Social networking is constantly evolving which cater to the needs of the users and help improve its features and user experience. A social network is a tool or a website which allows users to sign up for free and create a personal profile and upload photos of yourself thus creating a web identity which is the reminiscent of your character and attitude. The social networking structure allows users to connect with friends and acquaintances who are also member of the social networking website.
The basic component of any social networking website is its focus on specific region, religious belief or an issue or interest which is supported by likeminded individuals as it deals with connections within friends and acquaintances. Social networks structure in India and elsewhere are structured which help people who want to connect with others who seemed to be far away from each other but still prefer to have a connection anytime. Meeting people online has now increased because of social networking structure but the connection is not just based on coincidence. These are people who need connections with the people other than they already know in real life as there are many aspects in which people around the world connect with each other, like social causes, political issues, or just out of curiosity.
The social networking structure just described is an external form of social network wherein users are free to create profiles and share their profiles with others. There is another form of social networking, namely the internal social networking or ISN, which is usually a small social network which is exclusive in nature and it requires a new user to be recommended first by an existing member of the network to gain approval for access.
There are various mathematical models on which social networking structures of websites in India and abroad are but it is more important that the site is more user friendly rather than based on a complex mathematical model.
