E-learning can be delivered across the internet, intranet, CD,
DVD, or a combination of these technologies. This achieves
the most effective distribution for the course and collection of the
course completion data.
Other considerations are the learning environment that the learner
will complete the course in. Some subjects are better delivered within
a controlled learning environment with facilitators on hand to support
the learning process. Other subjects can be learned effectively sitting
at your desk or at home, even on a train using a laptop or PDA these
days.
