Use the set A = { a, b, c ,d } to answer the following questions.
What is the cardinality of A?
What is the power set of ℘(A)?
What is the cardinality of the power set?
What is the power set of A = { }
Answer:
What is the cardinality of A? 4
What is the power set of ℘(A)?
P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}
What is the cardinality of the power set? 16
What is the power set of A = { }? => {{ }} or {Ф
Explanation:
Given set is:
A = {a,b,c,d}
What is the cardinality of A?
The cardinality of set is the number of elements in the set
Since, set A has four members the cardinality is 4.
i.e.
n(A) = 4
What is the power set of ℘(A)?
The power set of a set consists of all the subsets of a set.
So the power set of A will consist of all subsets of A.
The power set is:
P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}
What is the cardinality of the power set?
The number of subsets of a set is the cardinality of power set.
As A is 4 members,
Cardinality of Power set of A = 2^4 = 16
What is the power set of A = { }
As A is an empty set, its power set will have only one element (Ф) as member
P(A) = {{ }} or {Ф}
Hence,
What is the cardinality of A? 4
What is the power set of ℘(A)? P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}
What is the cardinality of the power set? 16
What is the power set of A = { }? => {{ }} or {Ф
In programming languages, ____ is used as a mnemonic representation for the program instruction’s memory address.
Answer:
Assembly language
Explanation:
Assembly language writes instructions in human letters. Every machine language instruction has a corresponding assembly language instruction that means exactly the same thing. Assembly language uses a symbolic form of a program which are capable of:
- readable by human beings (+/-)
- constants, addresses, and names of symbolic instructions
- arithmetic during assembly - calculations of addresses, constants
- synthetic instructions (not supported by our assembler)
- expansion of macroinstructions (not supported by our
assembler)
- assembly instructions (pseudo-instructions)
• memory allocation
• memory initialization
• conditional assembly (not supported by our assembler)

Explanation:
A user invokes an app that writes a file. The app displays a progress bar that shows how much of the file has been written. Just as the progress bar reaches 50%, the battery fails and the device crashes. When the user reboots the device, he or she discovers that less than 20% of the file has actually been written. Explain why the app reported writing 50%. Frame your answer in terms of the design of I/O device drivers.
Answer:
The app reported writing 50% before the battery fails is because while writing, the data is been saved in the secondary memory via a buffer and not directly to the primary memory ( RAM ) and its returned from the secondary memory via the buffer to the primary memory
Explanation:
The app reported writing 50% before the battery fails is because while writing, the data is been saved in the secondary memory via a buffer and not directly to the primary memory ( RAM ) and its returned from the secondary memory via the buffer to the primary memory
What the app displays as a progress bar is from the Buffer, this is because as the developer was designing the app he wanted the data entry to be very fast hence he had to send the file through a buffer with the aid of a workstation he designed. so if the secondary storage is slow in returning the data back to the primary memory as fast as it entered the secondary memory via the Buffer, Then the percentage of the file that would be displayed as written when the system reboots will be less than what the app displayed before the reboot i.e. 20% < 50%

Write a loop that fills an array int values[10] with ten random numbers between 1 and 100. Write code for two nested loops that fill values with ten different random numbers between 1 and 100.
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
int[] array = new int[10];
int index = 0;
while(index < array.size()){
int number = (rand() % 100) + 1;
for (int i = 0; i < 1; i++) {
array[index] = number;
cout<< "Position "<< index << "of the array = "<< number << endl;
++index;
}
}
}
Explanation:
The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.

Write a loop that sets each vector element to the sum of itself and the next element, except for the last element which stays the same. Be careful not to index beyond the last element. Ex:Initial scores: 10, 20, 30, 40Scores after the loop: 30, 50, 70, 40The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last element remains the same. Sample program:#include #include using namespace std;int main() { const int SCORES_SIZE = 4; vector bonusScores(SCORES_SIZE); int i = 0; bonusScores.at(0) = 10; bonusScores.at(1) = 20; bonusScores.at(2) = 30; bonusScores.at(3) = 40; for (i = 0; i < SCORES_SIZE; ++i) { cout << bonusScores.at(i) << " "; } cout << endl; return 0;}
Answer:
Add the following lines of code to the already existing code segment
for (i = 0; i < SCORES_SIZE-1; ++i) {
bonusScores.at(i) = bonusScores.at(i) + bonusScores.at(i+1);
}
Explanation:
To do the task in the question, we have to iterate through the vector from the first element i.e. element at index 0 to the second to the last element; i.e. element at last index - 1
We then add each element in this iteration with the next.
This iterates through the vector from 0 to SCORES_SIZE - 1
for (i = 0; i < SCORES_SIZE-1; ++i) {
This adds each vector element with the next
bonusScores.at(i) = bonusScores.at(i) + bonusScores.at(i+1);
}
The above should be added before
for (i = 0; i < SCORES_SIZE; ++i) {
cout << bonusScores.at(i) << " ";
}
Also, I've made other modifications to the program.

The _________ operator returns the distance in bytes, of a label from the beginning of its enclosing segment, added to the segment register.a) TYPEb) SIZEOFc) OFFSETd) LENGTHOFe) PTR
Answer:
C. Offset.
Explanation:
An offset operator can be defined as an integer that typically illustrates or represents the distance in bytes, ranging from the beginning of an object to the given point (segment) of the same object within the same data structure or array. Also, the distance in an offset operator is only valid when all the elements present in the object are having the same size, which is mainly measured in bytes.
Hence, the offset operator returns the distance in bytes, of a label from the beginning of its enclosing segment, added to the segment register.
For instance, assuming the object Z is an array of characters or data structure containing the following elements "efghij" the fifth element containing the character "i" is said to have an offset of four (4) from the beginning (start) of Z.

The public static method named evens that takes in 1 argument int a, and returns a String containing all positive even numbers with each separated by a comma is in explanation part.
What is programming?The process of creating a set of instructions that tells a computer how to perform a task is known as programming.
Here's a possible implementation in Java:
public static String evens(int a) {
if (a < 0) {
return "NONE!";

Given two integer arrays, largerArray with 4 elements, and smallerArray with 3 elements. What is the result after this code executes?for = 0; i < 45 ++) { LargerArray) = smallerArray(); A. All of the elements of secondArray will get copied to firstArray. B. Error: The two arrays are not the same size. C. All the elements of firstArray will get copied to secondArray D. Some of the elements of firstArray will get copied to secondArray,
Answer:
A. All of the elements of secondArray will get copied to firstArray.
Explanation:
The correct iteration code is:
for(i =0; i<4;++i) {
largerArray[i] = smallerArray[i];
}
From the question, we understand that the largerArray has a size of 4 elements while the smallerArray has a size of 3 elements
Take for instance largerArray is {1,2,3,4} and smallerArray is {5,6,7}
Next, we analyze the loop
1. for(i =0; i<4;++i) { --->This iterates from index 0 to index 3
2. largerArray[i] = smallerArray[i]; ---- > This assigns the elements of the smallerArray to largerArray.
However, it should be noted that the smallerArray has a maximum index of 2 while the largerArray has a maximum index of 3
The content of largerArray after the iteration will be:
largerArray = {5,6,7,5}
This is so because,
When i = 0
largerArray[0] = smallerArray[0] = 5
When i = 1
largerArray[1] = smallerArray[1] = 6
When i = 2
largerArray[2] = smallerArray[2] = 7
When i = 3
largerArray[3] = smallerArray[0] = 5
Notice that the last iteration refers to smallerArray[0]; this is so because index 3 do not exist in smallerArray. Hence, the index will be returned to the first index of the smallerArray
Taking largerArray as the firstArray and smallerArray as the secondArray.
We can conclude that option A answers the question because all elements in smallerArray is copied to firstArray

. Linux servers are typically stored in a locked server closet to prevent physical access by unauthorized persons. Describe why these physical restrictions are warranted
Answer:
Following are the solution to this question:
Explanation:
Physical Access to Linux Servers:
Unauthorized staff is denied access to windows server due to various reasonable factors which might damage databases and then all database depends.
Linux distributions handle their servers but it is almost important that they will be protected or hackproof to safeguards their organizations' networks.
Guess if an unwanted staff has access to the server, he/she can be using the device by just placing a simple USB or dragging the information of the database to study it even further. Here that the results stay throughout the possession of even an unauthorized person, whom no organization wants to confront.
Its attacker may also damage that server by installing a virus or any virus mostly on the server. User security can allow unauthorized staff to go on a search and retrieve the database to disc inside the database.
Warranted physical limitations:
All such physical constraints are assured because the company cannot manage a minor error in physical security.
Because conflicts with both the physical limitation will damage its database so much but leave all loopholes free to that same protection of attackers and operators.
Its physical safety guarantee should be maintained by routine server room checks and ensure that every step of safety is undertaken and results are achieved.
