what is a network router
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node.A router is connected to two or more data lines from different networks (as opposed to a network switch, which connects data lines from one single network).When a data packet comes in on one of the lines, the router reads the address information in the packet to determine its ultimate destination. data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. A router is connected to two or more data lines from different networks (as opposed to a network switch, which connects data lines from one single network).
A router (including a wireless router) is a specialized networking device connected to two or more networks running software that allows the router to move data from one network to another. Router functions in an Internet protocol based network operate at the network layer (OSI Model's layer 3). router (including a wireless router) is a specialized networking device connected to two or more networks running software that allows the router to move data from one network to another.
