This paper will talk all about advantages of Online Learning. Which Online learning (also known as electronic learning or e-learning) is the result of teaching delivered electronically using computer-based media. The material is frequently accessed via a network, including websites, the internet, intranets, CDs and DVDs. E-learning not only accesses information (eg, putting up web pages), but also helps learners with specific results (eg achieving goals). In addition to delivering e-learning teaching, it can monitor student performance and report student progress.
