What it is?
Routers are minor physical devices that link multiple networks together. To be precise, a router is a Layer 3 gateway device, signifying that it joins two or more networks and that the router works at the network layer of the OSI model.
Home networks typically usage a wireless or wired Internet Protocol (IP) router, IP being the most common OSI network layer protocol. An IP router such as a DSL or cable modem broadband router links the home's local area network (LAN) to the wide-area network (WAN) of the Internet. By preserving configuration information in a section of storage named as the routing table, wired or wireless routers also have the capability to filter traffic, one or the other incoming or outgoing, constructed on the IP addresses of senders and receivers. Some routers permit a network administrator to bring up-to-date the routing table from a Web browser interface. Broadband routers conglomerate the tasks of a router with those of a network switch and a firewall in a single unit.
Routing is the technique of quickening IP packets from one network to another. A router is a device that associates networks together and routes traffic among them..
