To create a public key signature, you would use the ______ key.
Answer:
To create a public key signature, you would use the _private_ key.
Explanation:
To create a public key signature, a private key is essential to enable authorization.
A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.
The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.
The public key uses different keys to make data readable and unreadable.
The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.

Write a for loop that reads an integer from the user, and prints the sum of numbers from 1 to that integer (inclusive). If the user enters a number less than 1, he/she should be prompted to enter a number greater or equal to 1.
Answer:
Written in Python
num = int(input("Number: "))
while num < 1:
num = int(input("Number: "))
total = 0
for i in range(1, num+1):
total= total + i
print("Total: "+str(total))
Explanation:
This line prompts user for input
num = int(input("Number: "))
The following iteration checks and prompts user for valid input
while num < 1:
num = int(input("Number: "))
This initializes total to 0
total = 0
The following iteration adds from 1 to input number
for i in range(1, num+1):
total= total + i
This displays the total
print("Total: "+str(total))
4.16 LAB: Varied amount of input data Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics. Ex: If the input is: 15 20 0 5 -1 the output is: 10 20 You can assume that at least one non-negative integer is input. 254058.1561406
Answer:
Here is the C program. Let me know if you want the program in some other programming language.
#include <stdio.h> //to use input output functions
int main() { //start of main function
int num; // to store input numbers
int sum = 0; //to store the sum of numbers
scanf("%d", &num); //reads the numbers from user
int count = 0; //to count the total numbers entered by user
int max = 0; //to store the maximum of numbers
while(num >= 0) { //continues to execute until user enters negative number
sum+=num; //adds the numbers
scanf("%d", &num); //reads the numbers from user
count++; //counts the numbers entered
if(num>=max){ //if number is greater than numbers stored in max
max = num; } } //assigns that maximum number to max
printf("%d %d", sum/count,max); } //displays the average of numbers and maximum of numbers
Explanation:
I will explain the program with an example. Lets say the first number input by user is 15. Then the loop works as follows:
At first iteration:
num >= 0 is true because 15 is greater than 0 so program moves to the body of loop
sum+=num; becomes:
sum = sum + num
sum = 0 + 15
sum = 15
count++; becomes:
count = count + 1
count = 0 + 1
count = 1
if(num>=max) means if(15>=0) this is true so
max = num; this becomes:
max = 15
Lets say the next value entered by user is 20. It is stored in num variable
At second iteration:
num >= 0 is true because 20 is greater than 0 so program moves to the body of loop
sum+=num; becomes:
sum = sum + num
sum = 15 + 20
sum = 35
count++; becomes:
count = count + 1
count = 1 + 1
count = 2
if(num>=max) means if(20>=15) this is true so
max = num; this becomes:
max = 20
Lets say the next value entered by user is 0. It is stored in num variable
At third iteration:
num >= 0 is true because 0 is equal to 0 so program moves to the body of loop
sum+=num; becomes:
sum = 35 + num
sum = 35 + 0
sum = 35
count++; becomes:
count = count + 1
count = 2 + 1
count = 3
if(num>=max) means if(0>=20) this is false so
max = num; this remains:
max = 20
Lets say the next value entered by user is 5. It is stored in num variable
At fourth iteration:
num >= 0 is true because 5 is greater than 0 so program moves to the body of loop
sum+=num; becomes:
sum = 35 + 5
sum = 35 + 5
sum = 40
count++; becomes:
count = count + 1
count = 3 + 1
count = 4
if(num>=max) means if(5>=20) this is false so
max = num; this remains:
max = 20
Lets say the next value entered by user is -1. It is stored in num variable
Now the loop breaks because num >= 0 is false because -1 is less than 0 so program moves to the statement:
printf("%d %d", sum/count,max);
This has two parts to print on output screen:
sum/count which is 40/4 = 10
max which is 20
So the output of the entire program is:
10 20
The screenshot of program along with its output is attached.
The program that takes any number of non-negative integers as input, and outputs the average and max is coded below.
The program written in Python that takes non-negative integers as input, calculates the average and maximum, and stops when a negative integer is encountered:
numbers = []
num_sum = 0
max_num = float('-inf')
while True:
num = int(input("Enter a non-negative integer (enter a negative integer to stop): "))
if num < 0:
break
numbers.append(num)
num_sum += num
max_num = max(max_num, num)
if len(numbers) > 0:
average = num_sum / len(numbers)
print("Average:", average)
print("Max:", max_num)
else:
print("No non-negative integers were entered.")
In this program, we start by initializing an empty list `numbers` to store the non-negative integers.
We also initialize variables `num_sum` to keep track of the sum of the numbers and `max_num` to track the maximum number encountered.
We then use a while loop that continues until a negative integer is entered. Inside the loop, we prompt the user to enter a non-negative integer. If the number is negative, the loop is terminated using the `break` statement. Otherwise, we append the number to the `numbers` list, update the sum `num_sum`, and check if it is greater than the current `max_num`.
After exiting the loop, we calculate the average by dividing the sum by the number of elements in the `numbers` list (which is obtained using the `len()` function). Finally, we print the average and the maximum value.

Their compression is lossy.
The correct answer would BE (puns) B. They are limited to 256 colors
The statement that is true regarding GIF is that they are limited to 256 colors. The correct option is B.
What is GIF?GIF (graphics interchange format) is a digital file format invented in 1987 by Internet service provider CompuServe to reduce the size of images and short animations.
GIFs are short animations and video clips. GIFs are frequently used to represent a feeling or action.
LZW compression is used in the GIF format, which is a lossless compression method.
However, because GIF files are limited to 256 colors, optimizing a 24bit image as an 8bit GIF can result in color loss. GIF is a raster data format originally developed for simple images that are commonly found on the internet.
In a browser, you can control how colors dither and choose the number of colors in a GIF image.
Thus, the correct option is B.

Write a function that takes as input two parameters: The first parameter is a positive integer representing a base that is guaranteed to be greater than 1. The second parameter is an integer representing a limit. The function should return a list containing all of the non-negative powers of the base less than the limit (not including the limit). The powers should start at base^0=1 and increase from there until the limit. If the limit is less than 1 the functions should just return an empty list
Answer:
Written in Python:
def powerss(base, limit):
outputlist = []
i = 1
output = base ** i
while limit >= output:
outputlist.append(output)
i = i + 1
output = base ** i
return(outputlist)
Explanation:
This declares the function
def powerss(base, limit):
This creates an empty list for the output list
outputlist = []
This initializes a counter variable i to 1
i = 0
This calculates base^0
output = base ** i
The following iteration checks if limit has not be reached
while limit >= output:
This appends items to the list
outputlist.append(output)
The counter i is increased here
i = i + 1
This calculates elements of the list
output = base ** i
This returns the output list
return(outputlist)
Assume you are using an array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements, dequeue 5 elements, and then enqueue 1 more element. Which index of the internal array elements holds the value of that last element you enqueued
Answer:
The answer is "5".
Explanation:
In the queue based-array, it follows the FIFO method, and in the question, it is declared that a queue has a capacity of 10 elements, and insert the 5 elements in the queue and after inserting it enqueue 5 elements and at the last, it inserts an element 1 more element on the queue and indexing of array always start from 0, that's why its last element index value is 5.
Custom function definitions:________.
A. Must be written before they are called by another part of your program
B. Must declare a name for the function
C. Must include information regarding any arguments (if any) that will be passed to the function
D. all of the above
Answer:
D. all of the above
Explanation:
A option is correct and function definition must be written before they are called by another part of your program. But in languages such as C++ you can write the prototype of the function before it is called anywhere in the program and later write the complete function implementation. I will give an example in Python:
def addition(a,b): #this is the definition of function addition
c = a + b
return c
print(addition(1,3)) #this is where the function is called
B option is correct and function definition must declare a name for the function. If you see the above given function, its name is declared as addition
C option is correct and function definition must include information regarding any arguments (if any) that will be passed to the function. In the above given example the arguments are a and b. If we define the above function in C++ it becomes: int addition( int a, int b)
This gives information that the two variables a and b that are parameters of the function addition are of type int so they can hold integer values only.
Hence option D is the correct answer. All of the above options are correct.
