What this worksheet teaches

• Identify common software categories: operating system, application, browser.
• Convert between simple units of digital storage - bits, bytes, kilobytes, megabytes.

• Explain the input, process, output cycle using a familiar example such as typing a document and printing it.

How to use this worksheet

The RAM-versus-storage question is where Grade 4 students lose marks, and the fix is a demonstration rather than a definition: open something without saving, cut the power, and show that the work is gone. Do that once and the worksheet answers stop being guesses.

Sample questions from this worksheet

1. Which part controls all activities?
2. Which is a secondary storage device?

Frequently asked questions

Should I let my child answer the internet safety questions from experience?

Yes - those questions work best as a conversation. Ask what they would do before they write, then compare with the answer they choose.

Does my child need a computer to finish this worksheet?

No, it is fully answerable on paper. But the file, folder and storage questions land much better if a laptop is available for a two-minute demonstration.

Is this aligned with school computer syllabuses?

It covers the standard Grade 4 computer-literacy block - the input-process-output cycle, hardware and software, file management, storage units and basic internet safety - which appears in most school ICT curricula.
