1Multiple choice1 markPacket Switching Swap Remove

Data is broken into packets and sent across the internet.

Identify the device that forwards a packet towards its destination.

[1 mark]
  • AHub
  • BRouter
  • CServer
  • DSwitch
Mark scheme
  • B Router (1)
  • The only correct answer is B. The correct answer is Router.
  • A is not correct because a hub sends the data it receives to every device on the network
  • C is not correct because a server provides services, such as web pages, to client computers
  • D is not correct because a switch forwards data between the devices on one network
Example answers and how they were marked
Full marks1/1

B Router

Why: Selected the correct device: a router reads the destination IP address in each packet and forwards it towards its destination (1).

No marks0/1

D Switch

Why: A near miss: a switch forwards data between devices on one network, but it is a router that forwards packets between networks towards their destination, so no mark.

No marks0/1

A Hub

Why: Misconception from the examiners' reports: confusing LAN hardware with internet routing. A hub sends data to every device on the network and does not read IP addresses to forward packets, so no mark.

2Multiple choice1 markAddressing Swap Remove

A packet of data is sent across the internet to a web server. The packet has a header that stores information about the packet.

Identify the information in the packet header that a router uses to forward the packet towards its destination.

[1 mark]
  • AThe destination domain name
  • BThe destination IP address
  • CThe MAC address of the sender
  • DThe name of the file being sent
Mark scheme
  • B The destination IP address (1)
  • The only correct answer is B. The correct answer is the destination IP address.
  • A is not correct because a domain name is converted to an IP address by a DNS server before routing begins
  • C is not correct because the sender's MAC address is only used to deliver the packet on the local network
  • D is not correct because the file name is not used to route packets
Example answers and how they were marked
Full marks1/1

B The destination IP address

Why: Correct option (1): a router reads the destination IP address in the header to forward the packet towards its destination.

No marks0/1

A The destination domain name

Why: A domain name is converted to an IP address by a DNS server before routing begins, so it is not the routing information in the header (mark scheme line A); no mark.

No marks0/1

C The MAC address of the sender

Why: The sender's MAC address is only used to deliver the packet on the local network, so it is not used by the router to forward the packet (mark scheme line C); no mark.

3Short recall2 marksWired Connections Swap Remove

A company can choose between two wired connections. Connection B has a higher bandwidth than connection A.

Give two benefits to the company of choosing connection B.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • Files/data download/upload more quickly (1)
  • More employees can use the connection at the same time without it slowing down (1)
  • Web pages/streamed video load more quickly with less buffering (1)
  • Video calls/conferencing run at a higher quality (1)
  • Updates/backups can be completed in less time (1)

Allow 'multiple users' or 'more devices' for the shared-use point

Allow 'video streams more quickly' or 'less buffering' on their own

Do not accept lower latency, as a higher bandwidth does not reduce latency

Do not accept 'more data can be transferred per second' or 'a bigger bandwidth', as these repeat what bandwidth is

Do not accept 'more reliable' on its own, as a higher bandwidth does not make a wired connection more reliable

Example answers and how they were marked
Full marks2/2

Files will download more quickly, and more employees can use the internet at the same time without the connection slowing down.

Why: Files download more quickly (1) and more users without slowdown (1).

Some marks1/2

Web pages will load faster and the connection will have a longer range.

Why: Web pages load faster (1); the range of a connection is not increased by bandwidth, so that point is not credited.

No marks0/2

The connection will be more reliable because it has a bigger bandwidth.

Why: 'More reliable' is not credited on its own and 'bigger bandwidth' repeats the question, so no marks.

4Short recall1 markWired Connections Swap Remove

Wired connections have characteristics that affect network performance.

State what is meant by the range of a wired network connection.

[1 mark]
Mark scheme

Award one mark for:

  • The maximum distance data/a signal can be transmitted before it becomes too weak to be received (1)

Allow 'how far a signal can travel'.

Do not accept the number of devices that can be connected to the network.

Do not accept the speed at which data is transmitted.

Do not accept bandwidth/the maximum capacity of a channel.

Do not accept latency/the delay between a signal being sent and received.

Example answers and how they were marked
Full marks1/1

The maximum distance a signal can be transmitted before it becomes too weak to be received.

Why: Gives the maximum distance a signal can be transmitted before it becomes too weak, which is the creditworthy point (1).

No marks0/1

The maximum capacity of the connection.

Why: This describes bandwidth, which the mark scheme says not to accept for range, so no mark.

No marks0/1

The delay between a signal being sent and received.

Why: This describes latency/delay, which the mark scheme says not to accept for range, so no mark.
