Well, this question has to different answers depending on the timing. If you are referring to the "original Napster" then you are talking about the first "peer-to-peer" Internet based protocol, also known as P2P. This protocol revolutionized the Internet because it allows people to connect among themselves directly, sharing files on their particular hard-drives. Before that you could only download, whatever was already uploaded on an Internet Server. With P2P Napster technology, people can access your hard drive, as you can access others hard drives. A nice feature, is that if you started a download on "Pete's PC" and Pete went offline, your PC thru P2P will look for any other user owning the same file, and continue downloading from the point the connection was severed. Needless to say, this technology generated a very strong debate about copyrights and several lawsuits were extended to Napster and other sites who adopted P2P technology. In practical terms, if Pete have a song by U2 in his hard drive, anyone connected to the same P2P engine can download the song, and then being the song in two hard drives makes it easier for others to find, and so on and on. But that was the old P2P, in the glory days of Napster, Kazaa and E-mule. Now, Napster is basically a Media Vendor. If you want to download something is not free anymore, you have to pay rates that usually average in $1 per song. You can still find some pure P2P sites, but if you download a song without paying you can be charged for copyright infringement and be prosecuted by the proper authorities, having to pay lots of money in fines and depending on the magnitude of your transgression even go to jail. Is not a dream world anymore :(
