Complete AQA GCSE Computer Science 8525 3.4 unit: 9 lessons, logic gate circuits, work and homework booklets, 4 assessments with mark schemes.

Everything you need to teach AQA 3.4 Computer Systems, checked against the specification. Every logic circuit, Boolean expression and truth table is drawn and calculated consistently, so the slides, booklets and mark schemes always agree.

9 lessons (171 editable PowerPoint slides)

1. Logic Gates (AND, OR, NOT, XOR)
2. Logic Circuits (up to three inputs, truth tables and Boolean expressions)
3. Hardware and Software
4. Software Classification (operating system functions and utility programs)
5. Programming Languages (high-level, assembly and machine code)
6. Translators (compilers, interpreters and assemblers)
7. Systems Architecture (Von Neumann, CPU components, buses, Fetch-Execute, cache levels and performance)
8. Memory and Storage (RAM, ROM, magnetic, solid state, optical and cloud)
9. Embedded Systems

Every lesson includes

• Learning objectives and a retrieval Do Now with answers
• Clear teaching slides with diagrams, tables and worked examples
• Practice tasks with answer slides
• AQA-style exam questions with a mark scheme
• A Success Check quiz with answers and a reflective plenary
• Teacher notes on every slide

Work booklet (24 pages) and homework booklet (16 pages), each with answers
Drawing gates and circuits, completing truth tables, writing Boolean expressions, sorting activities, matching, ordering the Fetch-Execute cycle, scenario questions and exam practice, plus key facts, a glossary and a checklist.
