The Atanasoff-Berry Computer (ABC) introduced which of the following capabilities for modern computers?

The Atanasoff-Berry Computer (ABC) is significant in the history of computing because it introduced key concepts that laid the groundwork for modern computers. Among these, the ability to perform parallel processing and to separate memory functions were crucial advancements.

The ABC utilized a separation of tasks into distinct functions, which allowed for the simultaneous processing of information. This architecture was innovative at the time and contributed to the development of later computers that could efficiently manage multiple tasks at once. Furthermore, the ABC's method of using separate memories for data and instructions influenced future designs, making it possible for computers to handle more complex operations and store more information.

This foundation of parallel processing and distinct memory functions is indicative of how modern computers operate today, emphasizing speed and efficiency in processing data. In contrast, advancements like improved graphics processing, wireless connectivity, and user interface design are features that emerged much later in the evolution of computers and were not part of the innovations introduced by the ABC.
