What a Computer Network Means
Understand the simple idea of two or more devices sharing information.
The Core Idea
A network is just two or more devices connected so they can share information. The moment two phones or laptops can pass data, you have one.
Devices Called Nodes
Any device on a network is a node — a laptop, phone, printer, even a smart thermostat. Two nodes or two million, the relationship is the same.
