INTRODUCTION TO "PEER TO PEER FILE SHARING" (P2P file sharing)

Peer to Peer file sharing has become one of the most popular way of sharing different contents like movies, songs ,softwares etc. on Internet. Many people don't even realize they are using P2P file sharing while downloading files using limewire or torrent client.

When we download something from a file sharing website or any other website we actually download the file from the website's server using the FTP protocol (FTP protocol are set of standard rules for file transfer) , now the servers have a bandwidth limit means there is a limit to the downloading speed, due to this the download speed can't go beyond a specific limit. This is called client server sharing. Downloading from popular sites can be fast, but there is always a limit.

Now lets take a look at P2P file sharing.Unlike centralized client-server sharing model P2P uses P2P networking for sharing contents. In P2P networking the users are directly connected to each other without any interference from any servers. Means the traffic does not pass through any servers. The users are called pears. All these peers are mostly equally privileged and act both as a client and server (consumer and supplier).
