E-learning, or electronic learning, refers to the use of technology to study and/or do skills training.
Such concept needs a computer or any other device with an internet connection just so data can be transferred between sources.
The biggest benefit of e-learning is that is allows students and/or workers to take their degrees from home or any other place and at a time that best suits their schedule.
It is also cheaper than normal studies as usually books are not required and most of the material is available on web based platforms.
