Answer:
Maintenance Phase
Explanation:
One of the concepts employed in project management for describing stages involved when carrying out an information system development project is the systems development life cycle (SLDC). The cycle which starts from carrying out a feasibility study and ends in maintenance is a highly used conceptual model. There are 5 major stages or phase and they are the; Requirement Phase, Design Phase; Implementation Phase, Test Phase, and the Maintenance phase. The maintenance phase comes when testing has been complete and all enhancement and modifications have already been developed, and the system is operating.

where it is in the format [email protected]:~directory$
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
A Trusted Platform Module is a specialized chip on an endpoint device that stores RSA encryption keys specific to the host system for hardware authentication. Each TPM chip contains an RSA key pair called the Endorsement Key. The pair is maintained inside the chip and cannot be accessed by software.
