Distance education allows students to learn remotely without face-to-face interaction with teachers. It has various names like correspondence courses, extension courses, and online education. Advantages include self-paced learning and low costs, while disadvantages are limited interactivity and inability to show motions. Distance education is important in India due to rapid population growth, geographical limitations, and allowing students to work and study simultaneously. Major universities like IGNOU and OUC in India and China use distance education to meet growing demand and help skill development. Future of distance education involves new technologies that provide interactive learning environments and evolving learning management systems to meet learner needs.
