What is the primary function of a router in a network?

• A. Forwards a request from one computer to another
• B. Stores files on the network
• C. Routes internet traffic by pointing data to its destination
• D. Provides power to network devices

Answer: (A)

Routing is about directing data packets between different networks, using destination IP addresses to decide the next hop. A router sits at the boundary between networks (for example, your home network and the internet) and determines the best path for each packet, so that information can travel across networks to its destination. This is why the router’s primary job is to route internet traffic by pointing data toward where it’s supposed to go, rather than just delivering a message to another computer within the same local network or providing storage or power. The other ideas describe roles for storage devices (storing files) or power provision to devices, which aren’t what routers do.
