Answer:
router
Step-by-step explanation:
A "router" is a hardware/networking device that is used in order to forward a formatted unit of data that is carried by a network (packet-switched) between computer networks.
The formatted unit of data is called "data packets." This is the form of the data when a person sends another person an email and the like. Such process is known as "routing."
Clearly, the statement above refers to the "router" device.
