Social Networking is a child of the internet. Internet which was invented so that all the major scientists that worked for CERN from different parts of Europe could stay connected and stay updated with their colleagues’ work. The internet was invented so that communication could become faster and more accessible.

This need gave birth to an invention that is increasingly getting integrated with our daily lives- Computer networks. A network is a structure made up of interconnected hardware components which are used to transmit data; usually the components of the network are capable of communicating with the other components.A network comprises of a server and several nodes. In case of a normal computer network the nodes would be computers or other devices connected to the server but in the case of social networking, the nodes are created virtually on the storage of the server and consist of the details entered by the user. The network topology of social network is made of virtual nodes. A social network is an interface which facilitates this communication by providing a better user interface to the users.

All the links between the nodes on the network are established by the nodes themselves by authenticating the other as a known person, other links are created when the nodes share common personal interests or opinions. The server here acts as the interface and therefore facilitates fast quick communication. Most of these servers enable the nodes to form groups with the others that share either the same interest or recognized by the node as a friend. All other forms of social networking use the same basic structure of social networks and change the interface or use client software as their interface.Due to its increasing popularity on computers, innovation and research in various fields related to social networking was rising and lead to invention of Instant Messaging and Video Conferencing; two very important reasons for the popularity of social networking.
