Answer:
The port that should be set open to allow users to access this new server is:
TCP port.
Explanation:
Ports are openings or entrance doors through which data packages have access to a PC or server. TCP and UDP are transport protocols with port numbers. TCP means Transmission Control Protocol. They are used to connect two devices over the internet and other networks. UDP means User Datagram Protocol. They are used to connect applications and to speed the transfer of data. Comparatively, UDP is faster, simpler, and more efficient than TCP. TCP enables retransmission of lost data packets, which UDP cannot do.
Answer:
Following are the statement in C++ Language is given below
total=0; // variable declaration
cin >> amount; // Read the input
while(amount >=0) //iterating the loop
{
if(amount>0) // checking condition
total=total+amount; // perform operation
}
Explanation:
Following is the description of the statement
- Declared a variable "total" and initialized with them 0 to them.
- Read the input in the "amount" variable by using cin.
- iterating the loop when the amount is greater then 0.
- Checking the condition if(amount>0) then adding the total variable and amount and storing them into the total variable.
Answer:

Answer:
// program in Python to check perfect number
#function to find number is perfect or not
def is_Perfect_Number(n):
#total variable
tot = 1
i = 2
#sum of all divisor of number
while i*i<=n:
if n%i==0:
tot = tot + i + n/i
if tot == n and n != 1:
return 1
i = i+1
return 0
#read until user enter a perfect number
while True:
#read integer
num = int(input("Input an integer: "))
#call the function
if(is_Perfect_Number(num)):
print(num,"is perfect number")
#if perfect number break
break
else:
print(num,"is not a perfect number")
#ask again
print("try again.")
Explanation:
Read number from user and then call the function is_Perfect_Number() with parameter "num".This will find the sum of all divisor of number.If sum is equal to number then it will return 1 else return 0.If the number is not perfect then it will again ask to enter a number until user enter a perfect number.
Output:
Input an integer: 24
24 is not a perfect number
try again.
Input an integer: 28
28 is perfect number
