Paper 1 — Theory Fundamentals

75 marks · 1 hour 30 minutes · 50% of the AS Level No calculators. All questions compulsory, answered on the question paper.

All eight topics are written. Each has a Jigsaw (syllabus mapped to past questions) and a Pack (the same content as timed Q&A). If you have not met the system yet, read the architecture note first.

Topics

1 · Information Representation

Number systems, base conversion, binary arithmetic, BCD, character sets, images, sound, compression. 168 concepts · 142 Q&A — contains 1.1.3, the single most-asked bullet in the paper.

2 · Communications

Networks, the internet, protocols, transmission. 199 concepts · 157 Q&A — the widest topic in the paper.

3 · Hardware

Components, embedded systems, storage, buffers, RAM/ROM, sensors, logic gates. 94 concepts · 87 Q&A

4 · Processor Fundamentals

Von Neumann, registers, buses, the F–E cycle, interrupts, assembly, bit manipulation. 122 concepts · 114 Q&A

5 · System Software

Operating systems, utilities, program libraries, translators, IDEs. 109 concepts · 107 Q&A

6 · Security, Privacy and Data Integrity

Threats, protection, encryption, digital signatures, validation and verification. 105 concepts · 110 Q&A

7 · Ethics and Ownership

Professional ethics, copyright, licensing, artificial intelligence. 83 concepts · 82 Q&A

8 · Databases

File-based limitations, relational models, E-R diagrams, normalisation, DBMS, SQL. 155 concepts · 148 Q&A — the largest single topic.

Reading the paper itself

What the paper looks like

Topics are examined roughly in syllabus order, one question per topic, with Databases almost always a whole multi-part question of 6–15 marks. Topic 4 reliably carries the assembly-language trace table, and topic 3 the logic circuit. The command word decides the tariff: state is 1 mark per point, describe is point-plus-expansion, explain needs a consequence, and justify usually puts all the marks in the reasoning rather than the choice.

Five sub-topics with no 9608 fallback

These are new in 9618, so no old-syllabus questions exist to practise on: AI (7.1.5) · embedded systems (3.1.2) · PROM/EPROM/EEPROM (3.1.7) · bit manipulation (all of 4.3) · IDE features (5.2.4). All five are examined regularly. The !info inferences in those sections carry more weight than anywhere else in the vault.
