[1 mark]
  • ALAN
  • BPAN
  • CWAN
  • DWLAN
Mark scheme
  • C WAN (1)
  • The only correct answer is C. The correct answer is WAN, which connects networks over a large geographical area.
  • A is not correct because a LAN covers a limited area such as one building or site
  • B is not correct because a PAN connects devices around one person
  • D is not correct because a WLAN is a LAN that uses wireless connections and is still local
Example answers and how they were marked
Full marks1/1

C WAN

Why: Correct option: a WAN connects networks over a large geographical area (1).

No marks0/1

A LAN

Why: Distractor, not a partial-credit answer: each store may have its own LAN, but the network linking stores in different countries is a WAN (0).

No marks0/1

D WLAN

Why: A WLAN is still a local-area network that uses wireless connections and cannot connect stores in different countries (0).

2Short recall2 marksCharacter Sets Swap Remove

A computer uses a character set to represent text.

Define the term character set.

[2 marks]
Mark scheme

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

  • A set/collection of characters (1)
  • (Characters such as) letters, digits and symbols/punctuation (1)
  • Each character is represented by a unique code/binary value (1)
  • A standard set of characters so that text can be exchanged between computer systems (1)

Allow 'a list of characters that a computer can represent' for the first mark.

Do not accept a program/software that converts text into binary.

Do not accept 'a set of binary codes' on its own.

Example answers and how they were marked
Full marks2/2

A set of characters, such as letters, digits and punctuation, where each character is represented by a unique binary code.

Why: Set/collection of characters with examples (1) and each character has a unique code (1).

Some marks1/2

A set of letters and symbols that a computer can use to represent text.

Why: Awarded for the set/collection of characters (1); no creditworthy point saying each character has its own unique code (0).

No marks0/2

A program that converts the keys pressed on a keyboard into binary.

Why: Describes software that converts text, not a set of characters; the Do not accept line applies.
