router n

A router is a device that transfers data packets between computer networks, creating an overlay network. A router is connected to two or more rows of data from various network. When a packet arrives at one of the lines, the router reads the address information in the packet to determine its destination. Use the information in its policy routing table or routing directs the packet to the next network on its journey. Routers perform "TRAFFIC" driving on the Internet. A data packet is typically forwarded by a router to another via the network representing the internal network until it reaches the destination node. [1]

The most common type of routers are home and small office routers that only pass data, such as web pages, email, instant messaging, and video between your computer and the Internet. An example of a modem router is the owner of the cable or DSL modem, which connects to the Internet through an ISP. Router more sophisticated, such as enterprise routers, connect large business or ISP networks of routers powerful heart data at high speed in the front line of fiber optic backbone of the Internet. Although routers are generally dedicated hardware, using software-based router has become increasingly common.
