Answer:
I am writing the function using Python. Let me know if you want the program in some other programming language.
def iterPower(base, exp):
baseexp = 1
while exp > 0:
baseexp = baseexp*base
exp= exp - 1
return baseexp
base = 3
exp = 2
print(iterPower(base, exp))
Explanation:
- The function name is iterPower which takes two parameters base and exp. base variable here is the number which is being multiplied and this number is multiplied exponential times which is specified in exp variable.
- baseexp is a variable that stores the result and then returns the result of successive multiplication.
- while loop body keeps executing until the value of exp is greater than 0. So it will keep doing successive multiplication of the base, exp times until value of exp becomes 0.
- The baseexp keeps storing the multiplication of the base and exp keeps decrements by 1 at each iteration until it becomes 0 which will break the loop and the result of successive multiplication stored in baseexp will be displayed in the output.
- Here we gave the value of 3 to base and 2 to exp and then print(iterPower(base, exp)) statement calls the iterPower function which calculates the exponential of these given values.
- Lets see how each iteration works:
baseexp = 1
exp>0 True because exp=2 which is greater than 0
baseexp = baseexp*base
= 1*3 = 3
So baseexp = 3
exp = exp - 1
= 2 - 1 = 1
exp = 1
baseexp = 3
exp>0 True because exp=1 which is greater than 0
baseexp = baseexp*base
= 3*3 = 9
So baseexp = 9
exp = exp - 1
= 1-1 = 0
exp = 0
- Here the loop will break now when it reaches third iteration because value of exp is 0 and the loop condition evaluates to false now.
- return baseexp statement will return the value stored in baseexp which is 9
- So the output of the above program is 9.

It is an all-too-often used technology today in connecting several computers together via a network.
Routing simple terms means the action of selecting the path taken by the traffic of data in a network of computers. The routing systems involve the use of both wireless and cable based architectures. Some common example of routing systems includes:
- Dynamic Routing
- Static routing
- Default Routing

Answer: C) DNS poisoning
Explanation: DNS poisoning or DNS cache poisoning is the type of attacking tendency towards the URL of the computer. These attempt to attack the URL using the spam mails and the user usually end up clicking on the URL provided by the attacker which invokes attack in the computer.
This mechanism takes place in the emails as well as the selected websites which can be accessed by the users easily.These attacks once enter the system seems like the real thing and become prone to many risks .
