1Multiple choice1 markLANs & WANs Swap Remove

Networks can be classified by the area they cover.

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

[1 mark]
  • ALAN
  • BMAN
  • CPAN
  • DWAN
Mark scheme
  • D WAN (1)
  • The only correct answer is D. The correct answer is WAN (wide area network).
  • A is not correct because a LAN covers a small geographical area, such as one building
  • B is not correct because a MAN covers a city or large town
  • C is not correct because a PAN connects devices around one person, such as with Bluetooth
Example answers and how they were marked
Full marks1/1

D WAN

Why: Correct option: the internet is the largest example of a WAN (1).

No marks0/1

B MAN

Why: Near-miss: a MAN covers a city or large town, not networks all over the world, so the mark scheme gives it 0.

No marks0/1

A LAN

Why: Misconception: the candidate treats the internet as a LAN because their home network is a LAN; the mark scheme says a LAN covers a small geographical area, so 0.

2Convert2 marksBinary to Hexadecimal Conversion Swap Remove

Computer systems manipulate bit patterns.

Convert the binary pattern 1000 1010 to hexadecimal.

[2 marks]
Mark scheme

Award one mark for each correct digit in the correct position:

  • 8 (1)
  • A (1)

Answer: 8A

Example answers and how they were marked
Full marks2/2

8A

Why: Each nibble is one hexadecimal digit: 1000 = 8, 1010 = A: both digits are correct (2).

Some marks1/2

810

Why: One digit is correct (1), but a digit over 9 is written in denary instead of as a letter.

No marks0/2

A8

Why: The digits are the wrong way round, so neither is in the correct position.

3Short recall2 marksImages Swap Remove

Bitmap images are stored as a grid of pixels.

Define the term pixel.

[2 marks]
Mark scheme

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

  • The smallest element/area of a bitmap image (1)
  • The smallest identifiable part of an image (1)
  • Stores/represents a single colour as a binary value (1)
  • Stores/represents a single colour using a number of bits/colour depth (1)

Allow 'picture element' for element/part in the first two bullets, but not on its own

Allow 'bit depth' for colour depth

Do not accept 'picture element'/'pixel' on its own

Do not accept 'a group of pixels' or 'a dot' on its own; allow 'dot' only when it is described as the smallest element/area of the image

Do not accept 'single colour' on its own for the second mark; it must be linked to a binary value/number of bits

Do not accept 'lots of coloured dots' (it contradicts a single colour)

Example answers and how they were marked
Full marks2/2

The smallest identifiable area of a bitmap image, which has one colour stored as a binary value.

Why: Smallest identifiable area (1) and single colour stored as a binary value (1)

Some marks1/2

The smallest part of a bitmap image, made of one colour.

Why: Smallest part (1); no credit for the second mark because the single colour is not linked to a binary value or number of bits

No marks0/2

A picture element made from lots of coloured dots.

Why: 'Picture element' on its own is not accepted and 'lots of coloured dots' contradicts a single colour
