A ‘webinar’ is a seminar or workshop conducted over the Internet. It typically involves live presentations, lectures, or discussions delivered via video conferencing software or webinar platforms. Webinars allow participants to join remotely from anywhere with an internet connection, making them convenient and accessible to a wide audience. 

They are often used for educational, training, marketing, or informational purposes by businesses, educational institutions, nonprofit organizations, and other entities.

During a webinar, participants can interact with the presenter or each other through features like live chat, Q&A sessions, polls, and surveys. Webinars can be recorded for later viewing or shared with those unable to attend the live session.
