1Short recall2 marksFile Management Swap Remove

An operating system provides file management.

Define the term file management.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • The part/function of the operating system (1)
  • That manages/organises files (and folders) (1)
  • On a storage device/disk (1)
  • So files can be stored/found/retrieved (1)

Do not accept managing processes/peripherals/users as the whole definition.

Example answers and how they were marked
Full marks2/2

The function of the operating system that organises files and folders on a disk so they can be found and retrieved.

Why: Names the operating system function (1) and managing/organising files on a disk so they can be retrieved (1).

Some marks1/2

Organising files.

Why: Names managing/organising files (1), but does not name the operating system, storage location or retrieval.

No marks0/2

Managing the CPU and peripherals.

Why: Describes process and peripheral management, not file management.

2Short recall2 marksPurpose & Function of Operating Systems Swap Remove

A computer can run more than one process at a time.

Give two tasks carried out by the process management function of an operating system.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • Deciding which process runs next on the CPU/scheduling processes (1)
  • Allocating processor/CPU time to processes/allowing multitasking (1)
  • Managing the process life-cycle/process states (ready, running, blocked) (1)
  • Handling interrupts so a running process is suspended and another can run (1)
  • Stopping/terminating a process when it has finished (1)

Do not accept 'managing processes' on its own.

Do not accept 'handling interrupts' on its own.

Do not award two marks for the same task expressed twice, e.g. 'deciding which process runs next' and 'scheduling processes', or 'allocating CPU time' and 'giving each process a share of processor time'.

Do not accept 'managing memory/memory management', 'managing files/file management' or 'managing devices/peripherals' (these are other functions of an operating system).

Example answers and how they were marked
Full marks2/2

Deciding which process runs next on the CPU and stopping a process when it has finished.

Why: Scheduling a process (1) and terminating a process (1) are two different named tasks.

Some marks1/2

Deciding which process runs next and scheduling processes.

Why: Both points are the same task expressed twice, so only one mark is awarded under the guidance.

No marks0/2

Managing processes and managing files.

Why: 'Managing processes' repeats the question and earns nothing; 'managing files' is file management, not process management, so it is not credited.

3Describe2 marksUser Management Swap Remove

A school laptop is shared by several teachers.

Describe the purpose of giving each teacher their own user account on the laptop.

[2 marks]
Mark scheme

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

  • Each teacher can keep their own files/desktop separate (1) so other teachers cannot see or change their work (1)
  • Each teacher's work is saved under their own account (1) so they can find their files easily when they log in (1)
  • The operating system knows which teacher is logged in (1) so it can apply the right access rights to that person (1)
  • Each teacher can set up their own desktop/settings (1) so the laptop is set up the way they like to work (1)

Do not accept responses about the laptop running faster or having more storage because it has more accounts.

Do not accept 'so they can log in' without saying why having separate accounts helps.

Example answers and how they were marked
Full marks2/2

Each teacher's files are stored separately, so other teachers cannot open or change their work.

Why: Separate files for each account (1) and other teachers kept out of that work (1).

Some marks1/2

So that each teacher has their own files.

Why: First point of separate files per account (1), but no development of what this achieves (0).

No marks0/2

So the laptop runs faster because each teacher has their own account.

Why: Gives speed as a purpose of user accounts, which is not correct for user management; no creditworthy point.

4Explain2 marksPeripheral Management Swap Remove

A new printer is connected to a computer.

Explain the purpose of a device driver.

[2 marks]
Mark scheme

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

  • It allows the operating system/OS to communicate with the device/printer (1) because it translates the commands into signals the device understands (1)
  • It contains/sends the instructions/commands needed by a particular device (1) so the device carries out the correct actions (1)
  • It controls the device/printer (1) by sending commands/signals to it (1)
  • Different devices need different commands (1) so each one needs its own driver to work with the operating system (1)

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

Do not accept 'it drives/controls the device' on its own without saying how, e.g. by sending commands/signals.

Do not accept hardware/a physical device (a device driver is software).

Do not accept 'it connects the printer to the computer' or 'it installs the printer' without saying that it provides the instructions/commands for the device.

Example answers and how they were marked
Full marks2/2

It allows the operating system to send commands to the printer because it translates them into signals that the printer understands.

Why: Linked point (1) and reason (1).

Some marks1/2

It contains the instructions that the printer needs.

Why: Point (1) but no linked reason.

No marks0/2

It is a piece of hardware that connects the printer to the computer.

Why: Misconception: a device driver is software, not hardware, and saying it connects the printer is not accepted without saying it provides the instructions/commands.

5Explain2 marksPurpose & Function of Operating Systems Swap Remove

A computer stores many files on its hard drive.

Explain one reason why an operating system needs file management.

[2 marks]
Mark scheme

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

  • The operating system keeps a record of where each file is stored (1) so files can be found/retrieved later (1)
  • The operating system keeps files in separate storage locations (1) so files are not overwritten/lost (1)
  • The operating system allocates files to folders/directories (1) so it can keep track of the files stored on the disk (1)
  • The operating system deletes/moves files (1) so storage space is freed/reused (1)

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

Do not accept 'it manages files'/'it organises files' without expansion as to what is managed or organised.

Do not accept 'so files are managed/organised' as the linked reason.

Do not accept 'so the computer works' as the linked reason.

Example answers and how they were marked
Full marks2/2

The operating system keeps a record of where each file is stored on the disk, so a program can find and open the file later.

Why: Linked point (1) and reason (1): record of file location and retrieval.

Some marks1/2

The operating system keeps a record of where each file is stored.

Why: Point (1) only; no linked reason given.

No marks0/2

The operating system manages the files so the files are managed.

Why: Repeats the question ('manages files') and the expansion restates the point ('so the files are managed'); no creditworthy point under the Do not accept lines.
