most popular and useful for large movies and games, it can also be used for music, but usually users download music by the album or artist instead of a couple of songs.
File sharing can be done with no use of peer-to-peer technologies, for example by the use of a file hosting service. These sometimes also provide collaboration tools such as forums and groups, and allow links for direct downloads to be embedded in other communications such as emails and websites.
