Title: What is the role of a router in a network?

In a computer network, a router plays a crucial role in directing data packets between different networks. It acts as a gateway, connecting multiple devices and ensuring efficient data transmission. Routers use IP addresses to determine the best path for data to travel, allowing for seamless communication between devices. Additionally, routers provide security by implementing firewalls and other security measures to protect the network from external threats. Overall, routers are essential hardware components that enable the smooth functioning of modern computer networks.
