P2P

1) File sharing is when you transfer files from one person to another over the internet. 

2) P2P File sharing is the process of sharing and transferring digital files from computer to another. Each peer is an end-user's computer connected to the other peer through the internet. For this to work you need to download and install the P2P software programs and this is beneficially for people because it makes sharing large files easier. 

3) Some examples of P2P File sharing include napster, BitTorrent and even Skype. All of these different P2P File Sharing sites have various uses which all greatly benefit our society. 

It allows everyday people to download movies, albums of pictures, TV series, and of course the hottest songs for essentially no cost. The largest issue with P2P File Sharing is the legality of the various activities. A portion of the P2P File Sharing involve piracy and can lower the projects of many entertainment industries. An interesting point an article by Eric Pfanner from the NYT mentions the point of perspective in regards to piracy. Eric states "If you put 200 VCRs in your garage and start making and selling copies of films, you will get a visit from the police, If you do it from a Web site, everybody says, ‘Hey, freedom of information' ".
