End devices are the final points of communication in a network. They include devices like computers, smartphones, tablets, and printers that connect to a network to send or receive data. These devices are essential for users to access services and information over the internet or local networks. In a typical network setup, end devices communicate through network switches and routers to reach other devices or the internet. They can be wired or wireless, depending on the technology used. Proper configuration and security measures are important to ensure that end devices function effectively and safely within the network.
