Answer:
Ronald missed the words: One-time password, Secure
Explanation:
Whenever we use public computer, there are possibilities to steal the user data by hackers. It might not be safe to use as like we have protection in personal or Office computers. But when a situation arises to use a public system, it is always recommended to use one-time password so that the logins are not misused thereafter.
Even if the hackers try to misuse, the user will get a message / authentication reply to use the login and thus we are safe. Also, always browse only secured website ie. “https”.
Answer:
The program to this question can be given as:
Program:
public class Main //define class.
{
public static void main(String[] as) //define main method.
{
int n=5; //define variable n and assign positive value.
int i,j; //define variable
for (i = 7; i>=1; i--) //outer loop.
{
for (j = 0; j< i; j++) //inner loop.
{
System.out.print("*"); //print asterisks.
}
System.out.println(); //line break.
}
}
}
Output:

Explanation:
The description of the above code can be given as:
- In the above java programming code firstly we define a class that is "Main". In this class we define a main method in the main method we define a variables that is "n" in this variable we assign a positive value. The we define another integer variable that is i,j this variable is used in the loop.
- Then we define a loop. for prints asterisks values in reverse triangle, we nested looping concept. In nested looping, we use in loop in this loop we use the i and j variables that print the asterisks value.
Answer:
voice service voip
Explanation:
Voice over Internet Protocol feature allows users to make voice calls by making use of a broadband internet connection. The Voice engineer is setting up a Cisco 2951 Integrated Services Router with Cisco Unified Communications Manager Express, which happens to fall under broadband internet connection and hence the command the engineer will enter must be a voice service voip.
Answer:
def volCylinder(r, h):
return 3.14 * r * r * h;
radius = float(input("Enter the radius: "))
height = float(input("Enter the height: "))
print("The volume of the cylinder is: "+ str(volCylinder(radius, height)))
Explanation:
- Inside the function, calculate the volume of the cylinder using the formula and return the result.
- Then, take inputs from the user for radius and height as float numbers
- Call the function and print the result
