A social networking site is any site that has a public or semi-public profile page, including dating sites, fan sites and so on. A social media site has profiles and connections, combined with the tools to easily share online content of all types.

An online social network is a website where groups of Internet users can meet, communicate (typically via chats or online calls), share and create content, react to this content and build own digital network of contacts. Starting your path in web app development, it is crucial to choose the type of social network.
