What role does a router play in networking?

• A. It connects a computer to the internet
• B. It directs data packets between networks
• C. It filters internet traffic
• D. It stores data packets

Answer: (B)

A router serves as a critical component in networking by directing data packets between different networks. When devices on one network need to communicate with devices on another network, the router analyzes the data packets and determines the best path for them to travel. This process is essential for enabling communication across various segments of the internet. Routers utilize various protocols and algorithms to read the destination addresses of the data packets, making intelligent decisions to ensure efficient routing. They can forward data to the correct destination through multiple pathways and may also manage traffic to prevent congestion, enhancing network performance. The other roles mentioned in the choices, while related to networking, do not accurately describe the primary function of a router. Connecting a computer to the internet is often the role of a modem or access point, filtering internet traffic can be a function of firewalls or more advanced routers but is not the definitive role of a router, and routers do not store data packets; they simply pass them along to their destination. This distinction emphasizes why directing data packets between networks is the most accurate and fundamental description of a router's role.
