A computer's secondary memory would be used to look at the files created on the home screen of the computer.
Option A is the correct answer.
A computer is an electronic device that is used to do various kinds of operations automatically.
Now, Secondary memory can be utilized to store the data or information which can be instantly recovered.
It is also known as backup memory. USB drives, hard disk drives, optical drives, etc. are some examples of secondary memory.
Therefore, the task of locating the files in the computer is to be done by using the computer's secondary memory. So option A is true.

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation. Relevant geometry equations: Volume
Answer:
import java.io.*;
public class Main {
public static void main(String[] args) throws IOException {
double baseLength = 0, baseWidth = 0, pyramidHeight = 0;
Object[] volume;
volume = calcPyramidVolume(baseLength, baseWidth, pyramidHeight);
}
public static Object[] calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight) {
double area = calcBaseArea(baseLength, baseWidth);
double volume = baseLength * baseWidth * pyramidHeight;
return new Object[]{volume, area};
}
public static double calcBaseArea(double length, double width) {
return length * width;
}
}
Explanation:
The problem is flawed because it is completely inefficient for one to create two separate methods to calculate the volume and the area when they can be done at once.
The second problem is that it was never specified whether to return something from the calcBaseArea method.
I assumed it required it, so it is not advisable to initiate the method as a double, but rather create it as an Object so that it can return two values: the volume and the area.

To what extent do you agree with the assertion that “Collection development begins with community analysis”. (Give reasons to buttress your answer).
I completely agree that Collection development begins with community analysis; this is because the goal of collection development is to meet the information needs of everybody in a user community.
Collection development is a term used to describe the gathering and maintenance of library materials and resources such as textbooks, audiovisuals, and electronic materials for the community users to assess.
Collection development involves many processes, but it is better to begin with community analysis to know what type of resources, information, or materials is needed in that community.
It is from the community analysis and conclusion reached; other steps can then be followed sequentially.
Also, note that through community analysis, one can determine the present users of the library and their major interests.
Hence, in this case, it is concluded that community analysis is vital in the collection development in library and information management.

Explanation:
Write a method named removeDuplicates that accepts as a parameter a List of integers, and modifies it by removing any duplicates. Note that the elements of the list are not in any particular order, so the duplicates might not occur consecutively. You should retain the original relative order of the elements. Use a Set as auxiliary storage to help you solve this problem.
For example, if a list named list stores [4, 0, 2, 9, 4, 7, 2, 0, 0, 9, 6, 6], the call of removeDuplicates(list); should modify it to store [4, 0, 2, 9, 7, 6].
The method is an illustration of loops or iteration.
Loops are used to carry out repetitive operations.
The removeDuplicates method in Python is as follows, where comments are used to explain each line.
#This defines the method
def removeDuplicates(list):
#This initializes the output list
outputList = []
#This iterates through the list
for i in list:
#All elements not in the output list, are appended to the output list
if i not in outputList:
outputList.append(i)
#This returns the output list
return str(outputList)
At the end of the method, the new list contains no duplicates.
