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 markCompression Swap Remove

A company backs up its files to an external hard drive.

Give one reason why the company compresses the files before backing them up.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • More files/data can be stored (in the same storage space) (1)
  • The files take up less storage space (1)
  • The backup is quicker/faster to complete (1)
  • Less data needs to be transferred to the backup device (1)

Do not accept 'makes the files more secure' or 'encrypts the files'.

Example answers and how they were marked
Full marks1/1

The compressed files take up less storage space, so more files can be backed up.

Why: The files take up less storage space (1).

No marks0/1

It reduces the amount of disk fragmentation.

Why: Near-miss: compression does not reduce disk fragmentation.

No marks0/1

It encrypts the files so they are safer if the drive is stolen.

Why: Misconception: compression does not encrypt files, and security 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.
