KS4 COMPUTER SCIENCE
GCSE Computer Science (OCR Board)
Overview
Component 01: Computer systems
Introduces students to the central processing unit (CPU), computer memory and storage, data representation, wired and wireless networks, network topologies, system security and system software. It also looks at ethical, legal, cultural and environmental concerns associated with computer science.
Component 02: Computational thinking, algorithms and programming
Students apply knowledge and understanding gained in component 01. They develop skills and understanding in computational thinking: algorithms, programming techniques, producing robust programs, computational logic and translators.
