Complete Question:
Let's say that you handle the IT systems administration for your company. There's a server inside of your organization that checks how often client machines access it. If a client machine hasn't accessed the server in three months, the server won't allow the client machine to access its resources anymore. What can you set to make sure that your client machines and the server times are in sync?
Answer:
Network Time Protocol (NTP).
Explanation:
As the IT systems administrator, you can set the network time protocol (NTP) to make sure that your client machines and the server times are in synchronization.
A network time protocol (NTP) can be defined as an internet standard protocol which is used by an IT system administrator to synchronize a computer's clock to a particular time reference over packet switched or local area network (LAN) and variable-latency data networks. NTP was developed at the University of Delaware by Professor David L. Mills.
<em>Basically, the network time protocol uses the coordinated universal time (UTC) and a client-server model to measure the total round-trip delay for a computer process. </em>

public class MagicSquare {
public static void main(String[] args) {

{13, 2, 7,12},
{ 3, 16, 9, 6},
{10, 5, 4, 15}
};
System.out.printf("The square %s a magic square. %n",
(isMagicSquare(square) ? "is" : "is not"));
}
public static boolean isMagicSquare(int[][] square) {
if(square.length != square[0].length) {

}
int sum = 0;

}
int d1 = 0, d2 = 0;

int row_sum = 0;
int col_sum = 0;
