Advantages and disadvantages of e-learningThe advantages of e-learning is that there is no need to go to school / college. This is a great convenience for teachers and student / student. But e-learning, there are downsides. To do this, the teacher and the pupil / student must have a computer, Web - camera, microphone, and of course the Internet.
