Question

in the 1960s, researchers looked for ways to make computer usage more ____ by developing a time - sharing system. private profitable efficient affordable

Explanation:

Time - sharing systems allow multiple users to interact with a computer system simultaneously. This leads to better utilization of computer resources. Efficiency in computer usage is enhanced as the system can handle multiple tasks and users without long waiting times. Private (relating to personal or non - shared) is incorrect as time - sharing is about sharing. Profitable (relating to making money) is not the main focus of time - sharing in terms of the description of computer usage improvement. Affordable (relating to cost) is not directly related to the core concept of time - sharing improving computer usage in terms of resource utilization.

Answer:

C. efficient
