1Short recall2 marksFile Management Swap Remove

A user stores documents on a computer.

Give two tasks that file management allows the user to perform on a file.

[2 marks]
Mark scheme

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

  • Creating a file (1)
  • Opening a file (1)
  • Naming/renaming a file (1)
  • Saving a file (1)
  • Copying a file (1)
  • Moving a file (1)
  • Deleting a file (1)

Allow rename for renaming

Allow cut and paste for moving

Allow remove for deleting

Do not accept organising files or managing files on their own, without a named task

Do not accept file management, working with files, process management, user management

Example answers and how they were marked
Full marks2/2

Renaming a file and deleting a file.

Why: Names renaming (1) and deleting (1), two file management tasks.

Some marks1/2

Saving a file.

Why: Names one file management task (1).

No marks0/2

Organising files and managing processes.

Why: Organising files without a named task is not credited, and process management is another operating system function, not a task performed on a file.

2Short recall1 markSoftware Basics Swap Remove

A computer system runs both an operating system and utility software.

State one difference between an operating system and utility software.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • The operating system is needed/essential for the computer to run / utility software is optional (1)
  • The operating system manages the hardware/users/resources / utility software performs housekeeping tasks that keep the system running efficiently (1)
  • The operating system provides a platform for other software to run / utility software carries out extra/specific tasks (1)
  • Each utility program performs one specific task / the operating system carries out many different management tasks (1)
  • Utility software is often packaged with the operating system but can also be bought separately (1)

Do not accept answers that only give an example of each (e.g. Windows, anti-malware) without stating a difference.

Do not accept the operating system is hardware.

Example answers and how they were marked
Full marks1/1

The operating system is needed for the computer to work, but the utility software is optional.

Why: States a creditworthy difference: essential versus optional (1).

No marks0/1

Windows is an operating system and anti-malware is utility software.

Why: This only gives an example of each and does not state a difference, so no mark is awarded.

No marks0/1

The operating system is hardware and the utility software is software.

Why: The operating system is software, not hardware, so the answer contains no creditworthy difference.

3Describe2 marksUtility Software Swap Remove

A student has a large number of photographs stored on a computer.

Describe the purpose of data compression software.

[2 marks]
Mark scheme

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

  • Makes a file/files smaller (1) so less storage space is needed on the disk (1)
  • Reduces the size of the data (1) so it takes less time to upload/download/transfer the file (1)
  • Compresses files/folders into a single file (1) so an attachment is under the size limit for email (1)
  • Reduces the size of the files (1) so more of them fit onto a storage device/backup media (1)

Do not accept 'it compresses the files' on its own, as this repeats the question.

Do not accept responses about protecting files from malware/viruses or about deleting files.

Example answers and how they were marked
Full marks2/2

It makes the files smaller so that they use less storage space on the computer and more of them fit on the disk.

Why: The point (1) and a linked development giving the benefit (1).

Some marks1/2

It makes files smaller.

Why: This is the point (1) but there is no development of what the smaller size leads to, so only one mark.

No marks0/2

It protects the files from viruses so that they cannot be damaged.

Why: This describes anti-malware software, which the mark scheme does not accept; no creditworthy point is made.

4Explain2 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.
