A router can be used in local area networks (LAN) as well as wide area networks (WAN). LAN routers provide connectivity between multiple hardware assets, for example, in an office. It can establish connections with other networks on a WAN. A router allows your local network to interact with other networks on a WAN and also gives you features like traffic monitoring, etc.
There are many router types and network router brands like Cisco, HP, Juniper, D-Link, etc., available with us. Wireless routers use antennas to transmit data whereas wired routers share them through cables. Virtual routers are software that allows computers and servers to behave as routers. Edge routers share data packets between multiple networks but not within an individual network. Core routers share data packets within individual networks, but not between different networks.
