A streaming device is a small gadget that connects to your TV and allows you to watch movies, shows, and videos over the internet. Popular examples include Roku, Amazon Fire Stick, and Apple TV. These devices make it easy to access various streaming services like Netflix, Hulu, and YouTube without needing a cable subscription. Using a streaming device is simple. You plug it into your TV's HDMI port, connect it to your Wi-Fi, and then use a remote or an app on your phone to browse and select content. This way, you can enjoy your favorite entertainment anytime you want!
