A wired network needs an ethernet cables. They connect to the ethernet port.
Wired - Data is transmitted by copper wires or optical fibres using electrical voltage.
A wireless network does not use wires, it uses wi-fi (radio waves)
Wireless - The wireless adapter in the computer translates the data into a radio signal. An antenna transmits the signal. A wireless router receives the signal.
A mobile network is a communication network. It uses cells, transceivers and then wireless.
Mobile - Data is transmitted by radio waves through a global cellular network. Each cell has a base station. Base stations connect to switching centres. A mobile device has a transmitter and receiver.
