A router is a networking device that forwards data packets between computer networks). It performs the traffic directing functions between networks and on the global Internet. Routers can be built from standard computer parts but are mostly specialized purpose-built computers). They guide and direct network data, using packets that contain various kinds of data such as files, communications, and simple transmissions like web interactions. Routers can also provide security by using embedded firewall and content filtering software to provide additional protection from unwanted content and malicious websites without affecting your online experience.
A router connects two or more packet-switched networks and allows multiple devices to use the same Internet. It is positioned where two or more networks meet at each point of presence on the internet. Routers can be distinguished on the basis of the network in which they operate. A router in a local area network (LAN) of a single organization is called an interior router. A router that is operated in the Internet backbone is described as an exterior router. A router that connects a LAN with the Internet or a wide area network (WAN) is called a border router or gateway router).
A router is a gateway that passes data between one or more local area networks (LANs) . Access routers connect subscribers to their provider’s network so they can reach the Internet or private networks. Wireless and wired access routers support these networks to enable compute devices to connect to Wi-Fi and Ethernet LANs. A router can broadcast a wireless signal (Wi-Fi) to connected and enabled devices, but it isn’t only for Wi-Fi. Routers also offer hard-wired connections to the Internet. Once the router connects to Internet data through hard wire or Ethernet, it can then translate that connection into a transmittable Wi-Fi signal that capable devices can pick up. You can also hard-wire your computer into the router and use it for a wired Internet link.
In summary, a router is a device that connects two or more packet-switched networks and forwards data packets between them. It is a common tool for modern network computing and allows multiple devices to use the same Internet. Routers can provide security and can be distinguished on the basis of the network in which they operate. Access routers connect subscribers to their provider’s network so they can reach the Internet or private networks.
