Nowadays, users are more addicted to the Online Social Networks(OSNs), a network in which many users, group of people, or a particular organization are connected via network. It ensures communication between these users, or groups or an organizations. Through this communication, the users are able to build connections with other users and share their field of interest, can be able to communicate with other users worldwide.
