Step-by-step explanation:
The two common media used in networks are ethernet cables and wireless signals.
Ethernet cables are a type of network cable that allows devices to connect to a network through wired connections. They use twisted pair or fiber optic cables to transmit data.
Wireless signals, on the other hand, use radio waves to transmit data between devices without the need for physical cables. Wi-Fi is a common example of a wireless network that allows devices to connect and communicate with each other.
