A router is a computer networking device which forwards data packets at the junction of two or more networks.

Example

For example, say a household has a series of computers connected to each other on a LAN, and a single connection to the Internet through an ISP. A router can be used to connect the house's LAN with the Internet, giving each device Internet access.

Relation to other networking technologies

• Many consumer routers also act as DHCP servers, assigning IP addresses to network devices.
• Routers are often confused with switch, but serve very different functions on a network. See Routers vs. Switches for more information.
