What is BitTorrent?
BitTorrent is a peer-to-peer protocol which allows users to connect directly to each other to send and receive parts of a file through a central server called a “tracker”. The tracker itself does not contain or transmit any information pertaining to the actual content. It only coordinates and manages connections between peers.
BitTorrent is a protocol designed for transferring files. It is peer-to-peer in nature, as users connect to each other directly to send and receive portions of the file. However, there is a central server (called a tracker) which coordinates the action of all such peers. The tracker only manages connections, it does not have any knowledge of the contents of the files being distributed, and therefore a large number of users can be supported with relatively limited tracker bandwidth. The key philosophy of BitTorrent is that users should upload (transmit outbound) at the same time they are downloading (receiving inbound.) In this manner, network bandwidth is utilized as efficiently as possible. BitTorrent is designed to work better as the number of people interested in a certain file increases, in contrast to other file transfer protocols. One analogy to describe this process might be to visualize a group of people sitting at a table. Each person at the table can both talk and listen to a
BitTorrent is an open source peer-to-peer protocol for downloading files on the internet. Open source means the code is available for anyone to modify and redistribute at will. Consequently there are several free BitTorrent programs available to the public, each with differing features. The original source code was written by Bram Cohen. The idea behind BitTorrent is to allow massive distribution of popular files without penalizing the source by soaring bandwidth costs and possible crashes due to demand that exceeds the capability of the server. In this way, anyone who creates a popular program, music file or other product can make it available to the public regardless of assets, even if the file becomes highly popular. To understand how BitTorrent functions, first consider how normal downloading works. Personal computers connected to the Internet are known as clients while the websites visited reside on Internet servers. Servers “serve up information” to clients. If you surf to a site
