How does a router enhance network performance?

• A. By encrypting user data
• B. By increasing the storage capacity
• C. By directing data traffic efficiently between networks
• D. By hosting websites

Answer: (C)

Routing data between networks improves performance. A router checks each packet’s destination address and uses routing tables to forward it along the best path toward its destination. By sending traffic only to the next hop and not broadcasting to every device, it reduces unnecessary network chatter and congestion, helping data reach its target more quickly. Dynamic routing can adapt to changing network conditions, keeping paths efficient. Features like NAT and QoS can further enhance performance by managing address use and prioritizing time-sensitive traffic. Encryption, extra storage, or hosting websites are separate functions and don’t inherently make routing more efficient.
