pillar a: computer science
Explore the fundamental principles of Computer Science. Master computational thinking, efficient algorithm design, data representation, and diverse programming paradigms to build the logic behind the digital world.
Computer Science is the study of computation and data through computational thinking. This method uses abstraction, decomposition, pattern recognition, and the creation of efficient algorithms. All data is processed as binary and organised into data structures. These principles are applied via programming - using various paradigms and tools like debuggers - to create code that translators (compilers or interpreters) convert into machine-executable instructions.
This is the brain work behind every great piece of software. It’s a powerful method for solving complex problems by breaking them down into steps that a computer can actually carry out.
Computers are only as smart as the instructions we give them. This strand explores how we design those instructions to be fast, efficient, and logically sound.
Information—from text and images to social media feeds—must be translated into a language machines understand: binary.
