Question

What device is designed specifically to reduce broadcast traffic that passes over a network and to choose the best path for moving those packets?

Answer 1

Answer:

Router        

Explanation:

• A router is a network device that forwards data packets between networks. Its a network layer hardware device. For example a DSL router that connects to the Internet through an internet service provider.
• Router is connects at least 2 networks (can be two LANs) and the ISP.
• Router is used to transfer data from one network to another if both networks use same protocols.
• It receives data in packets form and forwards the data to another router using a routing table. These data packets can be sent between devices or from devices to the internet.
• The routing table is used to choose the optimal path for forwarding the packets between the source and destination hosts. Routing table configure the best route a packet can take to reach its destination using routing protocols. A Routing Protocol defines how routers connect with each other and share information that makes them choose routes on a computer network between source and destination. Routing tables can be configured statically (routes are fed manually) or dynamically (routes are updated based on information obtained  from other routers).
• Router makes sure that the data packets reach right destination instead of being lost within the network and it also strengthen signals before transmitting them.
• Routers reduce broadcast traffic. They form boundaries between broadcast domains and separate a network into multiple broadcast domains.
• Router do not broadcast traffic and eliminates the packet when it detects a broadcast address. Routers also stop broadcast messages and don't route a broadcast message between broadcast domains.
