router(computing)
A router[a] 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.[1]
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. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. This creates an overlay internetwork.
The most familiar type of routers are home and small office routers that simply pass data, such as web pages, email, IM, and videos between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an ISP. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
router(wood working)
A router (/ˈraʊtə/, also /-ər/) is a tool used to rout out (hollow out) an area in the face of a relatively hard workpiece, typically of wood or plastic. The main application of routers is in woodworking, especially cabinetry. The router is most commonly used as a plunging tool and also inverted in a router table.
The hand tool form of router is the original form. It is a specialized type of hand plane with a broad base and a narrow blade projecting well beyond its base plate (gaining it the nickname old woman's tooth). Today the power tool form of router, with an electric-motor-driven spindle, is the more common form, and the hand tool is now often called a router plane. Although the hand tool has a few advantages over the power tool and retains favour with some workers, it has been mostly replaced by the modern spindle router, which was designed for the same work. Some workers consider it to be the single most versatile woodworking power tool.[1] Becoming more popular is the use of a CNC wood router, which implements the advantages of CNC (Computer Numerical Control).
Related to the router is a smaller, lighter version designed specifically for trimming laminates. It can be used for smaller general routing work. For example, with an appropriate jig it can be used for recessing door hinges and recessing lock faceplates. Even rotary tools can be used as routers when the right bits and accessories (such as a plastic router base) are attached.
