The world of the 21st century is dominated by digital technology. In this age of information and technology, online educational approaches are continuously expanding. Online education is becoming increasingly popular in India due to universities and colleges digitizing, internet penetration and student demand. RedSeer Consulting predicts that India's online education market (especially higher education and lifelong learning) will reach 5 billion U.S. dollars by 2025, driven by the government's focus on designing online education programs, strengthening digital infrastructure and meeting students' rising demand for upskilling. Numerous innovative technologies and strategies transform the entire educational system. Today, online education is extremely popular and its popularity is developing rapidly day by day. This trend was further accelerated by covid-19 pandemic. Prior to the pandemic, only a handful of educational institutions around the world truly utilized offline learning techniques. According to UNESCO, when Covid-19 occurred, 98% of the global student population in 191 countries shifted from offline to online learning. Google Classrooms, Zoom, and Microsoft Teams were among the most prominent platforms that enabled this transformation.
