1Multiple choice1 markSecondary Memory Swap Remove

A computer stores files on a hard disk drive.

A computer stores files on a hard disk drive.

Identify what the drive uses to read and write data.

[1 mark]
  • AA drive head that moves over the spinning platters
  • BA laser that measures reflected light
  • CA memory chip that traps electric charges
  • DA pit and land pattern burnt onto the surface
Mark scheme
  • A A drive head that moves over the spinning platters (1)
  • The only correct answer is A. The correct answer is a drive head.
  • B is not correct because a laser that measures reflected light is used by optical media such as a CD or Blu-ray Disc
  • C is not correct because trapping electric charges is how solid state (flash) storage stores data
  • D is not correct because pits and lands are burnt or pressed onto optical media, not onto a hard disk drive
Example answers and how they were marked
Full marks1/1

A A drive head that moves over the spinning platters

Why: Correct option (1): a hard disk drive uses a drive head that moves over the spinning platters to read and write data.

No marks0/1

D A pit and land pattern burnt onto the surface

Why: Near miss scoring 0: pits and lands are an optical feature, as line D of the mark scheme says. Only A is credited.

No marks0/1

C A memory chip that traps electric charges

Why: Misconception scoring 0: this confuses a hard disk drive with solid state storage, which stores data as trapped electric charges (line C).

2Multiple choice1 markEmbedded Systems Swap Remove

Identify the term for a computer that forms part of another device and performs a specific task.

[1 mark]
  • AEmbedded system
  • BGeneral purpose computer
  • CNetworked computer
  • DServer computer
Mark scheme
  • A Embedded system (1)
  • The only correct answer is A. The correct answer is embedded system.
  • B is not correct because a general purpose computer can run many different application programs
  • C is not correct because a networked computer is connected to other computers to share resources
  • D is not correct because a server computer provides services or resources to other computers on a network
Example answers and how they were marked
Full marks1/1

A Embedded system

Why: Correct option: an embedded system forms part of another device and performs a specific task (1).

No marks0/1

B General purpose computer

Why: Near miss: a general purpose computer can run many different application programs; it is not built into another device to perform a specific task, so no mark.

No marks0/1

D Server computer

Why: Misconception: a server provides services or resources to other computers on a network and is not an embedded system, so no mark.

3Explain2 marksPrimary Memory Swap Remove

A technician increases the amount of RAM in a laptop from 8 GiB to 16 GiB.

Explain one benefit of increasing the amount of RAM in a computer.

[2 marks]
Mark scheme

Award up to two marks for a linked explanation such as:

  • More applications/programs can be open/run at the same time (1) because more instructions and data can be held in main memory at once (1)
  • Programs run faster (1) because the CPU does not have to wait for instructions/data to be read/transferred from slower secondary storage (1)
  • The CPU waits/idles for less time (1) because instructions and data can be transferred to the CPU more quickly from RAM (1)

For both marks, the expansion must follow/associate with the statement.

Do not accept 'more files/photos/documents can be stored' or 'the computer has more storage' - this is a benefit of secondary storage, not RAM.

Do not accept 'the CPU becomes faster' or 'the clock speed increases'.

Example answers and how they were marked
Full marks2/2

More programs can be open at the same time because more instructions and data can be held in main memory at once.

Why: Linked point (1) for more programs running at the same time and reason (1) for more instructions and data being held in main memory at once.

Some marks1/2

Programs will run faster.

Why: Point (1) only; no linked reason such as the CPU not having to wait for data from slower secondary storage.

No marks0/2

There will be more space to save files and documents on the laptop.

Why: Misconception: the benefit given is a benefit of secondary storage, which the mark scheme's 'Do not accept' line rules out.
