1Short recall2 marksSoftware Basics Swap Remove

Every computer system needs an operating system.

State two functions of an operating system.

[2 marks]
Mark scheme

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

  • File management (1)
  • Process management (1)
  • Peripheral management (1)
  • User management (1)

Allow 'managing files', 'managing processes', 'managing peripherals', 'managing users'.

Do not accept examples of utility software, such as anti-malware, backup or defragmentation, as these are not functions of the operating system.

Do not accept 'runs/loads the programs' on its own.

Example answers and how they were marked
Full marks2/2

File management and process management.

Why: Two creditworthy functions from the list, one mark each (1) + (1).

Some marks1/2

It does file management and it loads the programs that the user wants to run.

Why: File management earns one mark (1); 'loads the programs' is not one of the listed functions, so no second mark.

No marks0/2

Anti-malware and backup.

Why: These are examples of utility software, not functions of the operating system, so no mark is awarded.

2Short recall2 marksUser Management Swap Remove

A user must log in before using a computer.

State two methods, other than a password, that an operating system can use to authenticate a user.

[2 marks]
Mark scheme

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

  • Fingerprint scan (1)
  • Face recognition (1)
  • Iris/retina scan (1)
  • Voice recognition (1)
  • Palm print/vein scan (1)
  • Smart card (1)
  • Security token (1)
  • Authenticator app (1)

Allow one-time passcode (OTP) for authenticator app.

Do not accept password (given in the question).

Do not accept username/user ID (it identifies the user but does not authenticate them).

Do not accept 'two-factor authentication' on its own (it is a combination of methods, not a method itself).

Do not accept 'encryption'.

Example answers and how they were marked
Full marks2/2

Fingerprint scan and a smart card.

Why: Fingerprint scan (1) and smart card (1) are two accepted methods.

Some marks1/2

Fingerprint scan and a username.

Why: Fingerprint scan (1); username is not accepted because it does not authenticate the user.

No marks0/2

A username and two-factor authentication.

Why: Username is not accepted because it does not authenticate the user, and two-factor authentication alone is not accepted because it is a combination of methods.

3Explain2 marksUser Management Swap Remove

A college computer room has computers that many students share.

Explain one reason why each student has their own user account.

[2 marks]
Mark scheme

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

  • Each student's files/work are kept separate (1) because the operating system checks the access rights of the user who is logged in, so other students cannot open/see/change/delete them (1)
  • A student's own settings/desktop are loaded when they log in (1) because the operating system stores settings for each user account (1)
  • Students cannot install software or change system settings (1) because their user account does not have administrator privileges (1)

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

Award 1 mark for a correct point on its own, even if no linked reason is given.

Allow answers about personal settings/desktop/wallpaper being saved/loaded for that user.

Allow answers about a standard user account not having administrator privileges.

Do not accept 'so they can log in' on its own, because logging in is what the user account is for.

Do not accept 'so they can save files/work' on its own without saying other students cannot access their files.

Do not accept 'so the computer is secure' without saying what is protected or who is kept out.

Do not accept answers about stopping viruses or making the computer run faster.

Example answers and how they were marked
Full marks2/2

Each student has their own account so their files are kept separate from everyone else's. When they log in, the operating system checks their access rights, so another student cannot open or delete their work.

Why: Linked point (1) and reason (1): files/work are kept separate because the operating system checks the logged-in user's access rights, so other students cannot open/change/delete them.

Some marks1/2

Each student's work is kept separate so they can save more files on the computer.

Why: Correct point (1) that work is kept separate, but the reason 'so they can save more files' is not linked to user management/access rights and does not say other students cannot access the files, so no second mark.

No marks0/2

So that the computer does not get a virus from other students.

Why: No credit: stopping viruses is not a reason for separate user accounts, and no user-management point or linked reason is given.
