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.

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 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.
