Bit Torrent- The new buzword for sharing


I know I might be getting some comments (or none) for explaining bit torrent now. It's been around for some time now and gaining in popularity.

Bit torrent is wonderful if you believe in fast downloads of files from the net through the simple way of sharing. Well, not very simple really. Well, for those of the very few bit torrent illeterates, here is a quick wrap up of the technology.

In normal P2P(peer to peer) downloads, a user tries to download a file from a single server. It's fine as long as a single user is downloading the file and the filesize is very small. But, when multiple users try to download the same file, then there will be issues like slow download speeds, breakage in downloads due to excessive load on the server.

Now, as I said before bit torrent works on the principle of sharing. Well, when a user starts to download from a server he has to keep uploading the part of the file he has downloaded as well. For eg; If you were downloading a movie, when you have downloaded about a part of the file you start uploading the file as well. All the other users downloading this file will also be doing the same. So, in affect you are downloading a file from multiple servers simultaneously thus, solving the bandwidth problem to a large extent and thus accounting for higher download speeds. Infact, I could download a hindi mp3 album of 80MB file size, on a 100KBPS system in about half an hour or a little more. This shows the efficiency of the system.

Right now, none of the browsers out there has bit torrent built into it. But, you can download a free tool from it's official website. Also, you can get all the documentation and help needed, on this site.
