1Multiple choice1 markLANs & WANs Swap Remove

A hospital has computers, printers and servers in one building.

Identify the type of network that connects these devices.

[1 mark]
  • ALAN
  • BPAN
  • CVPN
  • DWAN
Mark scheme
  • A LAN (1)
  • The only correct answer is A. The correct answer is LAN (Local Area Network).
  • B is not correct because a PAN connects devices around one person over a short range
  • C is not correct because a VPN is a secure private connection made over a public network, not a network covering one building
  • D is not correct because a WAN connects networks over a large geographical area
Example answers and how they were marked
Full marks1/1

A LAN

Why: Correct option: a LAN connects devices on one site, such as one building (1).

No marks0/1

D WAN

Why: Near miss: a WAN connects networks over a large geographical area, not devices within one building (0).

No marks0/1

C VPN

Why: Misconception: a VPN is a secure connection over a public network, not the type of network for devices in one building (0).

2Short recall1 markImages Swap Remove

A bitmap image has a resolution.

State what is meant by the resolution of an image.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • The concentration/density of pixels in an area (1)
  • The number of pixels per inch (PPI) / pixels per unit area (1)
  • The width and height/dimensions of the image in pixels (1)

Do not accept the number of pixels in the image on its own, without dimensions or an area, e.g. 'the total number of pixels'

Do not accept colour depth / the number of bits used per pixel / the number of colours

Do not accept file size in bytes / the amount of storage the image uses / screen size / image quality

Example answers and how they were marked
Full marks1/1

The concentration of pixels in an area, such as the number of pixels per inch.

Why: Gives the density/concentration of pixels in an area, and pixels per inch (1)

No marks0/1

The number of pixels in the image.

Why: A bare total pixel count is not accepted without dimensions or an area

No marks0/1

The number of bits used to store each pixel's colour.

Why: Describes colour depth, not resolution, and colour depth is not accepted

3Convert2 marksDenary to Hexadecimal Conversion Swap Remove

Computers manipulate binary patterns.

Convert the denary number 90 to hexadecimal.

[2 marks]
Mark scheme

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

  • 5 (1)
  • A (1)

Answer: 5A

Example answers and how they were marked
Full marks2/2

5A

Why: 90 ÷ 16 = 5 remainder 10, so the digits are 5 and A: both digits are correct (2).

Some marks1/2

510

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

No marks0/2

A5

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