which of the following are applicable to servers? group of answer choices make dns requests requires special software respond to information requests display web documents
DNS servers manage which server a user will access when they enter a domain name into their web browser by converting requests for names into IP addresses.
Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers are the four categories into which all DNS servers fall. Domain name system, or DNS, converts a domain name into an Internet Protocol (IP) address. In light of this, the DNS converts IP addresses into a hierarchy of domain names. Internet Protocol (IP) addresses are translated into domain names during a reverse DNS lookup. Without DNS servers, the internet would not function at all. It is their job to convert domain names into IP addresses. Computers then identify and connect to those web servers using those IP addresses, directing users to the appropriate websites.

The compare function that sorts numeric values in ascending order is: function ascending(a, b) { return a - b; }.
What is compare function?The compare function is a function used to compare two values or expressions. It is used to determine whether the two values or expressions are equal, less than, or greater than one another. It is commonly used in programming languages to compare strings, numbers, and objects. It can also be used to compare logical values, such as true or false.
This function takes two parameters, a and b, and returns the difference between them (a - b). This subtraction results in a negative value if a is less than b, and a positive value if a is greater than b. Therefore, when sorting numeric values in ascending order, the parameter with the smallest numerical value will be placed first.

What is class?
Class in computer science is a template or blueprint that is used to create objects. It is the basis for object-oriented programming (OOP). A class encapsulates data and functions that can be used to create objects of the same type. The data and functions within the class are called members. The members of a class can be public, meaning they are accessible from other classes, or private, meaning they are only accessible within the class. Classes also have a constructor, which is a function that is used to create objects from the class. Classes can have inheritance, meaning a class can inherit data and functions from another class. Inheritance is used to create more specific classes from more general classes. Classes are an important part of programming, providing a way to structure data and create objects.

T or F: When writing formulas for spreadsheets in Excel, you do NOT need to pay attention to or worry about the order of precedence.
When writing formulas for spreadsheets in Excel, you do NOT need to pay attention to or worry about the order of precedence is False.
Formulas for spreadsheets in ExcelOrder of precedence is important to consider when writing formulas for spreadsheets in Excel.Precedence determines in which order mathematical operations are performed, and incorrect precedence can lead to incorrect results.It is important to pay attention to parentheses and operator precedence when writing formulas.When writing formulas for spreadsheets in Excel, it is important to pay attention to and understand the order of precedence. The order of precedence refers to the order in which Excel evaluates and calculates functions and operations in a formula. This is important because it can determine the outcome of the calculation.For example, in the formula =3+2*4, the multiplication (2*4) will be evaluated first because it has higher precedence than the addition (3+). This means that the result of the calculation will be 11 rather than 15 if the operations were evaluated in the opposite order. Excel follows a specific order of precedence when evaluating formulas, so it is important to understand how it works in order to get the desired result.The order of precedence in Excel is as follows: Parentheses, Exponents, Multiplication and Division, and then Addition and Subtraction. So, if a formula contains both multiplication and addition, the multiplication will be evaluated first. It is also important to note that Excel evaluates operations from left to right, even if the operations do not follow the order of precedence.To learn more about formulas for spreadsheets in Excel refer to:

Make sure you test it in main.public class ArrayWorker{/** Doubles the first 5 elements of the array */public static void doubleFirstFive(int[] values){// Notice: && i < 5for (int i = 0; i < values.length && i < 5; i++){values[i] = values[i] * 2;}}/** Write a method called tripleFirstFour() that triples the first 4 elements of the array **/public static void printArray(int[] values){for (int i = 0; i < values.length; i++){System.out.println( values[i] );}}public static void main(String[] args){int[] numArray = {3, 8, -3, 2, 20, 5, 33, 1};doubleFirstFive(numArray);printArray(numArray);}}
The code will print out the elements of the array "numArray" after they have been doubled by the "doubleFirstFive" method. The "doubleFirstFive" method takes in an array as a parameter and uses a for loop to double the value of the first 5 elements of the array, using the "&& i < 5" condition in the for loop to ensure that only the first 5 elements are doubled.
A similar method called "tripleFirstFour" that triples the first 4 elements of the array can be written as follows:
----------------------------------------------------------------------------
// Notice: && i < 4
for (int i = 0; i < values.length && i < 4; i++){
values[i] = values[i] * 3;
}
}
------------------------------------------------------------------
To test the method, you can add the following code in the main method:
-------------------------------------------------------------
tripleFirstFour(numArray);
printArray(numArray);
-------------------------------------------------------------
This will call the "tripleFirstFour" method on the numArray and then print the new array out on the console.
Design an algorithm that will take a list of numbers and partially reverse it, without making use of a second list variable. Starting at each end, the alternating entries of the list should be swapped. (Your solution may not use python's reverse function or slicing.)
Example of the algorithm:
Input = [1, 2, 3, 4, 5, 6, 7, 8]
Output = [8, 2, 6, 4, 5, 3, 7, 1]
----------------------------------------------------
Input = [1, 2, 3, 4, 5, 6, 7, 8, 9]
Output = [9, 2, 7, 4, 5, 6, 3, 8,1]
----------------------------------------------------
Input = [1, 2]
Output = [2 ,1]
----------------------------------------------------
Input = [1 , 2 , 3]
Output = [3 , 2 ,1]
----------------------------------------------------
i. Work out the steps to figure out a concrete example and briefly explain your work and thinking
ii. Find and describe a pattern and attempt to generalize
iii. Investigate and explain all special cases to see if the pattern holds up
iv. Come up with a solution and write your own python function rearrange_list(my_list: list) that rearranges the list as described above
The function should return the altered list (not a new or different list variable).
Call your function with various lists to test it, print the list before and after the call to test it.
i. To work out the steps for the example input [1, 2, 3, 4, 5, 6], I would start by initializing two pointers, one at the beginning of the list and one at the end.
I would then swap the first and last elements, then move the pointers inwards one step and repeat the process until the pointers meet in the middle. The output in this case would be [3, 2, 1, 4, 5, 6].
ii. The pattern that emerges is that the first and last elements are always swapped, then the pointers move inwards one step, then the next pair of first and last elements are swapped, and so on until the pointers meet in the middle.
iii. Special cases to consider include lists with an odd number of elements, in which case the middle element does not need to be moved, and lists with only one or two elements, in which case no swapping needs to be done.
iv. A solution in python could be as follows:
def rearrange_list(my_list):
left_pointer = 0
right_pointer = len(my_list) - 1
while left_pointer < right_pointer:
my_list[left_pointer], my_list[right_pointer] = my_list[right_pointer], my_list[left_pointer]
left_pointer += 1
right_pointer -= 1
return my_list
test_list = [1, 2, 3, 4, 5, 6, 7, 8]
print("Original list:", test_list)
print("Rearranged list:", rearrange_list(test_list))
This function can be tested with different lists .
