Which information is used by routers to forward a data packet toward its destination? 2. A computer has to send a packet to a destination host in the same LAN. How will the packet be sent?
Understand the Problem
The questions are asking about the functioning of routers in networking, specifically regarding how packets are forwarded based on IP and how packets are sent within a Local Area Network (LAN). The first question addresses which information is crucial for routers to determine the correct path for a packet, while the second question focuses on the method a computer uses to send packets to another computer in the same LAN.
Answer
Destination IP address; direct send using MAC address on LAN.
Routers use the destination IP address to forward a packet towards its destination. On a LAN, a packet is sent directly to the destination host using its MAC address.
Answer for screen readers
Routers use the destination IP address to forward a packet towards its destination. On a LAN, a packet is sent directly to the destination host using its MAC address.
More Information
In a network, routers rely on the destination IP address to make decisions on packet forwarding. On a Local Area Network (LAN), communication happens at the data link layer using MAC addresses, which allows direct device-to-device communication without needing a router.
Tips
Confusing IP and MAC addresses can lead to mistakes. IP addresses are used by routers for routing decisions, while MAC addresses are used within local network segments.
