Synchronous e-learning events are the one that takes place in real-time. Synchronous communication requires two people to be present with each other at a particular moment of time. Prime examples of synchronous e-learning are chatting and IM (Instant Messaging), live webcasting, video and audio conference, virtual classrooms, whiteboard, and application sharing, and polling.
Unlike Synchronous e-learning events, Asynchronous events are independent of time. A great example of asynchronous learning is a self-paced course as online learning can be performed at any given place or time. Prime Asynchronous tools consist of e-mail or discussion forums. In these scenarios, students complete the course at their own comfortable pace with the help of a learning program like LMS. Major examples of Asynchronous learning is Audio/Video, Discussion forum, E-mail, Webcasting/Conferencing, Wiki/Blog, Game-based learning, CBT and WBT, Simulations, Self-paced (SCORM).
