A city network is a system of computers and infrastructure in a city that allow people living there to easily communicate with each other, access online services, and use the internet. It works like a big web of wires, antennas, and other hardware, all connected together and sending data back and forth. People in the city can use the city network to share information, communicate, shop, watch movies and shows, and more. The city network is like a big computer network, but it's specifically designed for a city, making it easier to connect people and businesses together and give them access to the internet.
