1Multiple choice1 markSecondary Memory Swap Remove

A computer has both primary and secondary storage.

Identify the role of secondary storage.

[1 mark]
  • ATo store data and programs permanently
  • BTo store data and instructions currently in use
  • CTo carry out calculations on data
  • DTo allow the CPU to access programs directly
Mark scheme
  • A To store data and programs permanently (1)
  • The only correct answer is A. The correct answer is to store data and programs permanently.
  • B is not correct because storing the data and instructions currently in use is the role of primary storage/RAM, which is volatile, not the role of secondary storage
  • C is not correct because calculations on data are carried out by the CPU, not by secondary storage
  • D is not correct because secondary storage is not directly accessible by the CPU; data must first be copied into RAM
Example answers and how they were marked
Full marks1/1

A To store data and programs permanently

Why: Correct option (1): storing data and programs permanently is the role of secondary storage, which is non-volatile.

No marks0/1

B To store data and instructions currently in use

Why: Near miss scoring 0: this describes primary storage/RAM, which is volatile, and is not the role of secondary storage (line B of the mark scheme). Only A is credited.

No marks0/1

D To allow the CPU to access programs directly

Why: Misconception scoring 0: candidates think the CPU reads programs straight from secondary storage, but secondary storage is not directly accessible by the CPU (line D).

2Multiple choice1 markEmbedded Systems Swap Remove

Identify the device that is a general purpose computer.

[1 mark]
  • ADesktop computer
  • BMicrowave oven
  • CWashing machine
  • DTraffic light
Mark scheme
  • A Desktop computer (1)
  • The only correct answer is A. The correct answer is Desktop computer.
  • B is not correct because a microwave oven uses an embedded system, built into it, to control a dedicated function
  • C is not correct because a washing machine uses an embedded system, built into it, to control a dedicated function
  • D is not correct because a traffic light uses an embedded system, built into it, to control a dedicated function
Example answers and how they were marked
Full marks1/1

A Desktop computer

Why: Correct option: the question asks for the general purpose computer, and a desktop computer is general purpose; it does not use an embedded system to control a dedicated function (1).

No marks0/1

B Microwave oven

Why: Near miss: a microwave oven is the kind of device that uses an embedded system, built into it, to control a dedicated function, so it is not a general purpose computer; mark scheme says B is not correct.

No marks0/1

C Washing machine

Why: Misconception: because a washing machine contains a computer, it must be a general purpose computer; it actually uses an embedded system built into it for a dedicated function, so no mark.

3Short recall1 markPrimary Memory Swap Remove

Computers use RAM to store the data and instructions that are in use.

Name the term used to describe memory that loses its contents when the power is switched off.

[1 mark]
Mark scheme

Award one mark for:

  • Volatile (1)

Allow volatile memory / it is volatile.

Do not accept non-volatile, ROM, RAM or temporary/short term memory on their own, as these are not the term asked for.

Example answers and how they were marked
Full marks1/1

Volatile

Why: Correct term for memory that loses its contents when the power is switched off (1).

No marks0/1

Temporary memory

Why: Describes what such memory does but is not the term asked for; 'temporary memory' is on the Do not accept line, so no mark.

No marks0/1

Non-volatile

Why: Non-volatile memory keeps its contents when the power is switched off, the opposite of what the question describes; it is explicitly not accepted.
