社交网络看法的英语作文
A social network is a social structure made up of individuals called "nodes", which are tied by one or more specific types of interdependency, such as friendship, kinship, common interest, financial exchange, dislike, sexual relationships, or relationships of beliefs, knowledge or prestige.
Social Networks are groups of people who share interests and who interact in a variety of ways via software on websites. These include file-sharing, chatting, messaging, exchanging photos/video etc. Social network sites are usually free to join. Include Myspace,Facebook,Bebo,Orkut,LinkedIn and so on.
We define social network sites as web-based services that allow individuals to construct a public or semi-public profile within a bounded system, articulate a list of other users with whom they share a connection, and view and traverse their list of connections and those made by others within the system. The nature and nomenclature of these connections may vary from site to site.
