Distance learning is a method that gives students the opportunity, at various levels (including the acquisition of scientific and technical certificates or special certificates ..., one-to-one courses ...) to complete or part of a distance learning course (from home or from another City or even from another country) without physically attending classes; and ultimately, if they pass the tests, they will be able to benefit from similar privileges as regular students. In this way, all students can continue their education; even those whose work schedule or place of residence prevents them from being present in classrooms.

Today, many of the world's leading universities offer virtual certificates, such as bachelor's, master's, and even doctoral degrees, and these credentials have the same value as regular students' credentials. In the past there was no direct relationship between students and professors in the virtual training courses.

However, with new teaching tools such as the World Wide Web and virtual classes, there is often an interactive relationship between students and prof. And other students. The Benefits of Using Virtual Education for Organizations and Institutions: The most important factor in choosing e-learning is cost-cutting. To this one can call the savings by the abolishment of the costs for lecturers, rent of the classes of instruction, transport costs of the students or accommodation costs. Perhaps the most important factor why large companies and organizations welcome this training method is that their staff attend training courses only for a short time and then return to work.

Another advantage of this method is that the audit and issuance of certificates is automatic, very fast, and inexpensive, so that a student is automatically audited immediately after completing the course; and if he passes this exam, he will be given a diploma.
