A Webinar (short for web-based seminar) is an online seminar put on by a host, where the participants watch the seminars from their computers.  Typically, they are either watching a Powerpoint presentation, a live demonstration on the internet or an application, or a live video of people.  Normally participants have the ability to interact, including the ability to give, receive and discuss information, rather than just receive it.  Other names for a Webinar include: online seminar, online training, online education, virtual seminar, web seminar, webcast or web conference.
