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).

2Short recall2 marksWired Connections Swap Remove

A school connects its desktop computers to the network using cables.

Give two reasons why the wired connections give better network performance than the wireless connections.

[2 marks]
Mark scheme

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

  • Faster transmission speed (1)
  • Higher bandwidth (1)
  • Lower latency (1)
  • Not affected by interference (from other devices/walls) (1)
  • No blind spots/not affected by distance from the wireless access point (1)

Do not accept benefits of wireless connections, e.g. users can move around the building with their devices

Do not accept 'easier to set up' or 'does not need a password' as these are not about network performance

Example answers and how they were marked
Full marks2/2

The wired connection is not affected by interference from other devices, and it has a lower latency than Wi-Fi.

Why: Interference point (1) and lower latency point (1).

Some marks1/2

It has a faster transmission speed and the users can move around the building with their computers.

Why: Faster transmission speed (1); moving around is a benefit of wireless, so is not credited.

No marks0/2

It is easier to set up the network and the users do not need a password.

Why: Neither point is about network performance; the mark scheme does not accept 'easier to set up' or password points, so no marks.

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.
