Shade in the A or B circle for each question.

1. A student wants to classify a word processor. Which answer is correct?

A System software, because it is installed on the computer

B Application software, because it helps the user do a task (writing documents)

2. Which program is system software?

A A video game, because it uses the computer's processor

B An operating system, because it manages the computer's hardware and resources

3. Which statement about an antivirus program is correct?

A It is system software, because it protects and maintains the computer itself

B It is application software, because the user chooses to install it

4. Which is the best way to classify a program?

A Ask whether it serves the computer's own needs or a task the user wants done

B Ask whether it is free or paid for

5. Backup software copies files so they can be restored if the originals are lost. How should it be classified?

Answer Key

Classifying software as system or application

Section A: Quick Questions

B — Application software, because it helps the user do a task (writing documents)

B — An operating system, because it manages the computer's hardware and resources

A — It is system software, because it protects and maintains the computer itself

A — Ask whether it serves the computer's own needs or a task the user wants done

A — System software, because it is a utility that maintains the computer's data

Section B: Match the Pairs

Windows 11 (operating system) → System software, because it manages the computer's hardware and runs other programs rather than doing a user task

Microsoft Word (word processor) → Application software, because it helps the user complete a task they want done: writing and editing documents

Antivirus and backup tools look after the computer itself, so they are classified as system software → antivirus = 'system software' # because it protects the computer

A game is something the user wants to do for fun, so it is classified as application software → game = 'application software' # because it does a user task

Antivirus = application software because the user chooses to install it → Wrong reason. Antivirus is system software because it protects and maintains the computer itself. Who installs it does not decide the type.

Word processor = system software because it runs on the operating system → Wrong classification. A word processor is application software because it helps the user write documents. Running on the OS does not make it system software.

Section C: Definitions

system vs application — Ask who the program serves: the computer itself (OS, antivirus, backup) is system software; a task the user wants done (word processor, game) is application software. Justify with 'because'.

Section D: Fill in the Blanks

IF serves = "computer" THEN
    category ← "system"
ENDIF

IF serves = "user" THEN
    category ← "application"
ENDIF

OUTPUT "Backup tools are system software"
OUTPUT "because they protect the computer"

OUTPUT "A game is application software"
OUTPUT "because the user wants to play"

IF serves = "user" THEN
    category ← "application"
ENDIF

Section E: Spot the Error

C — Antivirus software looks after the computer itself, so it is system software, not application software. The line should be kind = "system".

D — A word processor does a task the user wants done (writing a letter), so it is application software. The line should be kind = "application".

D — Both outcomes return "system", so a game would be classed as system software. The last line should return "application" for programs that do not serve the computer.

C — A single = assigns a value. A comparison needs ==. It should be if serves == "computer":.

B — The operating system manages the computer's own hardware and resources, so it serves the computer, not the user. The line should be serves = "computer".
