Seeding (computing)
In computing, and specifically peer-to-peer file sharing, seeding is the uploading of already downloaded content for others to download from. A peer, a computer that is connected to the network, becomes a seed when having acquired the entire set of data, it begins to offer its upload bandwidth to other peers attempting to download the file. This data consists of small parts so that seeds can effectively share their content with other peers, handing out the missing pieces. A peer deliberately chooses to become a seed by leaving the upload task active once the content has downloaded. The motivation to seed is mainly to keep the file being shared in circulation (as there is no central hub to continue uploading in the absence of peer seeders) and a desire to not act as a parasite. The opposite of a seed is a leech, a peer that downloads more than they upload. Background Seeding is a practice within peer-to-peer file sharing, a content distribution model that connects computers with ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tit For Tat
Tit for tat is an English saying meaning "equivalent retaliation". It developed from "tip for tap", first recorded in 1558. It is also a highly effective strategy in game theory. An agent using this strategy will first cooperate, then subsequently replicate an opponent's previous action. If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not. Game theory Tit-for-tat has been very successfully used as a strategy for the iterated prisoner's dilemma. The strategy was first introduced by Anatol Rapoport in Robert Axelrod's two tournaments, held around 1980. Notably, it was (on both occasions) both the simplest strategy and the most successful in direct competition. An agent using this strategy will first cooperate, then subsequently replicate an opponent's previous action. If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not. This is similar to reciprocal altruism in biology. History The term develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decentralized Computing
Decentralized computing is the allocation of resources, both hardware and software, to each individual workstation, or office location. In contrast, centralized computing exists when the majority of functions are carried out, or obtained from a remote centralized location. Decentralized computing is a trend in modern-day business environments. This is the opposite of centralized computing, which was prevalent during the early days of computers. A decentralized computer system has many benefits over a conventional centralized network. Desktop computers have advanced so rapidly, that their potential performance far exceeds the requirements of most business applications. This results in most desktop computers remaining idle (in relation to their full potential). A decentralized system can use the potential of these systems to maximize efficiency. However, it is debatable whether these networks increase overall effectiveness. All computers have to be updated individually with new s ...

BitTorrent Tracker
A BitTorrent tracker is a special type of server that assists in the communication between peers using the BitTorrent protocol. In peer-to-peer file sharing, a software client on an end-user PC requests a file, and portions of the requested file residing on peer machines are sent to the client, and then reassembled into a full copy of the requested file. The "tracker" server keeps track of where file copies reside on peer machines, which ones are available at time of the client request, and helps coordinate efficient transmission and reassembly of the copied file. Clients that have already begun downloading a file communicate with the tracker periodically to negotiate faster file transfer with new peers, and provide network performance statistics; however, after the initial peer-to-peer file download is started, peer-to-peer communication can continue without the connection to a tracker. Modern BitTorrent clients may implement a distributed hash table and the peer exchange proto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Pirate Bay Raid
The Pirate Bay raid took place on 31 May 2006 in Stockholm, when The Pirate Bay, a Swedish website that indexes torrent files, was raided by Swedish police, causing it to go offline for three days. Upon reopening, the site's number of visitors more than doubled, the increased popularity attributed to greater exposure through the media coverage, which is an example of the Streisand effect. The raid, alleged by Pirate Bay to be politically motivated and under pressure from the Motion Picture Association of America (MPAA), was reported as a success by the MPAA in the immediate aftermath, but with the website being restored within days and the raising of the debate in Sweden, commentators such as ''TorrentFreak'' called the raid "highly unsuccessful". On 31 January 2008, Swedish prosecutors filed charges against four of the individuals behind The Pirate Bay for "promoting other people's infringements of copyright laws". Execution At roughly 11:00 UTC on 31 May 2006, a major raid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Pirate Bay Trial
The Pirate Bay trial was a joint criminal and civil prosecution in Sweden of four individuals charged for promoting the copyright infringement of others with the torrent tracking website The Pirate Bay. The criminal charges were supported by a consortium of intellectual rights holders led by the International Federation of the Phonographic Industry (IFPI), who filed individual civil compensation claims against the owners of The Pirate Bay. Swedish prosecutors filed charges on 31 January 2008 against Fredrik Neij, Gottfrid Svartholm, and Peter Sunde, who ran the site; and Carl Lundström, a Swedish businessman who through his businesses sold services to the site. The prosecutor claimed the four worked together to administer, host, and develop the site and thereby facilitated other people's breach of copyright law. Some 34 cases of copyright infringements were originally listed, of which 21 were related to music files, 9 to movies, and 4 to games. One case involving music files w ...

The Pirate Bay
The Pirate Bay (sometimes abbreviated as TPB) is an online index of digital content of entertainment media and software. Founded in 2003 by Swedish think tank Piratbyrån, The Pirate Bay allows visitors to search, download, and contribute magnet links and torrent files, which facilitate peer-to-peer, file sharing among users of the BitTorrent protocol. The Pirate Bay has sparked controversies and discussion about legal aspects of file sharing, copyright, and civil liberties and has become a platform for political initiatives against established intellectual property laws as well as a central figure in an anti-copyright movement. The website has faced several shutdowns and domain seizures, switching to a series of new web addresses to continue operating. In April 2009, the website's founders (Peter Sunde, Fredrik Neij, and Gottfrid Svartholm) were found guilty in the Pirate Bay trial in Sweden for assisting in copyright infringement and were sentenced to serve one year in pri ...

Megaupload Legal Case
The Megaupload legal case concerns a number of related criminal indictments and enforcement actions taken against Megaupload owner Kim Dotcom in various jurisdictions. On 19 January 2012 the United States Department of Justice seized and shut down the file-hosting site Megaupload.com and commenced criminal cases against its owners and others. On 20 January 2012 Hong Kong Customs froze more than 300 million Hong Kong dollars (US$39 million) in assets belonging to the company. Arrests in New Zealand Acting upon a US Federal prosecutor's request, the New Zealand Police arrested Dotcom and three other Megaupload executives in a leased $30 million mansion at Coatesville near Auckland on Friday, 20 January 2012 (NZDT, UTC+13). This was pursuant to a request from the U.S. Federal Bureau of Investigation that the four be extradited for racketeering and money laundering. The raid was timed for the birthday celebration of Dotcom. Assets worth $17 million including art works and cars were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motion Picture Association Of America
The Motion Picture Association (MPA) is an American trade association representing the five major film studios of the United States, as well as the video streaming service Netflix. Founded in 1922 as the Motion Picture Producers and Distributors of America (MPPDA) and known as the Motion Picture Association of America (MPAA) from 1945 until September 2019, its original goal was to ensure the viability of the American film industry. In addition, the MPA established guidelines for film content which resulted in the creation of the Motion Picture Production Code in 1930. This code, also known as the Hays Code, was replaced by a voluntary film rating system in 1968, which is managed by the Classification and Rating Administration (CARA). The MPA has advocated for the motion picture and television industry, with the goals of promoting effective copyright protection, reducing piracy, and expanding market access. It has worked to curb copyright infringement, including attempts to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pirated
Copyright infringement (at times referred to as piracy) is the use of works protected by copyright without permission for a usage where such permission is required, thereby infringing certain exclusive rights granted to the copyright holder, such as the right to reproduce, distribute, display or perform the protected work, or to make derivative works. The copyright holder is typically the work's creator, or a publisher or other business to whom copyright has been assigned. Copyright holders routinely invoke legal and technological measures to prevent and penalize copyright infringement. Copyright infringement disputes are usually resolved through direct negotiation, a notice and take down process, or litigation in civil court. Egregious or large-scale commercial infringement, especially when it involves counterfeiting, is sometimes prosecuted via the criminal justice system. Shifting public expectations, advances in digital technology and the increasing reach of the Internet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Energy Consumption
Electric energy consumption is the form of energy consumption that uses electrical energy. Electric energy consumption is the actual energy demand made on existing electricity supply for transportation, residential, industrial, commercial, and other miscellaneous purposes. Global electricity consumption in 2019 was 22,848 terawatt-hour (TWh), about 135% more than the amount of consumption in 1990 (9,702 TWh). China, United States, and India accounted for over 50% of the global share of electricity consumption. Overview Electric energy is most often measured either in joules (J), or in watt hours (W·h). : 1 W·s = 1 J : 1 W·h = 3600 W·s = 3600 J Electric and electronic devices consume electric energy to generate desired output (i.e., light, heat, motion, etc.). During operation, some part of the energy is lost depending on the electrical efficiency. Electricity has been generated in power stations since 1882. The invention of the steam turbine in 1884 to drive the electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inter-domain
Inter-domain routing is data flow control and interaction between Primary Domain Controller (PDC) computers. This type of computer uses various computer protocols and services to operate. It is most commonly used to multicast between internet domains. Internet use An Internet service provider, ISP, is provided with a unique URL access address. This address is a unique number. The number for each ISP is stored within a DNS server. The DNS servers interpret the ISP URL Domain name and provide the appropriate IP address number. The Domain is under the control of a specialized computer, called a PDC, (primary domain controller). This computer holds records of all the user accounts within the domain, their rights to access information, and lists of approved System Operatives. This PDC is backed up by an SDC, (a secondary domain controller), this computer synchronises itself with the PDC and takes over the role in the event of a PDC failure. Multiple replication servers connect to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
