A(n) is a step-by-step direction for performing a specific task, which is written in a language the computer can understand. servercachearrayprogram

The correct answer is D (a program).

Explanation:

We know that a server is a program that can access a variety of different databases, a cache stores data, and an array is a collection of data. None of these definitions accurately match the one in the prompt, thus making D the only correct (and reasonable) answer.

I hope I helped! :)

Explanation:

A computer program is an incredibly big set of instructions that are based on decision making and that combine themselves in different amounts of combinations to create a different product. So, in other words, computer programs are probabilistic tree schemes based on the possible combinations they can have to present different results. They are all written in code lines and the bugs or errors are misspellings of these lines propitiating that they don't create the expected result for that combination.
