Hardware — AS & A Level Computer Science (9618) questions by topic
Explaining lexical analysis during compilation, identifying the largest file size among mixed kibibyte and megabyte options, and completing a table of sensors a navigating robot could use are the kind of tasks this topic sets, across 18 real questions from 2023 to 2025 papers worth 3 to 22 marks.
Explain, describe, identify, complete and convert are the top command words, and convert specifically means correctly moving between binary-prefix units such as kibibytes and kilobytes rather than treating them as equivalent. Because unit-conversion questions punish a single misremembered multiplier, checking a worked answer against instant marking is a fast way to confirm the right base was used throughout.
