Comparison of BitTorrent clients

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 146.64.81.8 (talk) at 09:40, 19 August 2010 (Operating system support: utorrent support for windows was listed as partial with wine and full linux. its the other way round). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

A BitTorrent client is a computer program that manages downloads and uploads using the BitTorrent protocol.

The first client, known as BitTorrent, was created by Bram Cohen, in October 2002.

Many subsequent clients have been at least partially based on it. Not all clients were originally built for BitTorrent, having added support for the protocol later on. There have been attempts to package malware as BitTorrent clients, probably due to the availability of many legitimate clients and users' willingness to try new ones.

The following tables compare general and technical information for a number of applications supporting the BitTorrent protocol. They are neither all-inclusive nor necessarily up to date.

However, some trackers that register their users for keeping tabs on fair usage (such as a ratio of bytes downloaded to uploaded) may not reliably measure and update usage for users employing DHT.

Each peer has an index of directories and files that it shares with peers that it is connected to. No one peer is responsible for storing the entire directory structure, it is distributed among everyone. It is collaboratively maintained, edited and built upon by all users in a popularity based system.
