Device discovery is the process by which a network identifies and locates devices connected to it. This can include computers, smartphones, printers, and other hardware. The goal is to recognize these devices so they can communicate and share resources effectively. During device discovery, protocols like Bonjour or Universal Plug and Play (UPnP) are often used to facilitate the identification of devices. Once discovered, devices can be managed, monitored, and configured, enhancing the overall functionality of the network. This process is essential for maintaining a seamless user experience in both home and business environments.
