Answer: Server based network
Explanation:
The server based network is the type of network in which the special type of computer mainly handle the various networking tasks like the storing file, managing printers and authenticate the users in the system. The server based network are also responsible for run various types of application like the email and the database system.
The microsoft windows 2016 and the window 2012 are the two ideal OS (Operating system) that mainly used in the server based network.
Therefore, we use the server based network as it easy to backup and manage in the networking system.
Answer:
Explanation:
The following code is written in Python. It creates a class that takes in one ArrayList parameter and loops through it and calls two functions that check if the numbers are Perfect, Odd, or Even. Then it goes counting each and printing the final results to the screen.
class NumberAnalyzer:
def __init__(self, myArray):
perfect = 0
odd = 0
even = 0
for element in myArray:
if self.isPerfect(element) == True:
perfect += 1
else:
if self.isEven(element) == True:
even += 1
else:
odd += 1
print("# of Perfect elements: " + str(perfect))
print("# of Even elements: " + str(even))
print("# of Odd elements: " + str(odd))
def isPerfect(self, number):
sum = 1
i = 2
while i * i <= number:
if number % i == 0:
sum = sum + i + number / i
i += 1
if number == sum:
return True
else:
return False
def isEven(self, number):
if (number % 2) == 0:
return True
else:
return False
Answer:
A. The function definition must appear before the function is called
Explanation:
Given
The above lines of code
Required
Determine the error in the program
In python, functions has be defined before they are called but in this case (of the given program), the function is called before it was defined and this will definitely result in an error;
<em>Hence, option A answers the question</em>
The correct sequence of the program is as follows:
<em>def evenOdd(n):
</em>
<em> if n % 2 == 0:
</em>
<em> return "even"
</em>
<em> return "odd"
</em>
<em>num = int(input("Enter an integer: "))
</em>
<em>print("The integer is", evenOdd(num))
</em>
