Although the impact of the Internet on a particular child differ according to the nature of each child and how the child uses the Internet, adults also need to provide a basic grasp of these general potentialities. The temperament and psychological criteria of a child often eventually change the impact of the Internet over him or her. Without being directed and supervised by their parents and teachers, many of the children may have accessed the Internet. That makes them vulnerable to the Internet's harmful impacts. It is quite important for parents to track their child's actions and relationships and to ensure a better use of the Internet.
