Abstract

If the learning content is delivered or enabled by means of electronic technology then it is known as E-Learning. E-Learning System is of two types: [i] synchronous and [ii] asynchronous. These two terms refer to “the extent to which a course is bound by place and/or time”. Synchronous means that two or more events occur at the same time. Here, synchronous means the E-Learning System that is led by instructor/teacher. Asynchronous means that two or more events don't occur at the same time. E-Learning can occur in and out of the class room. E-Learning is the effective learning process. Hence, it becomes a promising paradigm in education. The effectiveness of this system makes us to consider the „e? in E-Learning, which stands for Electronic, to represent „Effective?. Some important characteristics of E-Learning System can be listed as: Interaction, Personalization, Adaptation, Intelligence, Interoperability, Accessibility and Security. The architecture for E-Learning System which posses the above mentioned characteristics consists of various components or layers for supporting instructional design, for retrieving relevant learning materials, for processing and analyzing data to enable meaningful E-Learning recommendations to instructors and learners. This paper deals with the existing architecture of E-Learning, the need of semantic knowledge, Interaction Layer and the practical usability of such system.
