Book excerpt: In the past two decades, the landscape of education has undergone a profound transformation, largely driven by the advent and proliferation of online learning. What was once considered a niche or supplementary method of education has now emerged as a central pillar of the modern educational system. This revolution in online education is not just a shift in the mode of delivery but a fundamental change in how knowledge is disseminated, accessed, and consumed. Online education leverages digital technology to deliver learning experiences through the internet, breaking down traditional barriers such as geography, time constraints, and the limitations of physical resources. This has democratized access to knowledge, allowing students from diverse backgrounds to engage with educational content in ways that were previously unimaginable.
