1Multiple choice1 markThe Internet Swap Remove

Identify the term for the number that identifies a device on a network.

[1 mark]
  • ADomain name
  • BIP address
  • CPacket
  • DSequence number
Mark scheme
  • B IP address (1)
  • The only correct answer is B. The correct answer is IP address.
  • A is not correct because a domain name is a name that identifies a website, not the address of a device
  • C is not correct because a packet is a small block of data with header information sent across a network
  • D is not correct because a sequence number is used to put packets back into the correct order
Example answers and how they were marked
Full marks1/1

B IP address

Why: Correct option: the IP address is the number that identifies a device on a network (1).

No marks0/1

A Domain name

Why: Near miss: a domain name is a name that identifies a website, not the address of a device, so A is not credited.

No marks0/1

D Sequence number

Why: Shows the misconception that any number carried in a packet header, here the one used to reorder packets, is the address of the device; D is not credited.

2Short recall2 marksWired Connections Swap Remove

A school connects its desktop computers to the network using cables.

Give two reasons why the wired connections give better network performance than the wireless connections.

[2 marks]
Mark scheme

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

  • Faster transmission speed (1)
  • Higher bandwidth (1)
  • Lower latency (1)
  • Not affected by interference (from other devices/walls) (1)
  • No blind spots/not affected by distance from the wireless access point (1)

Do not accept benefits of wireless connections, e.g. users can move around the building with their devices

Do not accept 'easier to set up' or 'does not need a password' as these are not about network performance

Example answers and how they were marked
Full marks2/2

The wired connection is not affected by interference from other devices, and it has a lower latency than Wi-Fi.

Why: Interference point (1) and lower latency point (1).

Some marks1/2

It has a faster transmission speed and the users can move around the building with their computers.

Why: Faster transmission speed (1); moving around is a benefit of wireless, so is not credited.

No marks0/2

It is easier to set up the network and the users do not need a password.

Why: Neither point is about network performance; the mark scheme does not accept 'easier to set up' or password points, so no marks.

3Describe2 marksWireless Connections Swap Remove

A school provides a wireless network for its students.

Describe how the range of a wireless network can affect its performance.

[2 marks]
Mark scheme

Award up to two marks for a linked description such as:

  • The further a device is from the wireless access point (1) the weaker the signal becomes (1)
  • A device outside the range of an access point (1) cannot connect to the network / loses its connection (1)
  • Walls and other obstacles reduce the range of the signal (1) so some areas of a building have a poor or no connection (1)
  • A wireless network with a greater range (1) allows devices to connect from further away (1)

Do not accept responses that only state that range is measured in metres or give a definition of range, as these do not describe an effect on performance.

Do not accept responses about the number of devices or interference unless they are linked to range.

Example answers and how they were marked
Full marks2/2

The further a device is from the access point, the weaker the signal becomes, so the device may lose its connection.

Why: Linked point: distance from the access point (1), developed by the weaker signal and lost connection (1).

Some marks1/2

Walls and other objects can reduce the range of a wireless signal.

Why: Point given: obstacles reduce range (1), but there is no development of the effect on performance.

No marks0/2

Range is the maximum distance a wireless signal can travel.

Why: A definition of range, not a description of its effect on performance, which the mark scheme does not accept.
