In this video, we will take a look at communication protocols. Communication protocols are the common rules necessary to reliably exchange data between different devices and networks. In the video, we will explain the differences and points in common between each communication protocol, layered according to its roles, by using the examples of wired LAN, wireless LAN (Wi-Fi), and 4G and 5G mobile communications.
