Path
is connections between computing devices on a network starting with a sender and ending with a receiver
Bandwidth
is the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second
Copper wire
bits transmitted via electricity
Fiber optic
bits transmitted via light
Wifi
bits transmitted via radio waves
Latency
is the time it takes for a bit to travel from its sender to its receiver
Protocol
is a well known set of rules and standards on how to handle the information

is 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

boolean
is a True or False data type
float
