In the nineteenth century, the ever-extending demand for education introduced a new approach as "distance education". It
has received continued developmental changes, and is known as an effective means of communication between a teacher and
learners. Through distance education a learner can follow learning programs without requiring personal contact with or
presence in a training center. This two-way communication system has three major component:
1- trainer,
2- institute (autonomous institution, or mixed institution),
3- instructional materials and aids (publications, electronic devices, human resources, ...)
This paper presents the results of a study on the importance, concepts, characteristics, applications, and different parts of a


distance education system, Finally, a new model of distance education appropriate for personnel training is suggested.
