May be that's the question some people may be asking. How does torrents work. How does people share files with each other. How does it all began. Its a short story and the beginning has to do with some hackers work. Some hackers, the official bittorrent creator were busy with their hacking work to send files bit by bit from a system to large numbers of computers so that they can't be tracked of being downloaded by a single machine but by a group of machine that's how it all happened. Now people ask how does it works. Let me explain you that it works in as a Peer to Peer file sharing manner. Like you have a file and you want to share with a group of friends may be a group of lots of friends. What you do is you use those file sharing application to create a .torrent file. This torrent file contains your file being shared hash code, file size, and others that are required to determine your system and your file being used. After creating these .torrent file you upload them in tracker sites like thePirateBay, bitjunkie, and others so that your friends could share. Ok so they download that file if they want to get that file from you and use the torrent application to get it from you. What is happening behind the scene is that tracker informs your system that this system wants to have your file and a handshake protocol (TCP)is done between You and your friend system (not with tracker) to have a lock between you and your friend system and you start sharing file with your friend using UDP protocol. That it you now have become the first seeder of your file and your friend system has became your new peer. As more friends join in more such handshake and sharing. Now this handshake is not just done with you but with other peers too. That's what file sharing is. Your lots of friends will share file like this using their own resources like their bandwidth, CPU speed and their disk space to share file in P2P system. When you first share your file you become seeder, when your friends first download them they become peers and when they completed their download they also become seeders. They also share file when they work as peers. And when someone stopped sharing they become lechers. So that's how it really works and it began to dominate the world internet since 2001.
