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 recall1 markAddressing Swap Remove

Devices are given IP addresses.

Define the term dynamic IP address.

[1 mark]
Mark scheme

Award one mark for:

  • (An IP address that) can change / is not permanent (1)

Allow a changing IP address.

Allow a temporary IP address.

Allow it is assigned each time the device connects to the internet.

Do not accept an IP address that is assigned (automatically) by a router/DHCP without any idea that it can change.

Do not accept static IP address / fixed IP address / an IP address that never changes (this is a static IP address).

Example answers and how they were marked
Full marks1/1

An IP address that can change each time the device connects to the internet.

Why: States that the IP address can change (1).

No marks0/1

An IP address that is assigned automatically by a router.

Why: Describes assignment only; the mark scheme does not accept assignment without the idea that the address can change.

No marks0/1

An IP address that never changes.

Why: Confuses dynamic with static; the Do not accept line applies.

3Describe2 marksWired Connections Swap Remove

A farm uses wired connections to link sensors in its fields to a computer in the farmhouse.

Describe how the range of a wired connection can affect the performance of this network.

[2 marks]
Mark scheme

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

  • (Twisted pair/copper) cable only carries data over a limited distance (about 100 metres) (1) so sensors further away need another switch/device to pass the data on to the farmhouse (1)
  • Fibre optic cable can carry data over much longer distances (1) so wired connections can reach sensors across the whole farm (1)
  • Data sent further than the cable's range is not received (1) so the computer in the farmhouse does not get readings from those sensors (1)
  • A wireless connection can reach sensors that are out of range of the cables (1) so a mix of the two can give readings across the whole site (1)

Allow responses about signal weakening/being lost over a long cable.

Do not accept responses about bandwidth or speed, as range is about distance, not the amount or rate of data.

Example answers and how they were marked
Full marks2/2

Twisted pair copper cable only carries data for about 100 metres so a switch is needed in each field to pass the readings on to the farmhouse.

Why: Point that copper cable has a limited distance (1) linked to needing another device to extend the network (1).

Some marks1/2

Fibre optic cable can carry data much further than copper cable.

Why: Gives the first point of a linked pair (1) but does not develop it to say what this allows the farm to do.

No marks0/2

A longer cable gives the network a bigger bandwidth so the sensors work faster.

Why: About bandwidth and speed rather than range, which the mark scheme says is not accepted.
