Key Terms Precision Quiz - GCSE Computer Science

The Idea

Why Precision Matters

The Chief Examiner has repeatedly highlighted a common problem: students give vague, generic definitions and score zero. The mark scheme requires specific technical keywords to award marks. A definition that sounds roughly correct but misses the key terms will not earn you a single mark.

Examiner Feedback: “Students who give vague definitions like ‘it connects things’ or ‘it stores stuff’ consistently score 0 marks. The mark scheme requires precise technical language, not everyday English.”

Here is a concrete example to show you the difference:

Example: “Define a router” [1 mark]

Bad Answer (0 marks)

“A router connects devices together”

Good Answer (1 mark)

“A router forwards data packets between different networks using IP addresses to determine the best route”

The bad answer describes what a switch or a cable does. The good answer uses the precise terms data packets, different networks, and IP addresses — exactly what the mark scheme requires.

This quiz will train you to recall the exact mark-scheme definitions for 60 key terms across all Paper 1 topics. You type your definition, then compare it against the mark scheme and honestly self-assess. Terms you struggle with are saved so you can retry them later.
