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 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.

3Describe2 marksAddressing Swap Remove

Devices on a network use IP addresses.

Describe the purpose of an IP address.

[2 marks]
Mark scheme

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

  • Identifies a device on a network (1) so data can be sent to the correct device (1)
  • Gives a device a unique address (1) so packets can be routed to it across the internet (1)
  • Identifies a device on the internet (1) so it can send/receive data to/from other devices (1)

Allow 'unique' only where it is linked to identifying the device or to routing data; 'unique' on its own is not creditworthy.

Do not accept answers that only say it connects a device to the internet.

Do not accept a MAC address as the purpose of an IP address.

Do not accept domain names/web addresses (e.g. google.co.uk) as an IP address.

Example answers and how they were marked
Full marks2/2

An IP address uniquely identifies a device on a network so that data packets can be delivered to the correct destination.

Why: Linked point (1): identifies a device on a network; development (1): so data can be sent to the correct device.

Some marks1/2

It identifies a device on a network.

Why: Point only (1): identifies a device on a network; no linked development.

No marks0/2

It is a website address, such as google.co.uk, that the browser uses to find a web page.

Why: No creditworthy point: gives a domain name/web address, which the mark scheme says not to accept as an IP address.
