A torrent file
is a
peer-to-peer
file sharing
protocol used for distributing large amounts of
data.
BitTorrent is one of the most common protocols for transferring
large files, and by some estimates it accounted for approximately
35% of all traffic on the entire
Internet in 2004.
The protocol works when a file provider initially makes his/her
file (or group of files) available to the network. This is
called a seed and allows others, named peers, to connect and
download the file. Each peer that downloads a part of the data makes
it available to other peers to download. After the file is successfully
downloaded by a peer, many continue to make the data available,
becoming additional seeds. This distributed nature of BitTorrent
leads to a viral spreading of a file throughout peers. Relative
to standard
Internet hosting, this provides a significant reduction in the
original distributor's
hardware and
bandwidth resource costs. There are numerous
BitTorrent clients available for a variety of
computing platforms. According to
isoHunt,
the total amount of shared content is currently more than 1.7
petabytes. Source: Wikipedia.
