What is online education definition? Online education, often identified as E-learning, in most cases refers to a course, program or degree delivered completely online. Actually, four general categories of definitions were identified: 1) technology-driven, 2) delivery-system-oriented, 3) communication-oriented, and 4) educational-paradigm-oriented. 
Broad e-learning definition is the use of various electronic media (computers, tablets, or phones) to educate or train learners. E-learning actually refers to use of electronic applications and processes to learn. E-learning applications and processes include Web-based learning, computer-based learning, virtual classrooms and digital collaboration. Content can be delivered via the Internet, intranet/extranet, audio or video tape, satellite TV and CD-ROM

The Impact of E-Learning
While e-learning has become the primary form of distance education, it is also transforming instruction on campus. Higher education historically is a campus-based institution. Many students live on campus for the duration of their studies; others live near campus and commute to campus to take classes and to receive campus-based support services. This physical connection has defined the relationship between the student and the institution. It has also helped to shape the curriculum itself. E-learning has blurred these traditional relationships, removing geography as a defining element in the student-institution relationship. 
Disadvantages of online education
Before enrolling, you should also consider some disadvantages of online education:
1. E – learning course could lack accreditation
It is always a good idea to check if the online course you are interested in has its program accredited. Legitimate schools are proud of their status with accrediting agencies, and agencies are happy to accredit good schools so this information shouldn’t be hard to find.
If you earn a degree from a school with no accreditation, it can be worthless and could leave you in debt. However, this doesn’t necessarily mean you won’t learn anything, but if getting a degree is your main object, please do check. Verifying an online program’s accreditation is something that can save you time, money and heartache in the long run. 
2. E – learning course could provide low quality education
Even if online course is accredited, that doesn’t necessarily mean you’ll get your money’s worth or time you invest would be time well spent. Use a search engine to find out all of the details about the specific online course. Dig the Internet, you will find the information that could help you make a final decision on whether or not you should enroll.
3. Face-to-face interaction
There is often a tendency to underestimate the impact of never meeting the instructor and other students in the class. Building relationships with your instructor and classmates will require more effort in an online environment than in a brick and mortar school.
4. More work and self discipline
Online courses typically require a greater amount of reading and assignments than traditional classes. Programs in general are improving the quality of their online courses, and this means that students will have to do more to prove that they’ve mastered the material. Also, online courses usually have deadlines for assignments, quizzes or tests. This requires a lot of self discipline in order to deal with the schedule.
Despite the disadvantages outlined above, you should not be discouraged to enroll in an online course. Here is the list of 10 reasons why eLearning is essential for students. Change your life to the better, try out an online course.
