Bits, bytes, and number systems

Computers store all data as binary, so every file is ultimately a pattern of 000s and 111s. One binary digit is a bit, and 888 bits make 111 byte.
Step-by-step lessons covering OCR GCSE Computer Science Data storage for GCSE Computer Science. Each lesson works through exam-style questions in Component 01 and Component 02 format. Build strong foundations in binary, logic and core programming constructs before moving on to the more complex algorithm design and evaluation questions.
