As opposed to the computer-based training of the 1980s, the term e-learning is most frequently used to refer to computer-based training which incorporates technologies that support interactivity beyond what would be provided by a single personal computer. E-learning, therefore, is an approach to facilitate and enhance learning through both computer and communication technologies. Such devices can include personal computers, CD-ROM, digital television, PDA, and mobile phones. Communication technologies enable the use of the Internet, e-mail, discussion forums, collaborative software, classroom management software, and team learning systems.
