In the contemporary academic landscape, online education has transitioned from a niche alternative for adult learners to a primary mode of instruction for millions of students globally. This shift is driven by the convergence of high-speed internet access, the proliferation of mobile devices, and a growing demand for flexible, lifelong learning opportunities.
