E-learning involves using electronic media and technology for education. It allows for flexible, cost-effective learning across various topics. E-learning can be synchronous, with real-time interaction, or asynchronous through self-paced learning. It provides benefits like improved access and interactions for students, while allowing them to learn at their own pace. However, e-learning also faces disadvantages like potential cheating and lack of social interaction. Successful e-learning projects require alignment with organizational needs, good communication, proper implementation and ongoing support.
