             1.2 The Emergence of Tele-education
             Radical changes in the computing infrastructure, spurred by multimedia computing and communication, will do more than extend the educational system, that is revolutionize it. Technological advances will make classrooms mush more accessible and effective. Today, classroom education dominates instruction from elementary school to graduate school. This method has remained popular for a very long time and will probably persist as the most common mode of education. However, classroom education has its problems, that is the effectiveness decline with increase in the number of students per class. Other pressures affect the instructors, many of whom are not experts in the material they must teach, are not good ‘performers’ in class, or simply are not interested in teaching.

This essentially requires all students and the instructors to collect in one spot for their specified period. But with the emerging technology, these problems can be overcome.
             1.3 Reasons for studying Tele-education
             The current Tele-education systems that have been applied in some countries are generally of multipoint transmission technique. It is found that, this kind of transmission technique having several problems or defects. Mostly, problems raised during the application of the system. One of the significant problems raised is that, for the multipoint transmission, the signals or information transmitted by the sender do not completely received by the receiver. This problem is might be due to error that occurs during the transmission of the signals or information. Another problem is lag of transmission. For this case, the signals or information transmitted do not arrive at all the receiver at the same time, for example, the question raised by the lecturer might not received by the ...
