Abstract: Online teaching is the process of educating others via internet.  Various methods can be used, such as one-on-one video calls, group video calls, and webinars. Physical mode teaching means a direct interaction between teachers and students (schools and colleges). Easy access to technological tools have allowed people to experience the new ways to communicate with each other. Traditionally, schools have been the place where students and teachers meet with a handful of books. But things have changed now. People have started adopting technological tools that are effective and user friendly. Virtual classrooms also have some disadvantages such as communication gaps or low internet connection. While many people think that virtual classrooms can never take place in a physical classroom. But the reality is when COVID-19 has affected each one of us, the online classes have helped teachers to complete the syllabus which has not been possible in any other way.  Here in this article, we have done a comparison between Physical and Virtual classrooms.
