1Multiple choice1 markPrimary Memory Swap Remove

Identify what is fetched from RAM during the fetch stage.

[1 mark]
  • AThe next instruction
  • BThe data at a memory address
  • CThe decoded instruction
  • DThe address of the next instruction
Mark scheme
  • A The next instruction (1)
  • The only correct answer is A. The correct answer is the next instruction.
  • B is not correct because data is fetched during the execute stage
  • C is not correct because an instruction is decoded after it is fetched
  • D is not correct because the program counter holds the address used to fetch the instruction
Example answers and how they were marked
Full marks1/1

A The next instruction

Why: The next instruction is fetched from RAM during the fetch stage (1).

No marks0/1

B The data at a memory address

Why: Near miss: data is not fetched during the fetch stage; data is used during the execute stage.

No marks0/1

C The decoded instruction

Why: Misconception: an instruction is decoded after it is fetched, in the decode stage.

2Multiple choice1 markEmbedded Systems Swap Remove

Modern cars contain many embedded systems.

Identify what the embedded system that controls the cruise control does.

[1 mark]
  • AIt controls the interior lights
  • BIt displays a map for the driver
  • CIt keeps the car at a constant speed
  • DIt sounds an alarm if the car is broken into
Mark scheme
  • C It keeps the car at a constant speed (1)
  • The only correct answer is C. The correct answer is it keeps the car at a constant speed.
  • A is not correct because controlling the interior lights is done by a different embedded system in the car
  • B is not correct because displaying a map for the driver is done by the satellite navigation system
  • D is not correct because sounding an alarm is done by a different embedded system in the car
Example answers and how they were marked
Full marks1/1

C It keeps the car at a constant speed

Why: Correct option: this is the function of the embedded system that controls the cruise control (1).

No marks0/1

B It displays a map for the driver

Why: Near miss: displaying a map is the function of the satellite navigation system, which the mark scheme says is not correct, so no mark.

No marks0/1

A It controls the interior lights

Why: Misconception: the interior lights are controlled by a different embedded system, 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.
