What is use of router

What is use of router?

A router is a device that forwards data packets along networks. A

router is connected to at least two networks, commonly two LANs or

WANs or a LAN and its ISP's network. Routers are located at

gateways, the places where two or more networks connect, and are

the critical device that keeps data flowing between networks and

keeps the networks connected to the Internet.

A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in 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. 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]

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 modem, 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.

hi,

 Routers use protocols such as Internet control message protocol (ICMP) to communicate with each other in order to update their routing tables and configure the most efficient routes between any two hosts (i.e., computers on the network).

Routing functions were initially performed by general purpose computers, but now they are typically performed by dedicated computers that have been optimized for this purpose. Most Unix-like operating systems include all necessary software to perform routing.

Routers can connect networks using different media and architectures. They do not care about the type of data they handle, and they thus perform very little filtering of data, except for broadcasts.

An edge router is a router that routes data between one or more LANs and the Internet. A core router is a router that transmits data between other routers.

A brouter is a single devices that serves as both a router and a bridge. It will route some packets based on network layer information and forward other packets based on data link layer (i.e., the layer at which bridges operate) information.

Thanks

Hello,

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). The primary function of a router is to connect networks together and keep certain kinds of broadcast traffic under control.

Thanks,
hruthika.
