Cambridge O Level Computer Science 2210 – Paper 1: Theory

The University of Cambridge O Level Computer Science 2210 Paper 1, focused on Computer Science Theory, is a core component of the course, assessing students’ understanding of fundamental computing principles. The exam lasts 1 hour and 45 minutes and carries a total of 75 marks, evaluating students’ theoretical knowledge and problem-solving skills in various computer science domains.

This compulsory paper includes short-answer and structured questions, which are derived from Section 1 of the syllabus content. The questions are designed to test students’ comprehension of theoretical concepts, problem analysis, and application of knowledge to real-world computing scenarios.

A key objective of Paper 1 is to assess students’ grasp of computer systems, networks, data representation, hardware and software, security, and ethical issues. It also evaluates their ability to interpret logic circuits, understand database management, and apply fundamental computing principles effectively.

Key Aspects of Paper 1:

• The questions do not require students to write code but focus on theoretical and conceptual understanding.
• Students must be familiar with computing terminology, fundamental hardware components, and software types.
• The paper includes questions that assess problem-solving techniques, such as tracing algorithms, understanding binary calculations, and analyzing system architectures.
• Unlike Paper 2, which emphasizes practical programming, Paper 1 focuses on the underlying principles of computation and system design.
