Key advantages of E-learning are flexibility and the ability to work at any place where an internet connection is available and at one's own pace. E-classes are asynchronous which allows learners to participate and complete coursework in accordance with their daily commitments. This makes an E-learning education a viable option for those that have other commitments such as family or work or cannot participate easily e.g. depending on a disablility. There are also transportation cost (and time) benefits with not having to commute to and from campus.
Computer Based Learning, sometimes abbreviated CBL, refers to the use of computers as a key component of the educational environment. While this can refer to the use of computers in a classroom, the term more broadly refers to a structured environment in which computers are used for teaching purposes. The concept is generally seen as being distinct from the use of computers in ways where learning is at least a peripheral element of the experience.
