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.

Protocols are rules (or languages) that govern how devices on a network communicate with each other.

| LAN | Printer | Ethernet cable | TCP/IP, Bonjour |
| LAN | Ethernet switch | Ethernet cable | IEEE ... |
