Concept Of Torrent - A Must Read

Torrents, typically ending in ".torrent", are control files for the peer-to-peer file sharing technology called BitTorrent.

It's actually pretty cool technology that really just boils down to another way to download files. So really, you just use .torrent files to download other files.


BitTorrent is a distributed file distribution technology. Yes, "distributed distribution". When you download a file using BitTorrent, the file is actually broken up into chunk that your BitTorrent client program then downloads and reassembles into the final file as the pieces arrive. To over-simplify, what makes it interesting are two things:

• The different chunks you download can all be coming from different machines. A BitTorrent client will connect to many other BitTorrent clients and download several chunks at once, in random order. In the long run this makes the protocol fairly efficient, and very nicely scalable - the more BitTorrent clients that are serving up a given file, the faster other clients can download it.

• As you start collecting chunks of the file, your BitTorrent client will start making those chunks available for downloading to other BitTorrent clients, and will become a part of the peer-to-peer file distribution network.

Torrent principle

The BitTorrent protocol was made mainly for temporarily very popular files - for example when a new movie or music album comes up. The download speed increases proportionately to the number of users downloading the same file and that is the biggest advantage of torrents.



When you are downloading something through torrent, you share your already downloaded part at the same time. When you start downloading, your application contacts a "tracker" server, which co-ordinates all clients (other users' applications). From the tracker the application finds out where to download from, which parts have the other users already downloaded and so on. Also your application informs the tracker about what part you were able to download until now - and by that it gives it at other users' disposal.


Seeder

A seed(er) is a client on the BT that has a complete copy of a particular archive. For any archive to work, there must be at least one seed to download from originally. Sometimes under certain circumstances, there may be no one seeder but enough people with all the parts to make up the whole archive, this is called a distributed copy.

Once your client finishes downloading, it will remain open until you click the Finish button. This is known as seeding. You can also start bit torrent client with a complete file, and once the bittorrent has checked the file it will connect and seed the file to others. It is good to continue seeding a file after you have finished downloading, to help others finish. Also, when a new torrent is posted to a tracker, someone must seed it in order for it to be available to others. The tracker doesn't know anything of the actual contents of a file, so it's important to follow through and seed a file if you upload the torrent to a tracker.

It is HIGHLY recommended that once you have gotten an archive you leave the BT client running for at least the amount of time that it took you to download the archive to help ensure that others will also be able to get it.
Share and Share alike!

Leecher

A leech(er) is a client on the BT network that does not have a complete copy of a particular archive yet. When any new client begins downloading an archive, they are a leecher until they have finished downloading the entire archive and then become a seeder. The name 'leecher' here is an unfortunate use that has become too commonly used even though it is really not applicable to what the meaning is. A leecher normally means someone who downloads without uploading (takes but does not give.) But here, a leecher is part of the network and is uploading as well, many times more KB than they download. But hey, it's worth the new meaning once you appreciate the vast resources that BT brings to you.

Reseed

When there are zero seeds for a given torrent (and not enough peers to have a distributed copy), all the peers will get stuck with an incomplete file, since no one in the swarm has the missing pieces. When this happens, someone with a complete file (a seed) must connect to the swarm so that those missing pieces can be transferred. This is called reseeding. Usually a request for a reseed comes with an implicit promise that the requester will leave his or her client open for some time period after finishing (to add longevity to the torrent).


What does it mean to "seed" a file after downloading ?

It is seeders who sent you the file, once you have finished downloading it is then your turn to pass the file on to someone else or provide the "SEED". Usually the ratio is 150% of the total file size. So in essense you are passing on a whole copy to one person and half of a copy to another.

so my TT FRIENDS ,please SEED after downloading ,so one of your other TT FRIEND can download and enjoy wat u hav downloaded.the main principle of the community is SEEDING and that concept dies rite there at your system when at once you STOPPED SEEDING.

SO PLEASE DONT HIT AND RUN
PLZ SEED AFTER DOWNLOAD BCOZ ITS EASY AND NOT GOING TO COST U ANYTHNG OR NOT GOING TO REDUCE YOUR DOWNLOAD SPEED.

SEEDING ALSO LESSEN THE WORK OF RELEASERS ,IF MORE THE PEOPLE SEED,THE RELEASER CAN MOVE AND HE CAN GIVE U MORE RELEASES.
