Routers lead the line as the first line of network security in homes and offices. It prevents intrusion into a network while creating a firewall to provide the highest level of security on several network types. They are the best ways of keeping computer systems, network systems, and information contained in them safe from intrusion.

A router is designed to be more capable than several other network devices such as hubs or switches that can only carry out basic network functions. For instance, a hub only transfers data between network devices without analyzing or doing anything with those data. On the other hand, routers are able to analyze data sent between network devices. They can change the packaging of such data and send it over to a different network.

Routers are the perfect devices to share an internet connection between multiple computers in home networks. A router typically connects to the modem using a network cable. Router networking occurs via a WAN port or the internet. There are also wireless routers that connect to devices using different wireless standards.
