What is the role of a router in a network?

The role of a router in a network is to connect different networks. Routers are essential devices that manage traffic between multiple networks, directing data packets between them. They determine the best path for sending data to ensure that it reaches its destination as efficiently as possible. By connecting various devices on a local network, as well as linking these devices to the internet or other networks, routers facilitate communication and data transfer across diverse systems and network architectures.

Other choices highlight functions that do not pertain to the main responsibilities of a router. For instance, recharging devices is a function associated with power sources, while storing network history involves logging and monitoring tasks typically managed by dedicated servers or software, not routers. Amplifying signals is more aligned with devices like repeaters or switches that enhance signal strength, rather than the primary role of routing data traffic. Understanding the specific function of a router allows for clearer insights into how networks operate and interconnect.
