Network Components

The term network refers to a collection of related things that are interconnected. In a computer network, a node is any computer, printer, or other electronic device that could potentially communicate with another. The connection between these devices, called a link, is any data transmission medium (like wires, infrared waves, or radio waves) shared by a set of nodes and used for communication among the nodes. Protocols are rules (or languages) that govern how devices on a network communicate with each other.

Here are some examples of network components:
