Case studies also attempt to understand the varicose situation by creating study literature tailored to the actual situation.  With the advent of commuters and the internet, as well as the advancement in photography, it is possible to create a country of audio-visual labor that seems to have created a real reality on the commuter screen. 

The teacher and the student do not meet directly, the two can interact indirectly through a commuter network.  From the above discussion it is clear that this is a multi-way teaching-learning process, as everyone involved can interact with each other.  Everyone’s commuter connected to a virtual classroom is connected to a central server (commuter).  This server receives and distributes information from each person The outline of the virtual classroom can be shown in the figure below.n virtually.

This illusion is now virtual Classroom means a classroom, a concept: a group of students geographically in one place or in different locations, an interconnected information technology-based system where teaching and learning can be done through multidisciplinary live interactions.  IT  The oriented approach does not involve teacher-student interaction between a single fixed four wall, but teacher-student interaction through a commuter network.

Anyone can interact with anyone.  When the teacher or subject matter expert is making a presentation, other students listen and watch it.  Individuals associated with the server can talk to each other.  Students listen and watch as the teacher introduces.  

Other students listen when the teacher and students interact.  While the discussion is going on, other students can meet each other in the discussion and present their own questions.  Thus this is a multidisciplinary study-teaching process.  It is up to the teacher to decide the role of the subject matter expert in this process.  Although the subject matter expert is not involved in this approach, the teaching-learning process can be done easily.  How many areas can be covered by this approach depends on which computer network or computerized network is used 4.

Audio Conferencing: The process of exchanging information between teacher and student is very important in synchronous learning.  Audio conferencing is also a technique used in online learning for actual interaction between teacher and student.  

The beginning of audio conferencing can be called the first step when the listener or student can contact the radio broadcasting center with the help of any means of communication during the educational programs broadcast on the radio and ask their problem or question which reaches everyone participating in the entire live broadcast.
