**4.3 In virtual environments, the place of learning is a network based on interactive communication**

In environments based on e-learning, the learning environment is such that people can freely communicate with different communication groups, and this communication knows no boundaries, and even by using social networks, it is possible to communicate with experts and professors abroad [35]. In general, the main foundation of using e-learning environments is to communicate with different people inside and outside the country, which can be achieved by using video meetings and other communication tools of social networks. Therefore, it is necessary for the lecturer to make multichannel communication as the basis of his teaching approaches and, accordingly, help the students to deepen their informal learning.
