Chromecast is a one-of-its-kind of media streaming device. It is all about streaming content either by casting from the mobile or computer to the TV. While doing a presentation or viewing pictures or videos to a group of people, the laptop screen wouldn’t be enough. For a better view, we may want to cast those to a bigger screen like a TV. With Chromecast, we can cast the whole desktop or just a Chrome tab or media files like images, videos, or music to the TV. Casting means sending the contents to the Chromecast-connected TV wirelessly.
