Final answer:
The type of physical topology created by connecting all Ethernet cables to a central device is Star Topology. This topology involves connecting all devices to a central switch or hub.
Step-by-step explanation:
The type of physical topology created by connecting all Ethernet cables to a central device is Star Topology. In this topology, all devices are connected to a central hub or switch using Ethernet cables. The central device acts as a main connection point, allowing communication between the connected devices.
For example, in a school network, all computers in a classroom might be connected to a central switch using Ethernet cables. This allows information to flow directly between the computers and the switch, enabling communication and data transfer.
