[1 mark]
  • AFTP
  • BHTTP
  • CSMTP
  • DTCP
Mark scheme
  • C SMTP (1)
  • The only correct answer is C. The correct answer is SMTP.
  • A is not correct because FTP is used to upload and download files
  • B is not correct because HTTP is used to request web pages
  • D is not correct because TCP is a transport-layer protocol that splits data into packets and reassembles them
Example answers and how they were marked
Full marks1/1

C SMTP

Why: Selected the correct email sending protocol (1).

No marks0/1

A FTP

Why: FTP is a file transfer protocol, not an email sending protocol, so no mark is awarded (0).

No marks0/1

B HTTP

Why: HTTP is used for requesting web pages, not for sending email, so no mark is awarded (0).

2Multiple choice1 markWireless Connections Swap Remove

A wireless network can use the 2.4 GHz or 5 GHz frequency band.

Identify the advantage of using the 5 GHz band instead of the 2.4 GHz band.

[1 mark]
  • AGreater range
  • BHigher data transfer speed
  • CMore able to pass through walls
  • DUses less bandwidth
Mark scheme
  • B Higher data transfer speed (1)
  • The only correct answer is B. The correct answer is higher data transfer speed.
  • A is not correct because the 2.4 GHz band has the greater range
  • C is not correct because the 2.4 GHz band passes through walls more easily
  • D is not correct because the 5 GHz band does not use less bandwidth
Example answers and how they were marked
Full marks1/1

B Higher data transfer speed

Why: Correct advantage: 5 GHz gives higher data transfer rates (1).

No marks0/1

A Greater range

Why: Greater range is a feature of the 2.4 GHz band, not an advantage of 5 GHz; no mark.

No marks0/1

C More able to pass through walls

Why: 5 GHz signals are less able to pass through walls than 2.4 GHz signals; no mark.

3Short recall2 marksLANs & WANs Swap Remove

A school has computers in every classroom.

Define the term 'local area network (LAN)'.

[2 marks]
Mark scheme

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

  • A network that covers a small geographical area / is on a single site / is within one building (1)
  • (Two or more) computers/devices connected together (1)
  • So that the connected devices can share data/files/resources such as printers or an internet connection (1)
  • Uses cabling/infrastructure owned by the organisation (1)

Do not accept a network that covers a large geographical area / connects networks in different countries, as this describes a WAN.

Do not accept 'a network in a school' on its own, as this repeats the stem without a LAN feature such as a single site or connected devices.

Do not accept 'a network that connects to the internet' without a LAN feature such as a single site or connected devices.

Do not accept 'owned by one organisation' on its own, as a WAN can also be owned by one organisation.

Do not accept 'local' on its own without saying what it means.

The share mark needs the sharing to be linked to the connected devices/network, e.g. 'share files' or 'share printers'.

Example answers and how they were marked
Full marks2/2

A LAN is a group of computers connected together on one site, such as a school, so that they can share files and printers.

Why: Connected together (1) and single site (1); the sharing point is also made but the maximum is two marks.

Some marks1/2

A network that is in one building.

Why: Covers a single site/one building (1) but does not say that devices are connected together or what they share.

No marks0/2

A network that covers a large area and connects different countries.

Why: Describes a WAN, not a LAN, so no creditworthy LAN point is made.
