Distance education, or distance learning, is a field of education that focuses on the pedagogy, technology, and instructional system designs that aim to deliver education to students who are not physically "on site" in a traditional classroom or campus। It has been described as "a process to create and provide access to learning when the source of information and the learners are separated by time and distance, or both." other words, distance learning is the process of creating an educational experience of equal quality for the learner to best suit their needs outside the classroom. Distance education courses that require a physical on-site presence for any reason (including taking examinations) is considered a hybrid or blended course of study. This emerging technology is becoming widely used in universities and institutions around the globe.With the recent trend of technological advance, distance learning is becoming more recognized for its potential in providing individualized attention and communication with students internationally.
