How to download files using Torrent?

FTP(File Transfer protocol)

over traditional FTP
What is BitTorrent?
P2P(Peer To Peer) file transfer protocol
Transfer of large files
Files are shared by many users
Active participation of all users
Huge success in file sharing domain since 2003
How it works?
To share the data using BitTorrent we must
Tracker server, a file with .'torrent' extension,
complete copy of the file being shared
.torrent file conatins data which is essential for
the protocol to function- file length, file name,
information about the tracker
When we open .'torrent' file in client, it will
connect to the client and start downloading
This refers to the small metadata file you
receive from the web server (the one that ends
in .torrent.) Metadata here means that the file
contains information about the data you want to
download, not the data itself.
A peer is another computer on the internet that
you connect to and transfer data. Generally a
peer does not have the complete file.
They are similar to peers in that they won’t
have the complete file. But the main difference
between the two is that a leech will not upload
once the file is downloaded.
A computer that has a complete copy of a
certain torrent. Once a client downloads a file
completely, he can continue to upload the file
which is called as seeding. This is a good
practice in the BitTorrent world since it allows
other users to have the file easily.
A server on the Internet that acts to coordinate
the action of BitTorrent clients. The clients are
in constant touch with this server to know about
the peers in the swarm.
The group of machines that are collectively
connected for a particular file.
