Example of counting device
- Shepherds in ancient times used pebbles as a counting device to track their sheep.
- The earliest counting devices were notches on bones or wood.
number cruncher 🔊
Meaning of number cruncher
A colloquial term for a device or person performing large amounts of calculations.
Key Difference
A number cruncher can refer to either a machine or a person, while a calculator is strictly a device.
Example of number cruncher
- The financial analyst was known as a human number cruncher for his speedy calculations.
- Supercomputers act as massive number crunchers for scientific research.
digital calculator 🔊
Meaning of digital calculator
An electronic calculator that displays results on a digital screen.
Key Difference
