What is Router in Networking?
A Router is a networking device that sends, receives, and analyses data packets within the connected computer networks. A router is a layer three network device used in LAN (Local Area Network) and WAN (Wide Area Network) environments. When the data packet arrives, it inspects the destination IP address, consults its routing tables, calculates the best way to forward it and transfers it along the chosen route. Routers work on the routing protocol to prioritise the data to be transferred for each transmission. These are an essential part of modern computer networking, not just for establishing internet connections or data transmissions but also to provide additional security. By embedding firewalls and content filtering software, routers help businesses from malicious online websites and unwanted content. There are various routers available in the market depending upon their usages, such as wireless routers, edge routers, broadband routers, core routers and brouters.
