Year 10 Networks

Which of the following is a key difference between a WAN and a LAN?

• WANs connect devices within a single building, while LANs connect across cities.

• LANs typically cover smaller geographical areas than WANs.

• WANs do not require hardware to operate, while LANs do.

• LANs use the Internet as their backbone, while WANs use private connections.

LANs use the Internet as their backbone, while WANs use private connections.

Which of the following best describes how packets are used to send data across the Internet?

• Data is broken into packets, each carrying its destination address and reassembled upon arrival.

• Packets always travel together through the same route.

• Each packet contains only the sender’s address and relies on routers to determine its destination.

• Packets cannot be lost or arrive out of order.

What is a key benefit of using layers in the TCP/IP model?

• Allows secure communication between devices.

• Reduces complexity by splitting responsibilities into manageable parts.

• Ensures that every packet is sent twice for verification.

• Makes the system hardware-dependent.
