Broadband routers, at their core, are used to provide internet access for multiple users. The majority of broadband routers on the market feature a network switch that features at least four Ethernet ports. These are used for computer connections, and will work with desktops and laptops.

Routers are connected to at least two computer networks, and they are used to receive and forward data packets between those networks. Routers can work in conjunction with LANs (local area networks) or WANs (wide area networks). Typically, a LAN will serve a solitary office or a single floor on a building, while a WAN will consist of interconnected LANs or PCs that are spread out between buildings, cities, states, or even countries. It is possible to find an effective router that suits your specific needs, whether you need to connect LANs, WANs, or a LAN to an internet service provider’s network.

Routers use headers and forwarding tables in order to construct the best path for forwarding data packets between two or more computer networks. There are protocols in place such as the basic Internet protocol (IP), the transmission control protocol (TCP), and the internet control message protocol (ICMP) that allow for communication and enable routers to configure efficient data trails. Protocols such as these can be used to transfer information between all networks that are interconnected. They are effective with LAN (local area network) and WAN (wide area network) communications.
