Torrent - The Low Down...



I was first introduced to Torrents when a website called BtJunkie was the number one source for Torrents. Today I willl enlighten thee on the Torrents...



When BtJunkie was shut down, I then found the next best thing on a website called Demonoid. But this site was also shortlived....

Now if you need good Torrents, you go to ThePirateBay or KickAssTorrents, but in order to download you must have a Bitorrent client installed on your computer...

Some clients are BitThief developed by Distributed Computing Group, BitTorrent developed by Bram Cohen; BitTyrant developed by University of Washington, Free Download Manager developed by alervd, and ĀµTorrent developed by Ludvig Strigeus. My personal favourite client is uTorrent...


A Torrent file is a computer file that contains metadata about files and folders to be distributed, and usually also a list of the network locations of trackers, which are computers that help participants in the system find each other and form efficient distribution groups called swarms.

A torrent file does not contain the content to be distributed; it only contains information about those files, such as their names, sizes, folder structure, and cryptographic hash values for verifying file integrity.

Depending on context, a torrent may be the torrent file or the referenced content. Torrent files are normally named with the extension .torrent, as in MyFile.torrent.

Typically, Internet access is asymmetrical, supporting greater download speeds than upload speeds, limiting the bandwidth of each download, and sometimes enforcing bandwidth caps and periods where systems are not accessible. This creates inefficiency when many people want to obtain the same set of files from a single source; the source must always be online and must have massive outbound bandwidth. The BitTorrent protocol addresses this by decentralizing the distribution, leveraging the ability of people to network "peer-to-peer", among themselves.



Each file to be distributed is divided into very small information chunks called pieces. Downloading peers achieve rapid download speeds by requesting multiple pieces from different computers in the swarm. Once obtained, these pieces are usually immediately made available for download by others in the swarm. In this way, the burden on the network is spread among the downloaders, rather than concentrating at a central distribution hub or cluster. As long as all the pieces are available, peers (downloaders and uploaders) can come and go; no one peer needs to have all the chunks, or to even stay connected to the swarm in order for distribution to continue among the other peers.

A small torrent file is created to represent a file or folder to be shared. The torrent file acts as the key to initiating downloading of the actual content. Someone interested in receiving the shared file or folder first obtains the corresponding torrent file, either by directly downloading it, or by using a magnet link. The user then opens that file in a BitTorrent client, which automates the rest of the process. In order to learn the Internet locations of peers which may be sharing pieces, the client connects to the trackers named in the torrent file, and/or achieves a similar result through the use of distributed hash tables. Then the client connects directly to the peers in order to request pieces and otherwise participate in a swarm. The client may also report progress to trackers, to help the tracker with its peer recommendations.

When the client has all the pieces, it assembles them into a usable form. It may also continue sharing the pieces, elevating its status to that of seeder rather than ordinary peer.

In simpler terms, a torrent is a way of downloading and file sharing tjhat guarantees that your download will complete and you will have no missing files...
