Final answer:
With multiprogramming, time is used productively to optimize CPU usage by running processes efficiently. Unlike space or money, time specifically refers to the CPU time being utilized effectively. In a postindustrial society, information is considered the most important commodity.
Step-by-step explanation:
With multiprogramming, time is used productively. Multiprogramming is a method of running multiple programs on a single processor by managing the use of the CPU. This approach efficiently utilizes CPU time by running a process while another process is waiting for I/O operations to complete, thus optimizing the use of processor time and enhancing system throughput.
In the context of the given options: space refers to memory usage which is not directly optimized by multiprogramming, money savings are a broader consequence and not specific to multiprogramming's functionality, whereas time specifically refers to CPU time being used efficiently which is the fundamental advantage provided by multiprogramming.
The most important commodity in a postindustrial society is information. As society has evolved from an industrial focus to a knowledge and services base, the value of information has increased significantly. The rapid access to and exchange of information drives innovation, decision-making, and economic growth in postindustrial societies.
