Bit torrent
- 2. • A bit torrent is a file that links you to a torrent tracker. You can think of it like a signpost that shows you where your file will be. Many other people can all also download the same file as you at the same time. Each one of them is given different pieces of the file at different times, which they in turn pass onto you. And as part of the torrent, you also pass pieces of this file to other people. So by making everyone in the swarm help with the file, your download rate can be greatly increased.
- 3. • Services on the internet operate in a peer to peer mode. • Bittorent is a file sharing service through which the internet users can exchange files. • The great thing with bit torrent is that as the number of people downloading something increases, the faster the download speed becomes for all those involved. • Bittorent requires the users computer to act as both a client and a server because when requesting files from another user, the computer behaves like a client • Switches to server mode when it provides a file stored on its hard drive to another computer

- Slide 1Bit torrent by definition is just a file transfer protocol. A Bit Torrent client is the application which uses that protocol. You can use BitTorrent to share and download any type of file you want.is the global standard for delivering high-quality files over the Internet.The more popular a large video, audio or software file, the faster and cheaper it can be transferred with BitTorrent. is a protocol (a set of rules and description of how to do things) allowing you to download files quickly by allowing people downloading the file to upload (distribute) parts of it at the same time.BitTorrent is often used for distribution of very large files, very popular files and files available for free, as it is a lot cheaper, faster and more efficient to distribute files using BitTorrent than a regular download.
- Slide 2BitTorrent is a protocol that enables fast downloading of large files using minimum Internet bandwidth. Unlike other download methods, BitTorrent maximizes transfer speed by gathering pieces of the file you want and downloading these pieces simultaneously from people who already have them. This process makes popular and very large files, such as videos and television programs, download much faster than is possible with other protocols.
- Slide 3Traditional Client-Server DownloadingYou open a web page and click a link to a download a file to your computerThe web browser software on your computer (which is called the client) tells the server(a central computer that holds the web page and the file you want to download) to transfer a copy of the file to your computerThe transfer speed is affected by a number of variables, including the type of protocol, the amount of traffic on the server, and the number of other computers that are downloading the file.The transfer is handled by a protocol ( set of rules) such as FTP (file transfer protocol) or HTTP (Hyper text Transfer ProtocolIf the file is both large and popular the demands on the server are great and the download will be slow.
- Slide 4How Does It Work?The peer would be a user who would like to download one of our videos. They don’t have the video yet, all they have is a small .torrent file that they got from a friend, off of a web site, or in an RSS feed. The seeder is someone who has already downloaded the entire video and is sharing the bandwidth to all of the peers. And the tracker is what manages all of these connections in the background, telling all of the software how to connect with one another…You have a file and I want it. I get in the queue and wait for the others in front of me to download it, then I get a turn. Now lets look at how Bit Torrent works. First of all, imagine I have a book, with 100 pages, and 10 people want it. I give 10 pages to each person, and between them they have the whole book. I can then drop out of the file exchange and leave them to copy bits between themselves until they all have the full book. It works the same with files. The file being shared is broken up into smaller pieces. The tracker keeps track of who has what pieces and helps those looking for pieces to get them, while helping those with the pieces share them out to those looking.

- Slide 6peer-to-peer communications is implemented by giving each communication node both server and client capabilities. In recent usage, peer-to-peer has come to describe applications in which users can use the Internet to exchange files with each other directly or through a mediating server.Peer-To-Peer (PTP) is the process of sharing point statuses directly to other controllers on a network without having to pass data through the head end PCallows us to share files with other people, like our friends or even complete strangers.However, you have to be careful because file sharing, as well as file downloading, often breaks copyright lawsHow does P2P work?Is a communication model based in nodes for sharing filesFor traditional based networks, there is a centralized server that everyone needs to connect to in order to be in the network. The disadvantage of this system is that when the server fails, the network stops working. In the peer-to-peer network, each network user becomes a “server.” This means each user of the network is connected to all of the other users, and vice-versa. The advantage of this system is that when one user (“server”) stops working, the network is still functioning because other users are also acting as “servers.”
