The full Cambridge IGCSE Computer Science course: how computers represent and send data, how hardware and software work, the internet, security and emerging technologies, and how to design algorithms, write programs, query databases and build logic circuits.
Lesson 1 is free to try. The other 80 lessons in Computer Science and its exam practice are for schools on RudimentaryLabs.
How a machine that only understands on and off can store numbers, text, pictures and sound.
How data is packaged, sent, checked for errors and kept secret on its journey between devices.
The processor, input and output devices, storage and the network parts that make a computer work.
Operating systems, interrupts, programming languages and the tools that turn code into something a computer can run.
How the web works, what digital currency is, and how to stay safe from online threats.
Automated systems, robots and artificial intelligence, and what they mean for the world.
Breaking problems down, designing step-by-step solutions, and testing that they really work.
Turning algorithms into working programs with variables, loops, subroutines, arrays and files.
Storing records in a table and asking questions of them with SQL.
How logic gates combine 1s and 0s to make decisions, and how to design circuits from a problem.
