Home Wi-Fi Network:

Devices Connect: Your smartphone, laptop, and smart TV connect to your home router wirelessly.
Router Manages Traffic: The router directs internet traffic between your devices and your internet service provider (ISP).
Data Transmission: When you stream a video, your smart TV sends a request to the router, which forwards it to the ISP, retrieves the video data from the internet, and sends it back to your TV.
Network Protocols: Communication is managed by network protocols like TCP/IP, ensuring data is sent and received correctly and efficiently.
