A school is developing a program to keep track of information about students and their class schedules. In which of the following instances would a data abstraction be most helpful? A. The program includes individual variables to store the names of each student rather than a single list of students.

B. A program includes multiple comments that could be combined into a single comment

C. A program includes repeated programming statements that could be moved inside a loop

D. A program includes repeated code that could be moved inside a function.

D

Explanation: A doesn't make sense, B doesn't either.

However you're left with C and D. In this case I can understand if you picked C, but I picked that and got the answer wrong.

D makes sense since data abstraction means to simplify the code to make it easy to read and point out details while removing other components.

A function allows one to understand the intention of the code by its name and thus it makes it easier to read.

Therefore, I suggest D.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
