A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [2] [3] [4] A router is connected to two or more data lines from different IP networks.
A wireless router or Wi-Fi router is a device that performs the functions of a router and also includes the functions of a wireless access point.

A core router is a router designed to operate in the Internet backbone, or core. To fulfill this role, a router must be able to support multiple telecommunications interfaces of the highest speed in use in the core Internet and must be able to forward IP packets at full speed on all of them. It must also support the routing protocols being used ...
In computer networking, the ICMP Internet Router Discovery Protocol ( IRDP ), also called the Internet Router Discovery Protocol, [1] is a protocol for computer hosts to discover the presence and location of routers on their IPv4 local area network. Router discovery is useful for accessing computer systems on other nonlocal area networks. [2]
Hop (networking) An illustration of hops in a wired network (assuming a 0-origin hop count [1] ). The hop count between the computers in this case is 2. In wired computer networking a hop occurs when a packet is passed from one network segment to the next. Data packets pass through routers as they travel between source and destination.
