Data Representation
Learners explore number systems (binary, decimal, hexadecimal), perform binary arithmetic, and understand ASCII for text representation. This topic aligns with CBC competences in data handling and computational logic. It equips Zambian students with skills to convert between number systems and interpret data formats, which are frequently tested in ECZ examinations. Understanding data representation is fundamental for programming, networking, and advanced computer science studies in the Zambian secondary curriculum.
