Final answer:
A numeric keypad is used to input a PIN, featuring numbered buttons and allowing for quick, efficient data entry. In the broader development of technology, the microprocessor significantly advanced computers' ability to process large information amounts.
Step-by-step explanation:
The device used to input a PIN is c) A numeric keypad. This input device features a set of buttons with numbers typically ranging from 0 to 9, and sometimes including additional buttons for operations such as 'Enter' or 'Cancel'. Numeric keypads are commonly found on ATMs, security systems, and computer keyboards. They enable users to enter numerical information quickly and efficiently, which is essential for processes that require precise data entry, like entering a personal identification number (PIN).
In the context of the history of technology, a significant development that enabled digital computers to efficiently process large amounts of information was the invention of the microprocessor. The microprocessor serves as the brain of modern computers, allowing for complex computations and logical operations to be executed at high speeds, thus handling vast quantities of data effectively.d
