  2. 4. <ul><li>Bit Torrent is a peer-to-peer file sharing protocol used for distributing large amounts of data. </li></ul><ul><li>Bit Torrent is one of the most common protocols for transferring large files, and it has been estimated that it accounts for approximately 27-55% of all Internet traffic as of February 2009. </li></ul>
  3. 5. <ul><li>Bram Cohen is the creator of Bit Torrent, which is now one of the most successful peer-to-peer programs ever. </li></ul><ul><li>Cohen first showed his code for the program at a hacker conference in 2002, so that he use the program to swap Linux software online cheaply and quickly. </li></ul>
  4. 6. <ul><li>Bit Torrent DNA means “Delivery Network Accelerator “. </li></ul><ul><li>This program is designed to speed up the viewing of streaming video, downloading software. </li></ul><ul><li>Higher quality video, faster software downloads, all with the security and reliability of a managed service. </li></ul>
  5. 7. <ul><li>Bit Torrent is a protocol designed for transferring files. </li></ul><ul><li>It is peer-to-peer in nature, as users connect to each other directly to send and receive portions of the file. </li></ul><ul><li>The key philosophy of Bit Torrent is that users should upload (transmit outbound) at the same time they are downloading (receiving inbound.) In this manner, network bandwidth is utilized as efficiently as possible. </li></ul>
  6. 8. <ul><li>Peer-to-peer file sharing is different from traditional file downloading. </li></ul><ul><li>You run peer-to-peer file-sharing software on your computer and send out a request for the file you want to download. </li></ul><ul><li>To locate the file, the software queries other computers that are connected to the Internet and running the file-sharing software. </li></ul><ul><li>When the software finds a computer that has the file you want on its hard drive, the download begins. </li></ul>
