Answer:
The correct answer to the following question will be "True".
Explanation:
SCADA is a hardware and software elements program that permits industrial enterprises to:
- Agricultural processes are regulated locally or globally.
- The human-machine interaction program specifically interfaces with equipment such as cameras, switches, generators, motors and much more.
- Track, store, and process the data in real-time.
Therefore, the given statement is true.
Answer:
The User Datagram Protocol (UDP) is called the connectionless protocol because:
It does not attempt to fix bad packets or resend lost packets.
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:
// 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
