Which of the following statements is not correct?
AA computer can process only digital data
BA computer can analyse both quantitative and qualitative data
CAppropriate software is required for processing the data
DA computer can process digital as well as analogue signals ✓ Correct
Correct answer: (D) A computer can process digital as well as analogue signals
Explanation
The statement that a computer can process analogue signals directly is the incorrect one, since a digital computer works only on discrete digital data.
Saying a computer can process only digital data is a true description of its nature.
It can indeed analyse both quantitative and qualitative data once each is coded in digital form.
Suitable software is genuinely required before raw data can be processed into results.
Purely analogue machines form a separate, now rarely used category.
An analogue quantity reaches a digital computer only after an analogue-to-digital converter turns it into numbers.
