Computing Network: a group of interconnected computing devices capable of sending or receiving data.

Path: the series of connections between computing devices on a network starting with a sender and ending with a receiver.

Bandwidth: the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.

Redundancy: 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.

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