Final answer:
The FOSDIC (Film Optical Sensing Device for Input to Computers) was the device in the 1950s that enabled computerized systems to efficiently process large amounts of information by transferring data from paper to microfilm.
Step-by-step explanation:
A computerized system tracks film and folders with a device that made it possible for digital computers to efficiently process large amounts of information. In the 1950s, such a device was critical for operations like those of the U.S. Census Bureau, which needed to transfer data from paper questionnaires to microfilm for rapid processing by computers. This device is known as the FOSDIC (Film Optical Sensing Device for Input to Computers), which was pivotal in digital data management and processing during that era.
