e-Learning is learning that is supported by appropriate technology.  It allows you to learn anywhere at any time, as long as you have a properly configured computer. E-learning can be CD-ROM-based, Network-based, Intranet-based or Internet-based. It can include text, video, audio, animation and virtual environments. It can be a very rich learning experience that can be even more engaging and effective than the training you might experience in a crowded classroom. It's self-paced, hands-on learning

The quality of the technology-based training, as in every form of training, is in its content and its delivery. E-learning can suffer from many of the same pitfalls as classroom training, such as boring slides, monotonous speech, and little opportunity for interaction. The beauty of e-learning, however, is that great instructional designers and web developers allow the creation of very effective learning environments that can absorb learners and engage them in the learning activities and materials.
