What examiners said
This question was well answered with many candidates able to answer that digital data was read and processed by a computer. Some candidates stated that humans could not read digital data; humans can but it is more difficult to understand it.
— Examiner report, May/June 2025, 0417/11 Q2(b) (Cambridge)
This question was more challenging than part (b) with some candidates writing that analogue data could not be understood by a computer. Some candidates gave the better answer that it could be used to control devices.
— Examiner report, May/June 2025, 0417/11 Q2(c) (Cambridge)
This question was challenging for candidates. It was pleasing to see responses following the process through and clearly identifying inputs and processes. Weaker responses often gave outputs, for example the ATM asks the user to input their PIN, also some responses went out of context and described the process of taking or depositing money into the bank. The processing of data was nt as well expla...
