Torrent :


A popular file sharing service developed by Bram Cohen that prevents
people from downloading constantly unless they are willing to share
in the overall transmission load on the network. Released in the
summer of 2001, BitTorrent is similar to KaZaA and other distributed
swapping services where users download from other users and do not
use a centralized directory as in the original Napster service.
However, BitTorrent is also different than all of them because it
makes every downloading user an uploading user.


Large Files Become Torrents

Instead of downloading an entire file, BitTorrent breaks a file into
chunks and distributes them among several participating users.
When you download a "torrent," you are also uploading it to another
user. BitTorrent balances the load because broadband download and
upload speeds are not the same. Users download files faster than
they can upload them, which makes them less interested in sharing
bandwidth to upload to someone else. BitTorrent ensures every user
participates in uploading.

BitTorrent has become widely used for transferring huge program files
as well as pirated movies. In 2004, one estimate placed BitTorrent
files as a third of all Internet traffic. Although the specific
amount for BitTorrent may vary, the combination of all file sharing
applications in use account for a huge chunk of traffic.
