File Sharing Networks
File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books. Common methods of storage, transmission and dispersion include removable media, centralized servers on computer networks, Internet-based hyperlinked documents, and the use of distributed peer-to-peer networking. File sharing technologies, such as BitTorrent, are integral to modern media piracy, as well as the sharing of scientific data and other free content. History Files were first exchanged on removable media. Computers were able to access remote files using filesystem mounting, bulletin board systems (1978), Usenet (1979), and FTP servers (1970's). Internet Relay Chat (1988) and Hotline (1997) enabled users to communicate remotely through chat and to exchange files. The mp3 encoding, which was standardized in 1991 and substantially reduced the size of audio files, grew to widespread use in th ...

Digital Media
In mass communication, digital media is any media (communication), communication media that operates in conjunction with various encoded machine-readable data formats. Digital content can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media) and digital broadcasting. ''Digital'' is defined as any data represented by a series of digits, and ''media'' refers to methods of broadcasting or communicating this information. Together, ''digital media'' refers to mediums of digitized information broadcast through a screen and/or a speaker. This also includes text, audio, video, and graphics that are transmitted over the internet for viewing or listening to on the internet. Digital media platforms, such as YouTube, Kick (service), Kick, and Twitch (service), Twitch, accounted for viewership rates of 27.9 billion hours in 2020. A contributing factor to its part in wha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Online Chat
Online chat is any direct text-, audio- or video-based (webcams), one-on-one or one-to-many ( group) chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs or other online games. Online chat includes web-based applications that allow communication – often directly addressed, but anonymous between users in a multi-user environment. Web conferencing is a more specific online service, that is often sold as a service, hosted on a web server controlled by the vendor. Online chat may address point-to-point communications as well as multicast communications from one sender to multiple receivers and voice and video chat, or may be a feature of a web conferencing service. ''Online chat'' in a narrower sense is any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FastTrack
FastTrack is a peer-to-peer (P2P) protocol that was used by the Kazaa, Grokster, iMesh and Morpheus file sharing programs. FastTrack was the most popular file sharing network in 2003, and used mainly for the exchange of music MP3 files. The network had approximately 2.4 million concurrent users in 2003. It is estimated that the total number of users was greater than that of Napster at its peak. History The FastTrack protocol and Kazaa were created and developed by Estonian programmers of BlueMoon Interactive headed by Jaan Tallinn, the same team that later created Skype. After selling it to Niklas Zennström from Sweden and Janus Friis from Denmark, it was introduced in March 2001 by their Dutch company Consumer Empowerment. It appeared during the end of the first generation of P2P networks – Napster shut down in July of that year. There are three FastTrack-based networks, and they use mutually incompatible versions of the protocol. The most popular clients on e ...

Kazaa
Kazaa Media Desktop ( ) (once stylized as "KaZaA", but later usually written "Kazaa") was a peer-to-peer file sharing application using the FastTrack protocol licensed by Joltid Ltd. and operated as Kazaa by Sharman Networks. Kazaa was subsequently under license as a legal music subscription service by Atrinsic, Inc., which lasted until August 2012. Kazaa Media Desktop was commonly used to exchange MP3 music files and other file types, such as videos, applications, and documents over the Internet. The Kazaa Media Desktop client could be downloaded free of charge; however, it was bundled with adware and for a period there were "No spyware" warnings found on Kazaa's website. During the years of Kazaa's operation, Sharman Networks and its business partners and associates were the target of copyright-related lawsuits, related to the content distributed via Kazaa Media Desktop on the FastTrack protocol. By August 2012, the Kazaa website was no longer active. History Kazaa and F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single Point Of Failure
A single point of failure (SPOF) is a part of a system that would Cascading failure, stop the entire system from working if it were to fail. The term single point of failure implies that there is not a backup or redundant option that would enable the system to continue to function without it. SPOFs are undesirable in any system with a goal of high availability or Reliability engineering, reliability, be it a business practice, software application, or other industrial system. If there is a SPOF present in a system, it produces a potential interruption to the system that is substantially more disruptive than an error would elsewhere in the system. Overview Systems can be made robust by adding Redundancy (engineering), redundancy in all potential SPOFs. Redundancy can be achieved at various levels. The assessment of a potential SPOF involves identifying the critical components of a complex system that would provoke a total systems failure in case of wikt:malfunction, malfunction. ...

Freenet
Hyphanet (until mid-2023: Freenet) is a peer-to-peer platform for censorship-resistant, Anonymity application, anonymous communication. It uses a decentralized distributed data store to keep and deliver information, and has a suite of free software for publishing and communicating on the Web without fear of censorship.What is Freenet? , ''Freenet: The Free network official website''.Taylor, Ian J. ''From P2P to Web Services and Grids: Peers in a Client/Server World''. London: Springer, 2005. Both Freenet and some of its associated tools were originally designed by Ian Clarke (computer scientist), Ian Clarke, who defined Freenet's goal as providing freedom of speech on the Internet with strong anonymity protection.

EDonkey2000
eDonkey2000 (nicknamed "ed2k") was a peer-to-peer file sharing application developed by US company MetaMachine ( Jed McCaleb and Sam Yagan), using the Multisource File Transfer Protocol. It supported both the eDonkey2000 network and the Overnet network. On September 28, 2005, eDonkey was discontinued following a cease and desist letter from the RIAA. eDonkey2000 network Users on the eDonkey2000 network predominantly share large files of tens or hundreds of megabytes, such as CD images, videos, games, and software programs. To ease file searching, some websites list the checksums of sought-after files in the form of an ed2k link. Some of those websites also have lists of active servers for users to update. MetaMachines has also created another file-sharing network called Overnet, which interoperates with the eDonkey network, but without the use of servers. Most eDonkey clients also now use the Overnet network. In 2004, MetaMachines announced it would stop development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gnutella
Gnutella is a peer-to-peer network protocol. Founded in 2000, it was the first decentralized peer-to-peer network of its kind, leading to other, later networks adopting the model. In June 2005, Gnutella's population was 1.81 million computers increasing to over three million nodes by January 2006.On the Long-term Evolution of the Two-Tier Gnutella Overlay . Rasti, Stutzbach, Rejaie, 2006. See Figure 2a. In late 2007, it was the most popular file-sharing network on the Internet with an estimated market share of more than 40%. History The first client (also called Gnutella) from which the network got its name was developed by Justin Frankel and Tom Pepper of Nullsoft in early 2000, soon after the company's acquisition by AOL. On March 14, the program was ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
