An online meeting that occurs in real time and allows for participants to share their desktop screens live is known as a what?

The term that best describes an online meeting occurring in real time where participants can share their desktop screens live is indeed a webinar. Webinars are designed for a larger audience and often include features such as interactive elements where attendees can ask questions or participate in polls, making them ideal for training sessions, presentations, and discussions on various topics.

Webinars typically facilitate 'one-to-many' communication, where one presenter can reach a large number of participants simultaneously. The capability to share screens allows the presenter to illustrate points with visual aids, such as slides or software demonstrations, enhancing understanding and engagement among participants.

In contrast, a conference generally refers to a formal gathering where multiple sessions may occur, a seminar often implies a smaller, more interactive format focusing on educational or training purpose, and a session can refer to any distinct period of time dedicated to a particular topic or activity within a larger event. Each of these terms has different implications regarding format, scale, and interaction level compared to a webinar.
