E-learning as a network of sharing knowledge has changed dramatically the traditional concept of learning. To develop and implement a successful elearning system, it is vital that institutions recognize the success factors of e-learning systems. This study reviewed the success factors and identified the most important technological aspects of e-learning. Elearning technological aspects were described and grouped into six categories, which are ease of access, interface design, level of interaction, system quality, service quality, and internet quality. A survey instrument incorporating these aspects was developed and was pilot-tested on a sample of thirty students. The results from the pilot study revealed that the survey instrument is highly reliable and thus would be useful to researchers who intend to develop and implement e-learning systems.
