Bittorent

What is Bittorent?? BitTorrent is the global standard for delivering high-quality files over the Internet. It is a method of distributing large amounts of data widely without the original distributor incurring the entire costs of hardware, hosting and bandwidth resources. Instead, when data is distributed using the BitTorrent protocol, each recipient supplies pieces of the data to newer recipients, reducing the cost and burden on any given individual source, providing redundancy against system problems, and reducing dependence on the original distributor.

You also can get bittorent clients at this site:-

1. The one that started it all, the original BitTorrent client by Bram Cohen. It runs on any platform Python runs on (practically everything) and features a text-only mode. Get this if you just want to get a file without much fuss.

2. BitTornado by TheShad0w; it´s the descendant of TheShad0w´s experimental client, which itself was based on an experimental build of the original BitTorrent. This client features an enhanced GUI, lots of new features under the hood, and is generally one of the most advanced clients out there. Get this if you need to limit your bandwidth or generally want more control. It runs on the same platforms the original BitTorrent runs on, and also features a console mode.

3. Azureus is a BitTorrent implementation in Java (and, as such, runs wherever Java runs). It easily supports multiple concurrent BitTorrent downloads, can be tweaked to your heart´s desire, and is constantly updated. Get this if you need a powerhorse, but make sure you have a reasonably recent Java Virtual Maschine installed.
