EDonkey networkThe eDonkey Network (also known as the eDonkey2000 network or eD2k) is a decentralized, mostly server-based, network created in 2000 by US developers Jed McCaleb and Sam Yagan that is best suited to share big files among users, and to provide long term availability of files. Like most sharing networks, it is decentralized, as there is no central hub for the network; also, files are not stored on a central server but are exchanged directly between users based on the peer-to-peer principle.
Réseau socialEn sciences humaines et sociales, l'expression réseau social désigne un agencement de liens entre des individus ou des organisations, constituant un groupement qui a un sens : la famille, les collègues, un groupe d'amis, une communauté, etc. L'anthropologue australien John Arundel Barnes a introduit l'expression en 1954. L'analyse des réseaux sociaux est devenue une spécialité universitaire dans le champ de la sociologie, se fondant sur la théorie des réseaux et l'usage des graphes.
Interdependent networksThe study of interdependent networks is a subfield of network science dealing with phenomena caused by the interactions between complex networks. Though there may be a wide variety of interactions between networks, dependency focuses on the scenario in which the nodes in one network require support from nodes in another network. In nature, networks rarely appear in isolation. They are typically elements in larger systems and can have non-trivial effects on one another.
