Humans, processors, and language levels

Programs are usually written as source code, which is the program text written by the programmer before translation. Processors do not read that directly; they only execute machine code, which is binary instructions.
Step-by-step lessons covering AQA GCSE Computer Science Classification of programming languages and translators for GCSE Computer Science. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Build strong foundations in binary, logic and core programming constructs before moving on to the more complex algorithm design and evaluation questions.
