The Zoom desktop application is an application that can be downloaded and installed from the Zoom website. It enables you to schedule and join new meetings, and be notified of any upcoming meetings.
When you schedule a Zoom meeting, you have the option of saving it as a calendar event in Google Calendar. You can then invite people to the event which then puts the event on yours and their calendar. The invite email can also be used to retrieve the Zoom login when the meeting occurs.
Breakout rooms are a way to allow attendees to go into separate, private rooms to engage in discussion or work on separate projects. They are then returned to the main Zoom meeting. These are managed by the meeting Host.
You can create and use a poll in Zoom to to ask single answer or multiple choice questions to your attendees. The answers are shown in real time and you can save the results in a report.
Hosts can give hosting or co-hosting duties to other attendees in a meeting. These roles have different capabilities. This document explains how to assign different roles to attendees.
You can record and save a Zoom meeting to your computer or to the Zoom cloud. There are some caveats to this process though. Meetings saved to the Zoom cloud can be linked to for your attendees, but these meetings are only saved for 60 days. This document explains how to handle different versions of the recording.
