Unit 3 — Computers

Title: GCSE Computer Science (Edexcel 1CP2) – Unit 3: Computers – Full Topic Bundle

Covers computer systems from the CPU up: The CPU and Fetch-Decode-Execute Cycle, CPU Performance and Von Neumann Architecture, Primary Storage (RAM and ROM), Secondary Storage, Embedded Systems, Operating Systems, and Utility Software.

Each of the 7 topics comes complete with teacher slides, worksheet, exam-style homework with mark schemes, and a full lesson plan — ready to teach without any further prep.

Strong focus on the comparison/evaluation-style questions GCSE papers favour (e.g. comparing storage types, justifying CPU specifications for a scenario), with tiered Support/Core/Extension tasks so the same lesson stretches your full ability range.
