E-learning involves using electronic devices like computers and mobile phones to provide educational content. It can take various forms like web-based learning, online learning, and virtual education. E-learning uses technologies like the internet, intranets, smart devices, and multimedia content. Historically, e-learning began in the 1960s with computer-based math and reading instruction and has since expanded with developments like online courses and virtual classrooms. In India, initiatives like IGNOU, NPTEL, and programs from universities have helped establish e-learning. E-learning can be traditional with highly produced web courses or rapid e-learning with quickly produced content and can be asynchronous or synchronous.
