Thing 8 on Screencasting and Screen Sharing tools has been posted. Screencasting tools record whatever is happening on your computer or mobile device screen and let you record a voice narration as well. When you’re done recording, you end up with a video. What you can do with the video depends on the tool you used, but most common options include uploading to YouTube, dowloading to you computer or embedding on a website. Screen sharing tools don’t record your screen activities, they’re more like a live meeting where you’re sharing your screen with a limited group of people.
