1Describe2 marksPurpose & Function of Operating Systems Swap Remove

A laptop stores many files on its hard disk.

Describe one way the operating system manages the files on the laptop.

[2 marks]
Mark scheme

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

  • Keeps a record/index of where each file is stored on the disk (1) so that the file can be found and opened when it is needed (1)
  • Allocates each file to a folder/directory (1) so that files used for the same purpose are kept together (1)
  • Decides where on the disk each new file is written (1) so that it does not overwrite an existing file (1)
  • Allocates space on the disk for a file (1) so that the file has somewhere to be saved (1)

Allow 'files are organised into folders so that they are easy to find', with the folder point (1) and its purpose (1).

Do not accept responses that only state that the operating system 'organises' or 'controls' the files, with no way of doing it given.

Do not accept 'stores the files' or 'saves files to the disk' without a way of doing it.

Do not accept responses about backing files up, or about the amount of storage space left on the disk.

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 that the file can be found and opened again later

Why: Linked point (1) - keeps a record of where each file is stored - and development (1) - so the file can be found later.

Some marks1/2

The operating system puts the files into folders.

Why: Gives the point that each file is allocated to a folder (1) but no linked development about why files are grouped.

No marks0/2

The operating system backs up the files to the cloud so that they are not lost.

Why: Backing up is not file management on this specification, so no point or development is credited.

2Explain2 marksProcess Management Swap Remove

A user opens a web browser.

Explain what the operating system does to get the browser's process ready to run.

[2 marks]
Mark scheme

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

  • A process is created for the program (1) so that its instructions can be loaded into RAM (1)
  • The process is put into the ready state (1) so that it can wait for the CPU to become available (1)
  • The operating system adds the process to a queue of ready processes (1) so the scheduler can choose it when the CPU is free (1)
  • The operating system allocates the resources the process needs (1) so that it can start running when it is given CPU time (1)

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

Allow 'main memory' for RAM.

Do not accept 'the browser is downloaded/loaded from the internet'.

Do not accept 'the program is run immediately on the CPU' without the ready step.

Example answers and how they were marked
Full marks2/2

It creates a process and loads the browser's instructions into RAM, then puts the process in the ready state to wait for CPU time.

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

Some marks1/2

It moves the program into RAM.

Why: A correct point (1) but no linked reason about the process being made ready.

No marks0/2

It runs the program straight away on the CPU.

Why: This describes the running state, not making the process ready, so no credit.
