[1 mark]
  • AFTP
  • BIMAP
  • CPOP3
  • DSMTP
Mark scheme
  • C POP3 (1)
  • The only correct answer is C. The correct answer is POP3.
  • A is not correct because FTP is used to transfer files.
  • B is not correct because IMAP keeps emails on the server.
  • D is not correct because SMTP is used to send outgoing email between mail servers.
Example answers and how they were marked
Full marks1/1

C POP3

Why: POP3 downloads emails and removes them from the server (1).

No marks0/1

B IMAP

Why: IMAP keeps emails on the server, so it does not match the scenario where emails are removed from the server (0).

No marks0/1

D SMTP

Why: SMTP is used to send outgoing email, not to retrieve email (0).

2Short recall1 markLANs & WANs Swap Remove

A school's computers are connected in a local area network (LAN). The internet connects computers across the world.

State the type of network that the internet is an example of.

[1 mark]
Mark scheme

Award one mark for:

  • WAN/Wide Area Network (1)

Allow wide area network, WAN network, and minor spelling errors where the meaning is clear, e.g. 'wide area netowrk'.

Do not accept LAN/local area network.

Do not accept a description such as 'covers a large area' without naming WAN.

Do not accept 'the internet' or 'world wide web'.

Example answers and how they were marked
Full marks1/1

WAN (wide area network)

Why: Correct type of network (1).

No marks0/1

A network that covers a large area.

Why: Describes a WAN but does not name the type; no mark.

No marks0/1

LAN (local area network)

Why: Names the wrong type of network; the internet is a WAN.

3Explain2 marksThe Internet Swap Remove

A home network is connected to the internet by a router.

Explain one reason why a home network uses a router to connect its devices to the internet.

[2 marks]
Mark scheme

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

  • All the devices can share one internet connection (1) because the router forwards data packets between the home network and the internet (1)
  • Data can reach the correct device on the home network (1) because the router uses the destination IP address to forward each packet to that device (1)
  • Each device does not need its own separate connection to the internet (1) because the router forwards data packets for all the devices between the home network and the internet (1)

For both marks, the expansion must follow/associate with the statement.

Do not accept 'it provides Wi-Fi' because Wi-Fi is not why a router is needed to connect to the internet.

Do not accept 'it connects the home network/devices to the internet' or 'a router connects networks' without saying what the router does with the data, as this restates the question.

Do not accept 'it connects the cables' without saying what it does with the data.

Example answers and how they were marked
Full marks2/2

It lets all the devices share the internet connection because it forwards their data packets between the home network and the internet.

Why: Linked point (1) and reason (1): the router forwards data packets between the home network and the internet.

Some marks1/2

All the devices can share one internet connection because it connects the home network to the internet.

Why: Point (1) for sharing one internet connection, but the reason only restates that it connects the network to the internet, which the scheme does not accept.

No marks0/2

It provides Wi-Fi for the devices.

Why: Wi-Fi is not why a router is needed to connect to the internet; do not accept.
