What is a network?
In the context of computing, a network is a group of devices that communicate with each other, whether by physical cables or wirelessly. Networks range in scale from the connection between your computer and a wireless router to the internet itself.
How does a network work?
When one device is able to exchange data with another device, they are said to be networked together. Connections between devices can be direct or indirect, with any number of nodes between two or more networked devices. A node can be any device on the network that sends, routes, or terminates data, including servers, routers, and computers.
