The answer in the blank is bit error rate, for it is where
errors usually occurs and this happens during the digital data transmission.
Because of the errors that it is being managed, it divides those errors by the
total number of bits that are being transmitted during the process. It happens
within a given period.
Answer:
The solution code is written in Python 3
- total = 0
- count = 0
- neg = 0
- pos = 0
-
- num = int(input("Enter an integer: "))
-
- while(num != 0):
- total += num
- count += 1
-
- if(num < 0):
- neg += 1
- else:
- pos += 1
-
- num = int(input("Enter an integer: "))
-
-
- print("The number of positives: " + str(pos))
- print("The number of negatives: " + str(neg))
- print("The total is " + str(total))
- print("The average is " + str(total/count))
Explanation:
Firstly, we create four variables, <em>total</em> , <em>count,</em> <em>neg</em> and <em>pos </em>(Line 1- 4). This is to prepare the variable to hold the value of summation of input integer (<em>total</em>), total number of input number (<em>count</em>), total negatives (<em>neg</em>) and total positives (<em>pos</em>).
Next, we prompt user for the first integer (Line 6).
Create a sentinel while loop and set the condition so long as the current input number, <em>num</em> is not equal to zero. the program will just keep adding the current <em>num</em> to total (Line 9) and increment the count by one (Line 10).
if <em>num</em> smaller than zero, increment the <em>neg</em> by one (Line 13) else increment the <em>pos </em>by one (Line 15). This is to track the total number of positives and negatives.
Finally, we can display all the required output (Line 20 - 23) using the Python built-in function <em>print()</em> when user enter 0 to terminate the while loop. The output shall be as follows:
The number of positives: 3
The number of negatives: 1
The total is 5
The average is 1.25
Answer: Mutual authentication
Explanation: Mutual authentication could be referred to a vetting process where the two entities in communication authenticate each other, it could also be referred to as a two-way authentication.
In the scenario above, the cloud service or server authenticates itself with the client and the client authentication itself with the cloud service server by verifying or vetting the certificates of both communicating entities before a secure encrypted connection would be established or created.
Answer:
import java.util.Scanner;
public class num10 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter a word");
String word = in.nextLine();
String reversed = "";
//Get the length of the string entered
int length = word.length();
//Loop through the string and reverse th string
for ( int i = length - 1; i >= 0; i-- )
reversed = reversed + word.charAt(i);
//Compare the two strings "word" and "reversed"
if (word.equals(reversed))
System.out.println(word+" is a palindrome");
else
System.out.println(word+" is not a palindrome");
}
}
Explanation:
Since we know that a palindrome word is a word that reads the same forward and backward, The Idea here is:
- To obtain a word from a user.
- Use a for loop to reverse the word and store in another variable
- Use if....else to compare the two strings and determine if they are equal, if they are equal then the word is palindrome.
