L2 ICT U1 Packet Switching Quiz

What is packet switching?

• A method of data exchange over a network where data is broken down into packets.

• A type of network topology.

• A protocol for wireless communication.

• A cable used to connect different network devices.

What are the three main parts of a packet in packet switching?

• Header, footer, and body.

• Source address, destination address, and data.

• Header, payload, and trailer.

• Envelope, content, and checksum.

What does the header of a packet typically contain?

• The MAC address of the next hop.

• The IP address of where the data was sent from.

• The password for the network.

• The physical address of the device.

Why are packets sent independently over the network in packet switching?

• To follow a single route for all packets.

• To ensure data is encrypted.

• To use whatever route is fastest for each packet.

• To avoid using the internet.

What is the fundamental technology used in most local area networks and the internet?

• Ethernet

• Packet switching

• Bluetooth

• Dial-up connection

What is the purpose of the Destination Address in a data packet?

• To define the type of packet being transmitted

• To check that the packets have been reassembled correctly

• To identify the packet and help reassemble the data at the destination

• To know exactly where the data is being sent and ensure each packet reaches its intended location

What does the Payload section of a data packet contain?

• The IP address where the data is being sent

• The actual piece of the overall data that is being sent

• The unique identifier of the packet

• The error control bits to check packet reassembly

What is the benefit of packet switching in terms of delivery time?

• Data is split into larger packets for faster delivery

• Data is not split and sent as a whole for quicker delivery

• Data is split into smaller packets which can be transferred more quickly over a network

• Data packets are sent sequentially to ensure quick delivery

How does packet switching contribute to network efficiency?

• Each packet must arrive in order and take the same route

• Each packet can take the most efficient route and does not need to arrive in order

• All packets are delayed by network issues

• Packets are sent without regard to the efficiency of the route

What is the advantage of packet switching in terms of fault tolerance?

• Data packets are delayed by network issues and cannot be redirected

• Data packets are not delayed by network issues and can be easily redirected around these problems

• Data packets must be sent as a whole again if there is a network issue

• Network issues cause all packets to be lost and need resending
