Role of Routers in Networking
Before we examine into the world of routers, you need to understand what a broadband connection is and how it works. Broadband is a high-speed, high-capacity broadcast medium that can carry signals from multiple independent network carriers. Broadband technology can support a wide range of frequencies. It is used to transmit data, voice and video over long distances at the same time. Routers take information that arrives through your broadband signal via a modem, decode it, and deliver it to your computer. The router will also choose the best route for the data packet so that you receive the information quickly. Router is a device that forward data packets along networks. It is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP network. Routers operate at the network layer (OSI Model's layer 3). The main function of a router is to connect networks together and keep certain kinds of broadcast traffic under control. Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols such as ICMP to communicate with each other and configure the best route between any two hosts. Many different types of routers have been developed so that the information coming over your broadband connection can be sent to a variety of different receivers including your computer, your phone, and others. Generally, Routers that we used can either be Wired or Wireless. A wired router will normally connect to your computer and computers or hardware through an Ethernet cable. This happens with the use of output ports and the only input port provided on a router will be used for the internet. A Wifi router may allow access from several computers through wired Ethernet cables and through wireless connections. You will know the router you are using is wireless if it comes with an antenna. The antenna will provide the router with a specific range that allows other computer in the area with wireless capabilities to access the router if they have password access.
