1Describe2 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.

2Describe2 marksProcess Management Swap Remove

An operating system manages the processes running on a computer.

Describe the purpose of process management.

[2 marks]
Mark scheme

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

  • Decides which process is given use of the CPU (1) so that more than one program can run/appear to run at the same time (1)
  • Allocates CPU time to each process (1) so that no single process takes control of the CPU (1)
  • Manages the states/life-cycle of each process (1) so processes can be moved between ready/running/blocked (1)
  • Keeps track of the processes and their status (1) so a process waiting for a resource can be returned to the CPU when it is ready (1)

Do not accept responses that only describe what a process is.

Do not accept responses that only list the types of operating system management.

Example answers and how they were marked
Full marks2/2

It decides which process will use the CPU so that several programs can run without one taking over the processor.

Why: Decision about CPU use (1) linked to allowing several programs to run (1).

Some marks1/2

It decides which process uses the CPU.

Why: One creditworthy point about choosing a process for the CPU (1), but no linked development.

No marks0/2

It makes sure the computer has enough RAM to store files.

Why: Describes memory/file management, not process management; no creditworthy point.

3Describe2 marksUtility Software Swap Remove

A hard disk can become fragmented as files are saved and deleted.

Describe how disk defragmentation software improves the performance of a hard disk.

[2 marks]
Mark scheme

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

  • Parts of a file are moved so they are stored together/in consecutive locations (1) so the read/write head has less distance to travel to read the file (1)
  • Files are rearranged so that each file is stored in one block (1) which reduces the time taken to open/load the file (1)
  • Free space on the disk is collected into one area (1) so new files can be saved without becoming fragmented (1)
  • The parts of each fragmented file are put in order (1) so fewer movements of the read/write head are needed to read it (1)

Do not accept responses about compressing files, deleting files or increasing the amount of storage, as these are not what defragmentation software does.

Do not accept 'it makes the disk faster' without saying how the files are changed.

Example answers and how they were marked
Full marks2/2

It moves the parts of a file so they are stored together in consecutive locations, so the read/write head does not have to move as far and the file opens more quickly.

Why: Linked point (1) and development (1): the file parts are stored together, which reduces read/write head movement.

Some marks1/2

It reorganises the files on the hard disk so that they are stored together.

Why: The point is made (1) but there is no development saying how this improves performance, so the second mark is not awarded.

No marks0/2

It compresses the files so that they take up less space on the disk.

Why: This describes data compression software, which the mark scheme says is not accepted; no creditworthy point is made.
