Utility Software Worksheet: OCR GCSE J277

A GCSE worksheet on utility software for OCR J277 1.5.2: encryption, defragmentation and compression, 23 marks in 40 minutes, with a full mark scheme.

Students read a two-page recap, put it away, then answer a task sheet from memory. The recap covers what utility software is for and the three utilities OCR names, with a fragmented disk drawn before and after, and the misconception about encryption that examiners keep reporting.

What’s inside (6 pages, PDF and editable Word)

• A recap sheet (pages 1 and 2): what utility software is for, then encryption, defragmentation and data compression software, with two exam tips and the encryption misconception set out.
• A task sheet (pages 3 and 4), answered with the recap put away.
• A full mark scheme (pages 5 and 6), with what to accept and what not to accept. It starts on an odd page, so a double-sided print keeps it off the back of a student sheet.

The tasks

1. Defragment the disk: twelve blocks holding three fragmented files. Students fill in one arrangement after defragmentation.
2. Choose the utility software: three situations. Name the right utility for each and justify it in one sentence.
3. Two exam-style questions: why a laptop needs utility software, how encryption protects a stolen laptop, how files become fragmented, why defragmenting helps, and why photographs are compressed before they are emailed.

Why it works in a real classroom

• Recall, not copying. The recap is on its own sheet, so it can be collected before the tasks start.
• It marks what examiners mark. The scheme rejects naming one utility as the purpose of all of them, and “it stops the data being read” for encryption: examiners report both.
• Editable. The Word version is included, so you can change a name, a number or a scenario to suit your class.
• Nothing to set up. Print, hand out, collect. There is nothing to install and nothing to log in to.

You need: a recap sheet and a task sheet per student, each printed double-sided and not stapled together. Keep pages 5 and 6 back; a cut line marks where the mark scheme starts.

Good for: a lesson on systems software, homework after teaching 1.5.2, a cover lesson, or Year 11 revision before Paper 1.
