A social networking service is an online
service, platform, or site that focuses on facilitating the building
of social networks or social
relations among people who, for example, share interests,
activities, backgrounds, or real-life connections. A social network service
consists of a representation of each user (often a profile), his/her social
links, and a variety of additional services. Most social network services are web-based and provide means for users to interact over the Internet, such as e-mail and instant
messaging. Online
community services are sometimes considered as a social network
service, though in a broader sense, social network service usually means an
individual-centered service whereas online
community services are group-centered. Social networking sites
allow users to share ideas, activities, events, and interests within their
individual networks.Like -
