A router is a networking device that is basically used for providing safe routes for data packets. Cisco is a firm that provides the best Cisco routers. Data packets are nothing but our data like email, files and etc. These data are wrapped into packets and sent over the internet to the intended receiver. A router acts as a Junction for redirecting or directing routes for the data packets. These data packets contain sender and receiver information in encrypted form. Information is stored inside a table. These packets travel through various routers in between sender and receiver. It takes a halt, which is known as hop at different network routers to get the target router destination. The number of hops is determined by the sender router itself. If the selected number of hops halt is exceeded, then the data packets are sent back to the sender router.
