Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.

Explanation:
<span>Two-tiered client/server architecture.
The two-tier is based on Client Server architecture. The two-tier architecture is like client server application. The direct communication takes place between client and server. There is no intermediate between client and server. Because of tight coupling a 2 tiered application will run faster</span>
Answer:
// program in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variable
int inp_month;
cout<<"Enter month:";
// read month
cin>>inp_month;
// if month is february
if(inp_month==2)
cout<<"Number of days in month:28"<<endl;
// if month is 4 or 6 or 9 or 11
else if(inp_month==4||inp_month==6||inp_month==9||inp_month==11)
cout<<"Number of days in month:30"<<endl;
else
// for others month
cout<<"Number of days in month:31"<<endl;
return 0;
}
Explanation:
Read month from user and assign it to variable "inp_month".If month is 2 then there is 28 days in the month.If input month is 4 or 6 or 9 or 11 then there is 30 days in the month.For other month there will be 31 days in month.We assume there is no leap year.
Output:
Enter month:4
Number of days in month:30
