ZOOM is a video conferencing app that allows multiple participants to join meetings and share screens, audio, and video. Key features include HD video conferencing, screen sharing, annotation tools, and meetings of up to 100 people. The manual provides instructions for setting up a free ZOOM account, downloading clients, joining and hosting meetings, sharing screens, and using chat functions on Windows and Android platforms. Free basic accounts limit meetings with 3 or more people to 40 minutes. Paid professional, business, and enterprise plans unlock additional features and remove meeting time limits.
