1Multiple 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.

2Describe2 marksFile Management Swap Remove

File management is one function of an operating system.

Describe what the operating system does to the folder structure when a file is moved to a different folder.

[2 marks]
Mark scheme

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

  • Updates/changes the location/path stored for the file (1) so the file can be found in its new folder/location (1)
  • Removes the file's entry/reference from the old folder (1) so the file no longer appears/is listed there (1)
  • Adds/creates an entry/reference for the file in the new folder (1) so the file appears/is listed in its new location (1)
  • Updates the folder/directory listing/structure (1) to show the file's new location/path (1)

Do not accept descriptions of copying the file or leaving a duplicate in the old folder.

Do not accept deleting and recreating the file, or moving the file's data to a different physical location on the disk; the marks are for updating the folder/directory structure.

Example answers and how they were marked
Full marks2/2

It updates the location stored for the file so the file can be found in its new folder.

Why: Linked point (1) and development/outcome (1).

Some marks1/2

It removes the file's entry from the old folder.

Why: Creditworthy point (1) but no linked development.

No marks0/2

It deletes the file from the old folder and saves it again in the new folder.

Why: Describes deleting and recreating the file, which the mark scheme does not accept.

Mark scheme

Award one mark for each correct nibble in the correct order:

  • 1110 (1)
  • 0100 (1)

0 marks if the response is not 8-bit binary.

Example answers and how they were marked
Full marks2/2

1110 0100

Why: 149 + 79 = 228, carrying where a column adds to 2: both nibbles are correct (2).

Some marks1/2

1110 0101

Why: A slip in the last bit. The first nibble is correct (1); the second is not.

No marks0/2

1101 1111

Why: Writes 1 in every column with a 1 and never carries. Neither nibble is correct.
