Concept:Computers are classified by the way they handle data — as continuous signals or discrete numbers.
Explanation:An analogue computer processes data that changes smoothly and continuously.
It uses physical quantities like voltage, current, or resistance to represent values.
For example, it can measure a moving object’s position or a substance’s changing temperature without jumping between steps.
A digital computer, in contrast, only handles discrete values such as
0 and
1.
Mainframe computers and microcomputers are both digital, so they do not fit the description.
Therefore, the computer type that represents data as variable and continuous values is the analogue computer.
Answer:A. Analogue computer
