13 types of computer networks

A computer network refers to a group of interconnected computing devices that can exchange data and share resources with each other. We can categorize computer networks by their transmission medium, protocols, or the area they cover. By transmission medium, we can roughly classify them into two major networks: wired and wireless networks. If we base on their protocols, there might be many more such as Ethernet networks, token-ring networks, Wi-Fi networks, and mobile phone networks.
Today I will briefly talk about 13 types of computer networks by spatial scope - the area they cover.
