How does BitTorrent work?

The bitTorrent protocol divides the file into tiny fragments, usually of the order of a quarter of a megabyte (256 KB), but as the original file is larger, with as much the fragments size increases. Usually a 4.37 GB file will be divided into fragments of 4 MB each (4096 KB). Users download missing fragments they need from those who have already downloaded them, providing the others with the fragments already taken. The protocol is pretty smart to choose the more efficient network connection linked to the fragments. A group of users simultaneously delivering a generic name of "swarm". For increase overall efficiency, BitTorrent clients require from other users the most rare fragments, in other words, fragments which are available at a few users in an attempt to ensure homogeneity of the fragments in terms of availability and to avoid "congestion."

Snippets are not downloaded in sequential order and must file the original reconstituted by BitTorrent client. It is very important that a customer within a cluster will start to provide the other fragments of the file before it has the complete file. Thus, anyone can have at the end the compled file, as long as somewhere in the cluster there is at least one copy of each fragment, even if no user has the full file (a full copy of the file is named "seed").
