# Network fundamentals
|
|
|
|
> A network is a system that allows computing devices to communicate and
|
|
> exchange information with each other.
|
|
|
|
In order for devices to be able to communicate they must share a common
|
|
**communication protocol**.
|
|
|
|
A protocol specifies **rules determining how information is to be exchanged**.
|
|
(Simply connecting two devices is not sufficient for them to be able to
|
|
communicate, they must have a shared language.)
|
|
|
|
The nodes of a network are called [hosts](Network_hosts.md).
