What role does a router play in sending data across the Internet?

• A. Forwards packets between networks using routing tables to reach the destination.
• B. Stores cookies on your device.
• C. Encrypts data end-to-end.
• D. Provides the physical power supply for network devices.

Answer: (A)

A router’s job is to connect different networks and forward data from one network to another. It examines a packet’s destination IP address and consults its routing table, which acts like a map of the best next hop for reaching that destination. By choosing the appropriate next router or network segment and sending the packet onward, routers move data across many networks until it reaches the destination’s local network and finally the device itself. Cookies stored on your device are handled by browsers and websites, not by routers. End-to-end encryption is typically provided by protocols like TLS or VPNs, not the router’s basic function. Providing physical power is about hardware power supply, not routing data.
