E-learning includes all forms of electronically supported learning and teaching. Whether online learning or not, information and communication system is a specific medium to implement the learning process. Even with the continuous improvement of equipment and courses, the term is still most likely to be used to refer to the e-education experience in and out of the classroom through technology.

E-learning is essentially the transfer of skills and knowledge through computers and networks. E-learning applications and processes include network-based learning, computer-based learning, virtual educational opportunities and digital collaboration. Content is transmitted through Internet, intranet/extranet, audio or video tape, satellite TV and CD-ROM. It can be self-paced or directed by teachers, including text, images, animation, streaming media, video and audio.

E-learning is a good choice in education, especially when there are obstacles in the traditional learning environment. For example, some people want to continue their education, but they don't live within the driving distance of a college or university, and think it is not feasible to move. For these students, e-learning is a feasible choice. Another obstacle to traditional learning, especially in grades K to 12, is the "one size fits all" mentality it embraces. Many students can't study well in the traditional learning environment, but they can thrive in a more flexible environment. In order to solve this problem, parents began to look for e-learning opportunities for their children. Some people choose full-time registration in virtual schools, while others use e-learning to supplement home school courses. In the business field, e-learning provides a way for companies to train and guide their employees without going to a central location.

Convenience is one of the main advantages of e-learning. It allows students to work and study at their own pace, without being limited by the time of traditional study. Because e-learning provides opportunities to access learning materials at any time, students can flexibly arrange their family, work and other activities. Another major benefit of e-learning is the accessibility it provides. Students can study anywhere in the world. This is a particularly important consideration for students who want to study in another country. In addition, because e-learning can be done at home, students have less clothing and driving expenses than traditional learning.
