It is an incomplete computer network without a router. So, what all it does within a network. A router actually transfers data packets along networks. It requires at least two networks for a router to connect, commonly it connects two LANs or WANs or a LAN and its ISP network. As a connecter device, routers are positioned at gateways, where two or more networks are connected.
Routing in the Internet
Routing is the technique using which data get its transfer path from one host computer to another. To say technically, routers uses headers and tables to determine the best path for transferring data packets among networks, and for this they use protocols such as ICMP to communicate with one other and thus configures the best route between any two hosts.
Difference between Routers, Switches and Hubs
Many people understand routers, switches and hubs for one another beside their different type of functionalities.
Today most routers are integrated into a single device having the features of a router, switch and hub. Still a router, switch and a hub are all quite different from one another, even after integrating all into a single device.
A switch and hub are two devices, which do similar task on a network. Both serves to be as a central part of your network and transfers data, which are known as frames. A transferred frame from a computer is received and improved to transmit it to the port of the destination computer. The difference here between these two devices is in the way by which frames are transferred.
On another side, routers are completely different from a switch or hub. Where a hub or switch job is to transmit frames, a router role is to route the data packets to other networks where its task is to submit the data packet to its destination ultimately. The major difference here of the data packet is that it contains destination address together with the data, which guides it to its destination.
All routers have a port to connect to a DSL or Cable modem and the integrated switch facilitate users to create a LAN. This makes possibility for the computers on a LAN to connect to the Internet.
