Zoom is a remote conferencing service (read more about it here) that combines video conferencing, online meetings, chat, and mobile collaboration. It can be used for meetings, conferences, chats, and webinars using video conferencing (video and audio) or tele conferencing (audio only). It offers a full-featured basic plan that you can use for FREE (no trial period). It is available for use with Windows, Mac, iOS, and Android.
What devices can I use? You can use Zoom on a home or office computer, laptop, tablet, or smart phone. If your device has a webcam (camera) and microphone, you can join a Zoom and enjoy video and audio. Even if you don't have a webcam/camera but do have a microphone, you can still join Zoom and enjoy the audio.
Do I need to subscribe to Zoom to join a meeting or view a presentation? No. A Zoom account isn't required to attend a meeting or view a conference. (You only need an account if you wish to host a meeting of your own.)
What is Zoom etiquette? When joining a Zoom meeting or conference, it's good to be aware of your video and audio settings. Are you visible to others? Can they hear what you're saying?
When you join a meeting, you can "Join with Video (includes audio)" or "Join with Audio (no video)." Check the icons in the Zoom Meeting menu bar (hold you cursor over the meeting window and it should pop up). Zoom allows you to turn video and audio off and on. For example, to unmute yourself and begin talking, click on the Unmute button (microphone) in the bottom-left corner. To mute yourself, click the Mute button (microphone) and a red slash will appear indicating your audio is off (but you can still hear others talking).
