**Physical Connection**

A “physical connection” refers to the tangible, hardware-based link between devices or components in a network or system. In the context of technology and computing, it typically involves cables, connectors, ports, or other physical mediums that enable data transfer, communication, or power transmission. Physical connections are essential for establishing reliable and secure interactions between devices, such as Ethernet cables linking computers to routers, USB cables connecting peripherals, or fiber optic lines transmitting internet signals. Understanding physical connections helps optimize network performance, troubleshoot connectivity issues, and ensures the proper setup of hardware infrastructure.
