The ''Severe acute respiratory syndrome'' (SARS) Network refers to the system by which the SARS virus managed to have initial seedings in many different geographical locations, with intense but tightly circumscribed activity, without breaking out into an epidemic. ==An Overview of Networks== In the context of network theory a network is graph (network) that uses encodes the components of a system and their interactions. Each component in a system is represented with a node, and their connections between each other are represented with corresponding edges. Networks can be either random or non-random, they may depict complex or simple structures, and their edges may be directed or undirected. Networks are particularly useful in depicting and analyzing complex systems. Networks Examples: *The social network of all professional, friendship, and family ties. *The network describing the interactions between genes, proteins, and metabolites integrate the processes behind living cells. *The network describing which communication devices interact with each other, capturing internet connections or wireless links, is the heart of the modern communication system. *The power grid, a network of generators and transmission lines, supplies with energy virtually all modern technology. 〔 The Network Science Book Project --> iBook --> Page 8 http://barabasilab.neu.edu/networksciencebook/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「The SARS Network」の詳細全文を読む スポンサード リンク
