Explanation
### Why this is right
The deciding difference is how each computer represents the information it works with. Analog computers use values that can change smoothly, digital computers use separate, distinct values, and hybrid computers use both approaches.
### The concept
A **continuous quantity** can take any value within a range, such as a changing temperature or pressure. An analog computer represents such information through a physical change, such as a changing voltage. A **discrete value** belongs to a set of separate choices; digital computers process these values, commonly represented internally as binary digits, or bits. A hybrid computer combines analog processing, which can handle changing physical measurements, with digital processing, which can handle distinct values and calculations. The key is the kind of representation and processing used, not the computer’s size or purpose.
### The pairs
| Item | Matches | Why |
|---|---|---|
| Analog computer | Processes continuously varying quantities | It represents information with smoothly changing values, such as a voltage that tracks a changing measurement. |
| Digital computer | Processes discrete values | It works with distinct values rather than a continuously changing signal. |
| Hybrid computer | Combines analog and digital processing | It uses both continuous-signal processing and processing of separate values. |
### Terms
- **Analog computer**: A computer that represents information using continuously changing physical values.
- **Digital computer**: A computer that represents and processes information as separate, distinct values.
- **Hybrid computer**: A computer that combines analog and digital methods.
- **Continuous quantity**: A measurement that can vary smoothly within a range.
- **Discrete value**: One distinct value from a set of separate possibilities.
- **Processing**: Working with information to represent it, calculate with it, or produce a result.
### Remember
If the values vary smoothly, think analog; if they are separate, think digital; if both are used, think hybrid.
