1Multiple choice1 markProtocols & Layers Swap Remove

A user reads email on a laptop. The emails are downloaded to the laptop and removed from the mail server.

Identify the email protocol being used.

[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).

2Multiple choice1 markAddressing Swap Remove

Data is sent across the internet in packets.

Identify the device that uses IP addresses to forward packets from one network to another.

[1 mark]
  • AHub
  • BNetwork interface card
  • CRouter
  • DSwitch
Mark scheme
  • C Router (1)
  • The only correct answer is C. The correct answer is router.
  • A is not correct because a hub sends data to every device on the network
  • B is not correct because a network interface card connects a device to a network
  • D is not correct because a switch forwards data within a single network using MAC addresses
Example answers and how they were marked
Full marks1/1

C Router

Why: Correct option (1): a router uses IP addresses to forward packets between networks.

No marks0/1

D Switch

Why: A switch forwards data within one network using MAC addresses, not between networks (mark scheme line D), so no mark.

No marks0/1

A Hub

Why: A hub only sends data to every device on the network (mark scheme line A), so no mark.

3Short recall2 marksWireless Connections Swap Remove

Wireless connections use radio waves.

Give two reasons why a wireless connection can have a lower speed than a wired connection.

[2 marks]
Mark scheme

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

  • Interference from other electrical/electronic devices (1)
  • Walls/obstacles block or weaken the signal (1)
  • The signal gets weaker the further a device is from the access point (1)
  • Other devices/networks use the same wireless channel/frequency (1)
  • A wireless channel has less bandwidth than a wired connection (1)

Do not accept 'higher latency', because latency is a delay and does not reduce the speed at which data is transferred.

Do not accept 'wireless is slower' / 'wired is faster' without a reason.

Do not accept 'radio waves are slower than signals in a cable' as they travel at the same speed.

Example answers and how they were marked
Full marks2/2

Other electrical devices can cause interference, and walls can block the signal.

Why: Gives interference (1) and walls blocking the signal (1).

Some marks1/2

Walls can block the wireless signal.

Why: Gives one valid reason, walls blocking the signal (1), but no second reason.

No marks0/2

Wireless is slower because it has a higher latency, so the data takes longer to arrive.

Why: Confuses latency (a delay) with speed; 'higher latency' is not accepted and no other creditworthy reason is given.
