Answer:
The answer here is False.
Explanation:
Encryption protects the data and not access to data.
In some cases, the hacker may not necessarily be trying to access or decrypt the data. They may prevent one from accessing it by placing a Ransomeware virus on it.
What a Ransomeware virus would do is to prevent the legal and rightful owner from accessing such data (whether encrypted or not) until their demands are met.
In many cases, they would ask for monies or cryptocurrencies.
Another way hackers attempt to get encrypted files is to try to get the decryption keys instead. The best practice against this is to keep decryption keys manually or in a password manager. Another way to protect very sensitive information is to have sensitive systems isolated from the internet.

Explanation:
if 100 KB file is stored in 2 MB folder how many files can be stored in the folder
Answer:
20 files.
Explanation:
Given the following data;
Size of file = 100 kilobytes.
Folder size (memory) = 2 megabytes.
Method 1
1000 kilobytes = 1 megabytes.
100 kilobytes = x megabytes
Cross-multiplying, we have;
1000x = 100
x = 100/1000
x = 0.1 mb
Now, to find the number of files that can be stored;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2}{0.1} [/tex]
Number of files = 20 files.
Method II
We know that;
1 kilobytes = 0.001 megabytes. 100 kilobytes = 0.1 megabytes. 1000 kilobytes = 1 megabytes. 2000 kilobytes = 2 megabytes.Substituting into the formula, we have;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2000}{100} [/tex]
Number of files = 20 files.

Little Italy Pizza charges $14.95 for a 12-inch diameter cheese pizza and $17.95 for a 14-inch diameter cheese pizza. Write the pseudocode for an algorithm that calculates and displays how much each of these earns the establishment per square inch of pizza sold. (Hint: You will need to first calculate how many square inches there are in each pizza.)
Answer:
Following are the pseudocode to this question:
Declare variables A1, A2, B1, B2, C1,C2
Initialize B1 to 14.95
Initialize B2 to 17.95
Calculate A1=3.14*12*12/4
Calculate A2=3.14*14*14/4
Calculate C1=B1/A1
Calculate C2=B2/A2
PRINT "12 inches pizza earns $"+C1+" PER square inch"
PRINT "14 inches pizza earns $"+C2+" PER square inch"
Explanation:
In the above-given code, six variable "A1, A2, B1, B2, C1, and C2" is declared, in which "B1 and B2" is used for initializing the given value, in the next step "A1, A2, C1, and C2" variable is declared that calculates and store its values and use the print method to print its stored value with the message.

Which of the following are the functions of an os?
Temperature converter. This program should prompt the user for two arguments, first a decimal number and second, a single letter, either C or F. The decimal represents a temperature, the character represents which system that degree is in (50.0 F would be 50.0 degrees Fahrenheit etc.). This program should take the given number and convert it to a temperature in the other system. The output string format should be degree(s) is equal to degree(s) . Eg. input 0 C would give the string 0.0000 degree(s) C is equal to 32.0000 degree(s) F. You can assume that either F or C will be given for input, no need to account for invalid input.

Computer networks allow an unlimited amount of computers to communicate with each other. This is especially useful in enterprise environments, as technicians have to deal with hundreds of computers at a time. Computer networks make it easier to share files, increase storage capacity, better communication, easier to to control computers remotely, easier to share resources, ability to share a single internet connection on multiple devices. Computer networks also have a lot of cost benifits too, as network administration is centralised, meaning that less IT support is required, and you can cut costs on sharing peripherals and internet access.

In this lab, you use the flowchart and pseudocode found in the figures below to add code to a partially created C++ program. When completed, college admissions officers should be able to use the C++ program to determine whether to accept or reject a student, based on his or her test score and class rank.
start input testScore,
classRank if testScore >= 90 then if classRank >= 25 then output "Accept"
else output "Reject" endif else if testScore >= 80
then if classRank >= 50 then output "Accept" else output "Reject" endif
else if testScore >= 70
then if classRank >= 75 then output "Accept"
else output "Reject"
endif else output "Reject"
endif
endif
endif
stop
Study the pseudocode in picture above. Write the interactive input statements to retrieve: A student’s test score (testScore) A student's class rank (classRank) The rest of the program is written for you. Execute the program by clicking "Run Code." Enter 87 for the test score and 60 for the class rank. Execute the program by entering 60 for the test score and 87 for the class rank.
[comment]: <> (3. Write the statements to convert the string representation of a student’s test score and class rank to the integer data type (testScore and classRank, respectively).)
Function: This program determines if a student will be admitted or rejected. Input: Interactive Output: Accept or Reject
*/ #include using namespace std; int main()
{ // Declare variables
// Prompt for and get user input
// Test using admission requirements and print Accept or Reject
if(testScore >= 90)
{ if(classRank >= 25)
{ cout << "Accept" << endl; }
else
cout << "Reject" << endl; }
else { if(testScore >= 80)
{ if(classRank >= 50)
cout << "Accept" << endl;
else cout << "Reject" << endl; }
else { if(testScore >= 70)
{ if(classRank >=75) cout << "Accept" << endl;
else cout << "Reject" << endl; }
else cout << "Reject" << endl; } } } //End of main() function
Answer:
The equivalent program in C++:
#include<iostream>
#include <sstream>
using namespace std;
int main(){
string Score, Rank;
cout<<"Enter student score and class rank: ";
cin>>Score>>Rank;
int testScore = 0, classRank = 0;
stringstream sstream(Score);
sstream>>testScore;
stringstream tream(Rank);
tream>>classRank;
if (testScore >= 90){
if(classRank >=25){cout<<"Accept";}
else{cout<<"Reject";}
}
else if(testScore >= 80){
if(classRank >=50){cout<<"Accept";}
else{cout<<"Reject";}
}
else if(testScore >= 70){
if(classRank >=75){cout<<"Accept";}
else{cout<<"Reject";}
}
else{cout<<"Reject";}
return 0;
}
Explanation:
This declares Score and Rank as string variables
string Score, Rank;
This prompts the user for score and class rank
cout<<"Enter student score and class rank: ";
This gets the user input
cin>>Score>>Rank;
This declarees testScore and classRank as integer; and also initializes them to 0
int testScore = 0, classRank = 0;
The following converts string Score to integer testScore
stringstream sstream(Score);
sstream>>testScore;
The following converts string Rank to integer classRank
stringstream tream(Rank);
tream>>classRank;
The following conditions implement the conditions as given in the question.
If testScore >= 90
if (testScore >= 90){
If classRank >=25
if(classRank >=25){cout<<"Accept";}
If otherwise
else{cout<<"Reject";}
} ---
If testScore >= 80
else if(testScore >= 80){
If classRank >=50
if(classRank >=50){cout<<"Accept";}
If otherwise
else{cout<<"Reject";}
}
If testScore >= 70
else if(testScore >= 70){
If classRank >=75
if(classRank >=75){cout<<"Accept";}
If otherwise
else{cout<<"Reject";}
}
For testScore less than 70
else{cout<<"Reject";}

Explanation:
HTML, the markup language of the web, specifies colors using the RGB model. It uses a two-digit hexadecimal (that is, base 16) representation for each component of the vector, and concatenates the three numbers together to form one large, six-digit number. For instance, the HTML color code #80FF3B has red component 80, green component FF, and blue component 3B. In hexadecimal, the digits 0 through 9 have their usual meanings, but the letters A through F also function as digits, and have the meanings 10 through 15, respectively. Because hexadecimal means base 16, a two-digit number such as 3B thus has the meaning 16⋅3+11=59. The 16 is used because the 3 is in the 16s place, and the 11 is the meaning of the digit B. (If you found this introduction to hexadecimal notation too brief, consult the web for more details.) What is the maximum number representable with two hexadecimal digits?
Solution :
It is given that :
The digits 0 through 9 in hexadecimal have their usual meanings. But letters A through F function like the digits and it means digits 10 through 15, respectively.
Now the base of a hexadecimal is 16.
Now we know from 0 to 9 [tex]$\rightarrow$[/tex] A, B, C, D, E, F
Now the maximum two digits hexadecimal numbers are = F F
So, F F [tex]$= 16 \times 15 + 16^0 \times 15$[/tex]
= 255

Write two alternate functions specified below, each of which simply triples the variable count defined in main. These two functions are: a. Function tripleByValue that passes a copy of count by value, triples the copy and returns the new value.b. Function tripleByReference that passes count by reference via a reference parameter and triples the original value of count through its alias(i.e. the reference parameter)For example, if count
Answer:
Following are the code to this question:
#include <iostream>//header file
using namespace std;
int triplebyValue(int count)//defining a method triplebyValue
{
int x=count*3;//defining a variable x that multiply by 3 in the count
return x;//return value of x
}
void triplebyReference(int& count)//defining a method triplebyReference that hold count variable as a reference in parameter
{
count*=3;//multipling a value 3 in the count variable
}
int main()//main method
{
int count;//defining integer variable
count=triplebyValue(3);//use count to call triplebyValue method
cout<<"After call by value, count= "<<count<<endl;//print count value with message
triplebyReference(count);//calling a method triplebyReference
cout<<"After call by reference, count= "<<count<<endl;//print count value with message
return 0;
}
Output:
After call by value, count= 9
After call by reference, count= 27
Explanation:
In this code two methods "triplebyValue and triplebyReference" are declared, which accepts a count variable as a parameter, and in both multiply the count value by 3 and return its value.
Inside the main method, an integer variable "count" is declared that first calls the "triplebyValue" method and holds its value into count variable and in the next, the method value is a pass in another method that is "triplebyReference", and use print method to print both methods value with a message.
