| ROUTERS - Computer networking device |

A router is a computer networking device that forwards data packets toward their destinations
through a process known as routing. Routing occurs at layer 3 of the OSI seven-layer model.
Routing is most commonly associated with the Internet Protocol, although other less-popular
routed protocols remain in use.In the original 1960s-era of routing, general-purpose computers
served as routers. Although general-purpose computers can perform routing, modern high-speed
routers are highly specialised computers, generally with extra hardware added to accelerate both
common routing functions such as packet forwarding and specialised functions such as IPsec
encryption .
Other changes also improve reliability, such as using battery rather than mains power, and using
solid-state rather than magnetic storage. Modern routers have thus come to resemble telephone
switches, whose technology they are currently converging with and may eventually replace.
The first modern (dedicated, standalone) routers were the Fuzzball routers.
A router must be connected to at least two networks, or it will have nothing to route. A special
variety of router is the one-armed router used to route packets in a virtual LAN environment. In
the case of a one-armed router the multiple attachments to different networks are all over the
same physical link.
A router which connects end-users to the Internet is called Edge router; A router which serves to
transmit data between other routers is called Core router.A router creates and/or maintains a
table, called a "routing table" that stores the best routes to certain network destinations and
the "routing metrics" associated with those routes.In recent times many routing functions have
been added to LAN switches, creating "Layer 2/3 Switches" which route traffic at near wire speed.
Routers are also now being implemented as Internet gateways, primarily for small networks like
those used in homes and small offices. This application is mainly where the Internet connection
is an always-on broadband connection like cable modem or DSL. These are not "routers" in the true
sense, but the terminology has been confused with network address translation.
