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 markWireless Connections Swap Remove

A wireless network can use the 2.4 GHz or 5 GHz frequency band.

Identify the advantage of using the 5 GHz band instead of the 2.4 GHz band.

[1 mark]
  • AGreater range
  • BHigher data transfer speed
  • CMore able to pass through walls
  • DUses less bandwidth
Mark scheme
  • B Higher data transfer speed (1)
  • The only correct answer is B. The correct answer is higher data transfer speed.
  • A is not correct because the 2.4 GHz band has the greater range
  • C is not correct because the 2.4 GHz band passes through walls more easily
  • D is not correct because the 5 GHz band does not use less bandwidth
Example answers and how they were marked
Full marks1/1

B Higher data transfer speed

Why: Correct advantage: 5 GHz gives higher data transfer rates (1).

No marks0/1

A Greater range

Why: Greater range is a feature of the 2.4 GHz band, not an advantage of 5 GHz; no mark.

No marks0/1

C More able to pass through walls

Why: 5 GHz signals are less able to pass through walls than 2.4 GHz signals; no mark.

3Short recall2 marksLANs & WANs Swap Remove

A bank connects its offices in several countries together.

Define the term 'wide area network (WAN)'.

[2 marks]
Mark scheme

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

  • A network that covers a large geographical area / connects locations in different cities/countries (1)
  • Two or more LANs/local area networks connected together (1)
  • Uses infrastructure owned by a third party / rented from a telecoms provider (1)
  • Uses leased lines (1)

Allow 'two or more networks connected together' only if the answer says they are in different/remote locations.

Do not accept a network that covers a small area / is on one site, as this describes a LAN.

Do not accept 'wide' on its own without saying what it means.

Do not accept that devices can share data/resources over a long distance on its own, as this is a purpose of a WAN and not a defining feature.

Example answers and how they were marked
Full marks2/2

A WAN connects two or more LANs together over a large geographical area, for example in different countries.

Why: Large geographical area (1) and two or more LANs connected together (1).

Some marks1/2

A network that covers a large area.

Why: Large geographical area (1) but does not say it connects LANs or uses third-party/leased infrastructure.

No marks0/2

A network in one building that lets computers share a printer.

Why: Describes a LAN on one site, which the mark scheme says not to accept, so no creditworthy point is given.
