an agreed upon set of rules that specify the behavior of some system

the unique number assigned to each device on the internet

a type of computer that forwards data across a network

the inclusion of extra components so that a system can continue to work even if individual components fail, for example by having more than one path between any two connected devices in a network.

can continue to function even in the recent of individual component failures. This is important because elements of complex systems like a computer network fail at unexpected times, often in groups
