UPnP, or Universal Plug and Play, is a set of networking protocols that allows devices on a local network to discover and communicate with each other seamlessly. It enables devices like printers, cameras, and smart TVs to connect without requiring complex configuration, making it user-friendly for home networks. One of the key features of UPnP is its ability to automatically configure network settings, such as port forwarding, which is essential for applications like online gaming and video streaming. This simplifies the process for users, allowing them to enjoy their devices without needing extensive technical knowledge.
