Concept:The first calculating machine was the Pascaline, a mechanical device invented by Blaise Pascal.
Explanation:In data processing history, the abacus is considered an early manual counting tool, not a machine.
Blaise Pascal created the Pascaline in 1642, and it is widely accepted as the first mechanical calculating machine.
Punched cards appeared later and were used mainly for data storage and input, not for performing calculations.
The term "digital" refers to modern electronic computing systems, which were developed much later.
Thus, the correct option names the inventor, Pascal, as the answer.
Answer:B. pascal
